Understand the Eye:

The eye is like a camera. When you take a picture with the camera, the lens of the camera allows the light to pass through and focuses on a film present behind inside the camera. When the light hits this film, a picture is taken.

Our eye works in the same way. The light ray from the object passes through the outer surface, the cornea, where it is bent and then passes through the lens.  There it is focused further and passes through a jelly like substance, the vitreous before it falls finally on the curtain or retina. On the retina an inverted Image of the object is formed.

Once the light energy hits the retina, the photosensitive enzymes present there trigger a chain of electrochemical reaction, which converts the light energy into electrical impulses. These impulses then travel through the optic nerves and reach the brain.

Our brain will read the information from both eyes, convert the electrical impulses into light impulses and fuse both the images and revert (erect) it. That’s how we see.

How Does The Eye Work?

Anything you see is an image that enters your eye in the form of light. The different parts of your eye collect this light and send a message to your brain, enabling you to see. For perfect vision all the parts of your eye need to work properly.

The cornea is the clear, outer layer of the eye.

The pupil is an opening that lets light enter the eye. The iris, the colored part of the eye, makes the pupil larger or smaller.

The lens bends to focus light onto the retina.

The retina receives light that has been focused by the cornea and lens.

A clear (vitreous) gel fills the inside of the eye, giving it shape.

The Cornea is clear to let light in to the eye, and curved to focus the light rays.

The different types of refractive errors are as follows:

Myopia, wherein (short sightedness) the light rays from an object are focused in front of the retina, making them look blurred. It is corrected with minus numbered lenses.

Hyperopia, wherein (Far sightedness) the light rays from an object are focused behind the retina, making them look blurred. It is corrected with plus numbered lenses.

Astigmatism, wherein the light rays from an object do not come to a single focus on retina. Instead we have ray of focus, making objects look distorted. It is corrected with cylindrical power lenses.

myopia and hyperopia

What is Myopia?

Myopia is a refractive condition in which the distance vision is blurred as the light rays are focused in front of the retina rather than on the retina. It is just an optical imbalance in the eye.

What is Hyperopia?

Hyperopia is a refractive condition in which the distance vision is blurred as the light rays are focused behind the retina rather than on the retina. It is just an optical imbalance in the eye.

What is Presbyopia?

Presbyopia is a condition of eye in which the natural crystalline lens in eye gradually loses the ability to focus for near work. The change is apparent around the age of 40 yrs and requires correction with glasses for near work.

 

 

Refractive Errors can be corrected using glasses, contact lenses or by LASIK.

1. Glasses:

Glasses of minus numbers are used for myopia and plus number for hyperopia. This is the simplest and easiest method of correction.

  • Advantages:

a. Easy to handle

b. Changes can be corrected with a new pair of glasses or contact lenses.

  • Disadvantages:

a. The rim of the spectacle hinders the visual field (side vision) which could be bother-some in very high powered number glasses.

b. Cosmetically not very acceptable.

 

2. Contact Lenses:

Contact Lenses can be used for correction of myopia and hyperopia. A lens with appropriate power is placed on the black portion (on a part of the cornea of the eye).

  • Advantages:

a. patient can enjoy full field of vision

b. Cosmetically acceptable and

c. Easily reproducible.

  • Disadvantages:

a. Needs patient motivation

b. Tolerance of lens material may be an issue

c. Hygiene

d. Can cause allergy in the eye.

e. Needs regular follow up

 

3. Lasik:

Lasik is the latest surgical technique for correction of myopia and hyperopia. It’s cutting edge, laser technology is used to reshape the front surface of the eye that is the cornea. This Improves the way the light are rays focused and enhances ones natural vision.

  • Advantage:

Reduces dependence on external eye wear like glasses or contact lenses.

  • Disadvantage:

There is a small risk of complication. However, majority of these can be managed so that the quality of vision is not affected.

What Are The Types Of Myopia?

The different types of myopia are:

1. Simple Myopia: The number usually remains constant.

2. Progressive Myopia: There are usually increases in number, more so around the age of 18 years till there is body growth.

 

What are the common symptoms noted by myopes?

(Even people having normal eyes can also at times have these symptoms):

The common symptoms noted by myopes are:

• Flashes

• Floaters

 

Facts about flashes:

They are like lightening stars or streaks of light that aren’t really there. Flashes are often caused by the vitreous (the gel filling the inside of your eye) pulling on the retina.

A few flashes are seen by everyone from time to time. Sometimes they can be signs of other eye problem that need care. As you age or if you are a myopia, you are more likely to see flashes. Sudden increase in flashes may be a sign of problem in the eye-you need to consult your eye doctor immediately.

 

Facts about floaters:

They are dark specks, clouds, thread or spider web shaped structures moving in your field of vision. Most people see them once in a while.

As you grow older you are more likely to notice floaters. They can also be caused by eye injuries.

If they have appeared suddenly or increased in number, they may be a sign of eye problem that needs care- consult an eye doctor immediately.

 

What can happen to your retina in myopia?

The following can happen to your retina in myopia:

 

1. Lattice Degeneration:

Lattice degeneration are weak spots in the retina which are caused because of enlarged size of the eyeball. These could lead to retinal detachment in patients with symptoms and a family history of retinal detachment.

Treatment: The weak spots are sealed with laser or cryo treatment. It is treated only if the symptoms are present and the best person to judge is your eye doctor specialized in vitreo retina.

2. Retinal hole or tear

Causes:

. Injury

. Lattice degeneration not being treated

. Spontaneous

Treatment: Retinal hole or tear may need cryo or laser.

 

3. Retinal detachment

Retinal detachment is separation of retina from the back wall of the eye. Treatment: Surgery.

Cover your left eye with the palm of your hand and look at your right eye in a mirror.

While you are looking at your eye in the mirror, try to see all four corners and sides of the mirror without moving your eye up or down or from side to side.

Now, cover your other eye and perform the same test.

You have just completed testing the peripheral vision of each eye. If you notice any peripheral vision loss, or any visual changes, distortion, or blur that was not present the day before, notify your eye doctor immediately.

Q.    If l undergo LASIK or if switch to contact lens, do l still have same chances of developing retinal detachment?  

A.     You must clearly understand that neither the contact lens nor LASIK corrects your pathology associated with myopia. All they do is they correct the optical part of the myopia. So despite undergoing LASIK or switching to contact lens, you still have the effect of myopia on the retina, hence it is necessary to have regular up with your retinal specialist.    

 

Q.   If I see floaters or flashes, do I have to rush to my doctor?   

A.     Floaters or flashes are important signs of retinal tear or detachment. Though these symptoms may not be serious, it is better to consult an eye doctor, who is specialized in vitreo retinal diseases to rule out retinal detachment and for further treatment if required.   

                 

Q.    Should l restrict my activities if I have Myopia?

A.     According to one school of thought, it was considered advisable to restrict myopic patients from bending down, reading in excess, seeing television and carrying heavy weights to prevent retinal detachment. The latest belief is that no such restriction is required; direct trauma should be avoided and the person should periodically have their eye checked. 

Retinal detachment occurs due to abnormal vitreo retinal relationship rather than due to reading, watching television, carrying weight or bending down. These could be just due to mere coincidence. A retinal detachment, on the other hand, can occur even during sleep.

Retinal detachment occurs only due to vitreo retinal changes. Restrictions, if any, are laid temporarily before and after surgery. Following this person can lead a normal life.The only precaution they need to take is to have a thorough retina checkup with indirect opthalmoscope by retinal surgeon at regular intervals. Majority of myopic changes can go undiagnosed if the retinal evaluation is not done by indirect ophthalmoscope, which could cost your precious eye sight and consequently your life style.

Cataract formation is a natural part of the eye's aging process. Cataract surgery is a common eye operation.

Cataract formation is a natural part of eye’s aging process. Most people regain the vision they had earlier with the help of microsurgery. The procedure has a 98% success rate. There is very little discomfort or inconvenience and patients can usually return home few hours after surgery.

Here is some general information about what you can expect before, during and after your cataract surgery.

What is a cataract?

Anything you see is an image that enters your eye in the form of light. Inside your eye is a lens, much like the lens of a camera. The lens focuses the light rays coming through the pupil onto the retina at the back of the eye. The different parts of the retina collect this light and send a message to your brain, enabling you to see.

For perfect vision the lens should be clear so that light can pass through it and reach the retina. When the lens becomes cloudy or opaque, light cannot pass through it and the vision become dim or blurred. A cloudy lens is called a cataract. A cataract is not a growth or a film over the eye - it is a cloudiness of the natural lens inside your eye.

What are the causes of cataract?

The most common cause of cataract is the deterioration of the normal structure within the lens of the eye with age. There may be other causes like diabetes, kidney disease, glaucoma, smoking, eye injuries, infection, and inflammation inside the eye. Prolonged use of certain medications can also lead to cataract formation.

How Is Cataract Detected?

A thorough eye examination by a Cataract Surgeon detects the presence and the extent of a cataract. Other conditions that could additionally compromise vision can also be detected, particularly problems involving the cornea, retina or the optic nerve.

Is Cataract surgery a must after diagnosis?

In the early stages, you can improve your vision by changing your glasses. But once the cataract progresses, changing glasses will not help. You will notice some deterioration in your ability to see things clearly from a distance. You may have difficulty with glare while driving, or while performing activities like reading that require clear vision. Other symptoms may be colored haloes, or double or multiple images in the eye when the other eye is occluded. In the early stages the timing of surgery is decided by the patient based on his visual requirements.  

How rapidly does a cataract mature?

A cataract may develop slowly over several years or rapidly within months. Often the other eye will also be affected, but it may not happen at the same time. There are no medications, eye drops, or dietary restrictions that can cure or prevent cataract formation. If the cataract interferes with your regular activities, the only solution is cataract surgery.

When Should Surgery Be Done?

Surgery should be considered when the cataract causes visual disturbance enough to interfere with daily activities. Based on these needs and the examination findings, the patient and the Cataract surgeon should decide together when surgery is appropriate. Cataracts need not to be mature ('ripe') before removal. Today cataract surgery has the means to remove both - an immature cataract and a mature ('ripe') cataract.

What Is Cataract Surgery?

In cataract operation your natural clouded lens is replaced by an artificial intraocular lens (IOL), which helps incoming light rays to be focused properly. Your new lens should restore vision to nearly what it was earlier, though you may need to wear glasses for reading or driving.

 Common misconceptions cleared:

·       Cataract is not a film over the surface of the eye

·       It is not caused by overusing the eyes

·       It is not infectious and will not spread from one eye to the other, nor is cataract a cancer

·       Cataract is not a cause of irreversible blindness                    

Surgical techniques:

Several techniques are used for removing cataracts.

• Phacoemulsification:

In this method a tiny instrument is inserted through a very small incision. The instrument uses ultrasound vibrations to break the cataract into fine pieces, which are gently suctioned out. The new lens is then inserted into the eye. Usually no stitches are required to close the incision. This minimal surgery allows faster and safer healing, hastening your return to normal activity.

• Small Incision Cataract Surgery (SICS):

This is a new technique where the cataract is removed manually through a small incision. The small incision heals fast, enabling you to recover quickly.

• Extracapsular extraction:

Here the lens is removed in a single piece through a relatively larger incision. It is replaced with an artificial lens and the incision is closed with fine stitches. The surgeon may opt for this technique in cases where the cataract is very advanced. The recovery period is longer here.

Your eye doctor will select the method of cataract operation that is most suitable for your case. 

The aqueous humour is the clear fluid circulating within and nourishing some parts of the eye which have no blood supply. 'Normal' individuals have an equal production and drainage of this fluid resulting in a constant pressure within the eye. If the drainage is compromised due to any reason, there is a pressure build-up in the eye, which can damage the optic nerve.                        

What Are The Different Types Of Glaucoma?

  • A Chronic open-angle glaucoma

Most common type of glaucoma; damages vision gradually and painlessly. The pressure is rarely high enough to be symptomatic.              

  • Angle-closure glaucoma

An acute attack of glaucoma caused by sudden blockage of the drainage channels leading to a sharp rise in pressure within the eye.

Symptoms include: 

·       Blurred vision

·       Severe eye pain, nausea and vomiting

·       Headache

·       Rainbow haloes around lights

·       Pain around your eyes after watching TV or after leaving a dark theatre

·       Red eyes

An acute attack requires the immediate attention of an eye doctor.

How Is Glaucoma Detected?

A Regular eye examinations by the ophthalmologist leads to detection.The complete and painless examination includes among other tests:

Tonometry - Measurement of the intraocular pressure [tension]

Gonioscopy - Inspection of the drainage angle of the eye

Ophthalmoscopy - Evaluation of optic nerve damage

Perimetry - Testing the visual field of each eye

 

Who Is At Risk For Glaucoma?

Everyone should be concerned about glaucoma and its effects. It is important for each of us, from infants to senior citizens, to have our eyes checked regularly, because early detection and treatment of glaucoma are the only ways to prevent vision impairment and blindness. There are a few conditions related to this disease that tend to put some people at greater risk.

This may apply to you if:

* Someone in your family has a history of glaucoma

* Age: If you are over 45 and have not had your eyes examined regularly

* Near-sightedness [myopia]

* Any injury to your eyes

* Secondary to other ocular conditions [cataract, inflammation, tumours etc.]

* Long-term medication [cortisone]

The main treatment for chronic glaucoma aims at reducing the pressure in your eye. Damage already caused by glaucoma cannot be reversed. Eye drops, tablets, laser and surgical operations are used to prevent or slow further damage from occurring. With any type of glaucoma periodic examinations are very important to prevent loss of vision. Because, glaucoma can irreversibly worsen without your being aware of it, your treatment may need to be changed from time to time during the periodic examination.

Medical treatment 

• Eye drops

When taken regularly and continuously as prescribed, they control the eye pressure either by slowing the formation of aqueous fluid within the eye or by increasing the flow at the drainage area. The proper technique of using your medication is a key to successful treatment. Our glaucoma clinic doctor or assistant will teach you the technique.

• Tablets

These are sometimes combined with the eye drops to decrease higher levels of eye pressure. They are occasionally known to cause tingling of fingers and toes, bowel irregularities, and in the very long term, kidney stones. Why a drug causes side effects in some persons and not others is not fully understood. By visiting the clinic regularly will help keep a check on what treatment suits you and its results.

• Laser surgery:

Lasers are usually used in one of three ways:         

  • In open-angle glaucoma the draining angle itself is enlarged to control eye pressure.
  • In angle-closure glaucoma the laser creates a hole in the iris to open up and improve the flow of aqueous fluid to the drain.
  • In painful late-stage glaucoma medication or surgery do not control the pressure. The laser closes some aqueous fluid-producing areas in the eye and lowers the eye pressure.

Operative surgery:

A new drainage channel is created for the aqueous fluid to leave the eye. Sometimes a tube drains the fluid in very resistant cases. Surgery is recommended when your doctor feels that it is safer to operate than to allow optic nerve damage to continue. The best treatment for you should be decided after a thorough examination and discussion with us.

Our centre at Leela Eye Institute runs Glaucoma Clinics for the special purpose of preserving sight in sight-threatening conditions such as glaucoma.

The patient receives specialized care provided by our glaucoma specialists

Glaucoma needs regular follow-up since the condition can cause asymptomatic and irreversible loss of vision if poorly treated or neglected

The effect of your treatment on the eye pressure may not always be constant and needs to be regularly measured by our glaucoma specialist.

At the clinic we record images and maintain records of your eye condition for comparison on following visits.

What Is Your Part In The Treatment?

Treatment requires a team effort [you and the doctor]:

The prescription must never be altered or stopped without consulting your doctor. Frequent eye examinations and tests are critical to monitor your eyes for any changes. 

How Do I Minimize The Risk Of Getting Glaucoma?

You need an eye examination -          

Every 18 - 24 months if you are age 39 years or over,

Every 12 months if a family member has glaucoma, if you have had a serious eye injury in the past, or if you are taking steroid medication [tablets or eye drops]. The Glaucoma Clinic has an early diagnosis centre keeping in mind the higher risk for glaucoma among family members.

Eye Care

Eye drops should be applied correctly to be of maximum benefit. Consult your doctor for correct administration of drops.

Q.    Is glaucoma curable?     

A.     Glaucoma is not curable, but it is manageable usually with simple medications such as eye drops and pills.      

                 

Q.    Which age groups are most affected?   

A.     All age groups are at risk for glaucoma, though elderly persons above the age of 60 years are more at risk.  

                 

Q.    Does glaucoma cause blindness? 

A.     If left untreated, glaucoma can cause blindness. About 10% of patients with glaucoma who receive proper treatment may still have loss of vision. Loss of vision from glaucoma is irreversible.

                 

Q.    How can I protect myself against the damage that glaucoma can cause?   

A.     You can protect yourself from loss of vision due to glaucoma through regular eye examinations, taking your medication as prescribed and good eye care.

                 

Q.    What is the role of surgery?   

A.     Surgery is done when medications are not effective or they cause intolerable adverse effects. Surgery is effective in relieving glaucoma, but the condition can recur even after surgery.    

                 

Q.    Will glaucoma affect my work?      

A.     Many people have productive lives despite having glaucoma. Ensure good lighting at the work place and get magnification of texts if needed. Maintain good communication with your employer / supervisor. Above all, be positive!

Now you can lose your glasses.... on purpose!!

Remember how your life changed when you had to get glasses? Now you can change it back and see naturally again. All this is possible now thanks to laser vision correction. We know you need more information to make an informed decision; so we would like to answer some of the questions you may have while considering this procedure.

 

What Is Lasik?

Laser Assisted Stromal In-situ Keratomileusis [LASIK] is a method of re-shaping the external surface of the eye [the cornea] to correct low, moderate and high degrees of nearsightedness, astigmatism and far-sightedness. During the treatment, an instrument called the microkeratome creates a corneal flap to make it a painless procedure.

The computerized Excimer laser then uses a cool beam of light to gently reshape the cornea so as to alter its curvature to the desired extent. The flap when replaced on the new corneal curvature allows images to be sharply focused on the retina. The goal is to eliminate or greatly reduce the dependence on glasses or contact lenses.

Who Is A Candidate?

The treatment is for patients who have a refractive error and meet certain visual and medical criteria. In addition the best candidates tend to be those who are dissatisfied with their contact lenses or glasses and are motivated to make a change, whether it is due to occupational or lifestyle reasons. However, only a thorough examination by our LASIK 

Q: Is Lasik Safe?

A: Yes. When choosing this method to improve your vision safety should be your first concern. It's ours too. New generation Excimer lasers and advances in technique offer the highest degree of accuracy and utmost safety. Recent studies conducted internationally and by us show it to be a very safe and effective procedure.

 

Q: Is Lasik Successful?

A: Yes. LASIK is a permanent treatment. However, patients who are 40 years and above may require reading glasses. Millions of patients worldwide and thousands at our centre have had an Excimer laser refractive procedure done on them successfully. During your consultation we will give you an idea of the procedure and the level of vision you can expect.

 

Q: Are There Other Refractive Procedures?

A: You may have heard about PRK [photo refractive keratectomy]. You may have also heard about the surgery known as RK [radial keratotomy]. You need to understand that these are two completely different procedures from LASIK with less predictable results.

 

Q: Is This The Latest Technology?

A: The latest and most reliable procedure is wavefront-guided LASIK, a customized treatment for each eye. Our excimer lasers use high-speed sensitive eye trackers to ensure perfectly centered treatments. Wavefront procedures even often leave patients with eyesight better than normal. We are committed to providing our patients with the best that technology and technique has to offer.

 

Q: How Soon Can I Return To Work after Lasik?

A: You will notice an improvement in vision within 4-6 hours and a restoration of functional vision by the next morning. However, complete recovery may take up to 48 hours. Some people get back to work the day after treatment. Two or three days are suggested.

Eye has a small drainage apparatus in the medial side between nose bridge and the eye called Lacrimal sac. It has two canaliculi that drain excess tears and eye drops from the eye in to the lacrimal sac and then in to nose through a nasolacrimal duct. It is due to this system that some people experience drops instilled in eye entering in the throat.

Acute Dacryocystistis:

Any blockage in this Drainage system causes excess tears to flow out of eyes causing watering. Due to stagnation of fluid in the lacrimal sac it can get infected causing severe pain, redness and swelling around the eye. This condition is called as Acute Dacryocystistis which can keep on recurring time and again.

Endoscopic Dacryocystorhynostomy Surgery:

Endoscopic Dacryocystorhynostomy Surgery is a solution to problem. In this surgery a by-pass is created with endoscope that results in drainage of the tears in nose directly.

Kindly consult your eye doctor for details.

The Cornea:

The cornea is the front, outmost layer of the eye. Just as a window lets light into a room, the cornea lets light into a room, the cornea lets light into the eye. It also focuses the light passing through it to make images clear and sharp.

 

Corneal Problems:

Corneal problems can happen to anyone at any age. Sometimes due to disease, injury or infection the cornea comes cloudy or warped. A damaged cornea, like a stained or misshapen windowpane, distorts light as it enters the eye. This not only causes distortion in vision, it may also cause pain.

When there is no other remedy, doctors advise a corneal transplant. In this procedure, an ophthalmologist surgically replaces the diseased cornea with a healthy one to restore clear vision.

 

What is Corneal Transplant?

Transplant is the replacement of damaged or diseased tissues or organs with healthy tissues or organs. In a corneal Transplant, the cloudy or warped cornea is replaced with a healthy cornea. If the new cornea heals without problems, there may be tremendous improvement in vision.

The healthy corneal tissue used for transplantation is supplied by an Eye Bank. Eye Banks work round the clock collect, evaluate, and store donated corneas. The corneas are collected from human donors within hours of death. Stringent tests are done to ensure the safety of the person receiving the cornea. The Eye Bank verifies the donor's medical history and cause of death, and performs blood tests to ensure that the deceased person did not have any contagious disease, such as AIDS or hepatitis.

Once the cornea was one of the first parts of the body to be transplanted, corneal transplants remain one of the most common, and most successful, of all transplants.

The potential risks

As with other surgical procedures, a corneal transplant involves some risks - most of them can be treated. Some possible complications are:

Eye infections

Failure of the donor cornea to function normally

Rejection of the donor cornea by your body

Cataract (clouding of the eye's lens)

Glaucoma (build-up of fluid, leading to increased pressure in the eye)

Bleeding from the iris

Swelling or detachment of the retina

Contact Lenses are simple to wear and care for, and are almost undetectable. They are thin discs of plastic, curved on the inside to fit properly onto the surface of the eye, and shaped on the outside to correct and improve defective vision, for bandaging the eye after surgery, and cosmetic benefits e.g. to cover white scarring of the eye or to change the colour of the eye for fashion. With advancing technology Contact Lenses can correct all forms of visual defects including Astigmatism safely and comfortably.

Types Of Contact Lenses

There are basically two types of contact lenses: Rigid and Soft. Both types come in varying materials with different levels of oxygen permeabilities. The higher the oxygen permeability the better it is for the eye. The recent trend in contact lens wear has shifted to soft lenses with rigid lenses advised only in special circumstances like keratoconus.

With major advances in materials, millions of people have discovered that contact lenses are a safe, comfortable, convenient and affordable alternative to spectacles. Contact lenses are thin, domed discs made of complex plastic materials, and are positioned in front of the transparent outer layer of the eye called the cornea, to focus images onto the retina at the back of the eye. There are basically two types of lenses:

Rigid Gas Permeable (RGP):

RGP lenses are semi-rigid lenses made usually from acrylate and fluorosilicon, a plastic which allow oxygen through to the eye. They are clinically the best as they allow maximum oxygen to reach the cornea being smaller in size. They are easy to care for, durable and give good clarity of vision. They can be prescribed for all types of vision correction, including high astigmatism, bifocals, post surgery (RK, PRK, & Lasik), therapeutic, and cosmetic for all age groups. In certain cases these lenses are also prescribed for myopia control.

Soft lenses:

Soft lenses are made from water-absorbing plastics, which make them pliable and membrane-like for maximum comfort. They are ideal for sports as they cannot be easily dislodged from the eye.

Important points to remember:

All types of contact lenses should always be kept clean, disinfected and hydrated. Lens hygiene is the key to a comfortable wear. All contact lenses accumulate a variety of deposits, from the eye itself whilst wearing them, and from the environment:

  • The tears of the eye contain proteins, lipids (oily secretions), mucous and calcium.
  • The environment also contributes towards building up of these deposits especially on soft lenses.
  • The chemical pollution from cars, factories etc., dust, metal in the air get embedded onto the surface, causing harmful contamination on the lens surface, over a period of time.

In order to prevent these deposits, all contact lenses should be cleaned, soaked and disinfected daily.

When should I replace my contact lenses?

A new system of prescribing and manufacturing contact lenses has been introduced now in India – Frequent Replacement – which enables the replacement of lenses on Daily, Weekly, Monthly, and Three Monthly basis.

The advantages of this system of prescribing is that, frequent infections due to protein deposits and environmental pollution are almost eliminated, the eye gets more Oxygen, Vision and Comfort are greatly increased, and best of all, simple cleaning systems like multipurpose solutions can be used safely.

All types of soft contact lenses get contaminated within 24 hours (when not in the eye), due to the water contained in the material. To prevent this from happening they should be disinfected daily.

How should I clean my Contact Lenses?

Hypoallergenic solutions formulated for sensitive eyes are the best and safest for the eyes. Daily cleaning by rubbing in the palm of the hand with a surfactant cleaner is important, as well as the weekly protein cleaning, to prevent infections due to lens contamination.

A good contact lens specialist will spend time to properly educate the patient regarding the cleaning and disinfection of their lenses and have at their disposal proper instruments for fitting and supply of contact lenses. It is this combination of good advice and service that makes it possible to adapt to contact lenses successfully and safely.

Always take advice from a properly qualified contact lens specialist to tell you which lenses are suitable for your eyes after examining them thoroughly.

Q.    Can anyone wear contact lenses? 

A.     Millions of people across the world do. And 96% of patients fitted with contact lens find them a complete success. Chances are, you'll be able to wear them comfortably and happily, almost indefinitely. In the very unlikely event of your eyes being unsuitable, your contact lens Practitioner will tell you, and explain why.      

                 

Q.    Are contact lenses visible to others while I am wearing them?      

A.     No. Modern technology has meant that contact lenses are very thin and sit discreetly on the eye. 

                 

Q.    Are there any disadvantages to wearing contact lens? 

A.     It will probably take a few weeks to get used to wearing contact lens, but it is worthwhile to persevere! CONTACT LENS CLINIC will always help you with your queries and problems. Your contact lenses" must be cleaned carefully everyday so you should get into a regular routine of looking after them. You may sometimes experience temporary discomfort with your lenses in smoky, dusty, windy or some air-conditioned atmospheres. Generally you will be unable to feel your lenses in place once you are accustomed to wearing them.

Remember: Routine checks at the intervals recommended by your Contact Lens Practitioner are essential to long term success with contact lenses & healthy eyes. Regular replacement of lenses and scrupulous attention to cleaning is essential.   

                 

Q.    Can anyone of any age wear contact lenses?       

A.     Yes. Whether you're young or old, you can probably wear lenses successfully. In children contact lenses can be worn as soon as they are responsible to handle them carefully.    

                 

Q.    Are there people who can't wear contact lenses?  

A.     Some rare conditions might prevent you from wearing contact lenses successfully. If you have a reduced tear flow, your eyes may be too dry for contact lenses to be worn comfortably. Your eyes & lids may be too sensitive if you suffer from certain allergies. However, very few people do not succeed with contact lenses.   

                 

 

                 

 

Q.    Are contact lenses safe for sports?

A.     Contact lenses are excellent for sport. They give you an unrestricted view, won't mist over when you get hot, or get smeared with raindrops when it's wet, and they can't be knocked off your face and broken. Discuss your sporting activity at you contact lens consultation to help decide the best type for you. For example, soft lenses may be best for those who participate in active sport egg tennis, riding, cricket, football, rugby or squash, as they are unlikely to become dislodged. Contact lenses are not recommended for swimming without a well-fitting mask or goggles. 

                 

Q.    Can I still wear eye make-up?

A      Yes. In fact, many people find it easier to apply their make-up wearing contact lens - because they can see exactly what they are doing! You should put in the lenses first so you can see clearly & so you don't get eye make-up on them while inserting.

It is best to avoid powdery & metallic shadows, or mascara with fibers, in case particles get onto your lenses. You should also take your lenses off before removing make-up & avoid using greasy cleansers. Several brands of eye make-up have been specially developed for contact lens wearers & for people with sensitive eyes.      

                 

Q.    Is cleaning important? Do I need to clean my lenses even if I change them every month?

A.     It's essential to clean your lenses every day to avoid deposits accumulating & this keeps your contact lenses clear & comfortable. Cleaning also helps to prevent the risk of infection.

Yes. It's just as important to clean your frequent replacement contact lenses every day. Deposits can begin to build up after only a short period of wear & will need to be removed daily.

                 

Q.    My eyes are astigmatic - can I wear contact lenses      

A.     Yes. In most cases astigmatism is a condition where the surface of the eye is an irregular shape, so the image is distorted onto 2 separate points of focus on the back of the eye. Depending on the degree of your astigmatism, your contact lens Practitioner will advise either soft, gas permeable or toric lenses.

 

Q.    Are contact lenses safe to wear?   

A.     Your eyes are ten times more sensitive than the rest of your body & the tissues in & around your eyes are delicate & unique. So it is very imp. That you are scrupulous about hygiene when handling your lenses, & that you clean them thoroughly & properly using the care regime recommended by your contact lens Practitioner.

Some people are particularly prone to eye infections & they may be wise to give up contact lenses & return to spectacles on the advice of their contact lens Practitioner. Serious problems associated with wearing contact lens are extremely rare, usually as a result of inadequate contact lens hygiene.
