Cornea & Refractive


the cornea is the transparent front part of the eye . The cornea, accounts to approximately two-thirds of the eye’s total optical power. In humans, the refractive power of the cornea is approximately 43 dioptres. Any injury or infection of the cornea can lead to damage leading to loss of corneal transparency and thereby disrupting the normal vision.

What all conditions occur in cornea?

Diseases affecting the cornea are a major cause of blindness all over the world. This is called Corneal Blindness. A range of infectious and inflammatory eye conditions ultimately affect the transparency of the cornea leading to corneal blindness. The significant conditions seen in this clinic are corneal ulcers, keratitis, corneal dystrophies, opacities, PK cornea graft rejection etc.
