The cornea is the clear front dome shaped window of the eye. It provides about 2/3 of the eye's focusing power. It gives us a clear window to look through and is the key to good vision. It also helps shield the rest of the eye from germs, dust, and other harmful pollutants.
The Corneal Service at our centre delivers medical and surgical care to a wide variety of corneal, external eye related diseases and anterior segment eye disorders.
The Service is managed by a trained corneal sub-specialist ophthalmologist.
Some of the problems dealt with are:
1. OCULAR SURFACE DISORDERS: Diseases affecting the ocular surface result in non-specific symptoms and can range from a tired or itching eye to diminished vision in severe cases.

Surgical facilities offered by the cornea service:
- Cornea transplantation which involves replacing a diseased or scarred cornea with a new one. In corneal transplant surgery the surgeon removes the central portion of the cloudy cornea and replaces it with a clear cornea. The chances of success of this operation have risen dramatically because of technological advances. Corneal transplantation has restored sight to many, who a generation ago would have been blinded permanently by corneal injury, infection, or inherited corneal diseases or degeneration. Recent modified forms of corneal transplant called Lamellar Keratoplasty are also performed. This involves removing only the partial thickness of the cornea that is diseased leaving the rest of the healthy cornea undisturbed. Lamellar Keratoplasty is of two types: Deep anterior lamellar Keratoplasty (DALK) and Deep lamellar endothelial keratoplasty (DLEK)
- LASIK
LASIK, an acronym for Laser-assisted In Situ Keratomileusis, is a form of refractive laser eye surgery procedure performed by cornea specialists as an alternative for people wearing glasses and contact lenses. - PRK
Photo Refractive Keratectomy is an excellent alternative to LASIK in selective cases where LASIK cannot be performed due to safety considerations as corneal thickness may be inadequate. - PTK
Photo therapeutic Keratectomy is an excimer laser based therapeutic surgery done for numerous conditions ranging from corneal dystrophies to recurrent corneal erosions. It not only improves vision but also brings relief from recurrent episodes of painful red eye and also helps to delay the need for cornea transplantation.
