Frequently Asked Question

The cornea is the clear, dome-shaped surface that covers the front of the eye

It is the wound in the cornea due to trauma or infection.

Keratoconus is a progressive disease in which the normally round cornea thins and begins to bulge into a cone-like shape. This cone shape deflects light as it enters the eye causing distorted vision.

Collagen fibers help hold the cornea in place and keep it from bulging. When these fibers become weak the cornea becomes progressively more cone shaped.

By slit-lamp examination corneal thinning can be observed. Corneal topography is also useful in detecting early keratoconus and allows following its progression.

Mild form of keratoconuscan be corrected byeyeglasses orRGP contact lenses. But severe forms cannot be corrected by them.

C3R stands for CORNEAL COLLAGEN CROSSLINKING with riboflavin C3R is a keratoconus treatment.

It depends on the nature of condition,C3R helps to control the progress but cannot cure them completely .close follow up is required .

The most common airborne allergens that cause eye allergies are pollen, mold, dust and pet dander.Eye allergies also can be caused by reactions to certain cosmetics or eye drops that contain preservatives.It may be seasonal or perennial.

Eye allergy can be prevented by avoiding exposure to common allergens by wearing sun goggles while going outside during allergy season, avoiding contact with pets and avoid using cosmetics and drops causing allergy.

Prevention is always better than cure. The first approach in managing eye allergy is to avoid allergens.

Stay indoors when allergens are at peak

Wear sunglasses when going out

Avoid rubbing eyes as this might worsen the symptoms

Keep windows closed and use ac at home

Wash bed sheets frequently in hot water

Mop the floors rather than dust sweeping

Avoid contact with pets

Washing hands often especially before and after touching eyes

Artificial tears: help to wash out the debris and lubricate the eyes.

Decongestants: help reduce the redness. Not suitable for prolonged use since they cause rebound congestion.

Anti-histamines : help reduce itching.

Mast cell stabilizers: used to prevent allergy.

Corticosteroids: used in the case of severe allergy.

Immunotherapy : if they are non-responsive to steroids then immune modulators are given.

Eye infection is caused by a virus or bacteria, the infected person can be contagious for several days to several weeks once symptoms (itchy, watery eyes; with or without eye discharge) appear.

If the infection is caused by a common viral infection and no other complications occur, then your eyes should clear up within a few days to two weeks.

Infection also can be caused by bacterial conjunctivitis, which — even with treatment such as prescription antibiotic eye drops — can last up to a month or longer. However, with this type of infection, people should no longer be contagious 24 hours after antibiotic treatment begins.

No ,infection is contagious .it is preferable to stay indoor as it may spread to other kids in school.

During infection your cornea( transparent part in front ) is affected which makes you more sensitive to bright light .it will be difficult for you to face bright light especially while driving .Its better to avoid outdoor activities or wear a sunglasses to avoid discomfort .

No, infection is caused by many organisms like bacteria ,virus , fungal . all commonly show redness symptoms but treatment and selection of eye drops differ for each case.seek your doctor advice and use drops according to prescription.

No,due to infection your cornea may be affected deeply . It takes time to heal and restore the normal vision back .consult your cornea specialist in case of doubt and emergency .

Cornea, is the clear front surface of the eye which allows light to enter the eye. Vision could be markedly reduced or lost if the cornea becomes cloudy or scarred. This is known as corneal blindness.

A corneal transplant is a surgical procedure to replace part of your cornea with corneal tissue from a donor. The cornea is the transparent, dome-shaped surface of your eye. This surface is responsible for focusing light much like the lens of a camera. The cornea must be clear and regular because it accounts for a large part of your eye’s focusing power.

Corneas are sourced from regional “eye banks.” The donor tissue is rigorously inspected for suitability and safety.

Transplants may be performed to restore vision by replacing scarred, diseased or physically distorted corneal tissue with clear, non-distorted healthy tissue. Often times, these are typically caused by Keratoconus, trauma or infections.

Corneal rejection is uncommon. Rarely, a loss of transparency occurs due to rejection or repeated eye surgeries. If this occurs, another procedure may be performed at the discretion of your surgeon.

Most corneal transplants last well beyond 10 years. Corneal transplant patients require bi-annual ophthalmic checkups to ensure optimal eye health.

This varies from patient to patient, contingent upon the surgical technique employed to execute the procedure and achievable pre-operative vision.

The new femtosecond laser technique (IEK), offers most patients the ability to achieve vision for limited function, without contacts or glasses, within 2 to 3 weeks.

At 6 to 7 months after surgery, when some or all of the sutures have been removed, most patients may achieve 20/40 or better vision with glasses or contacts.

The non-laser technique has a much longer recovery period. A similar outcome may be achieved at 12-18 months.

This varies from patient to patient. In general, it is safe to resume normal non-contact physical activities, like gym, yoga, etc., within 1 month.

No, your eye color stays exactly the same. The transplant involves only the transparent clear cornea and not the colored part of the eye (iris).
