Best Cornea Specialist in Delhi
When light strikes the cornea, it refracts the incoming light onto the lens which subsequently refocuses that light onto the retina that enables the translation of light into vision. The normal corneal surface is smooth and aspheric, which means it is round in the centre, flattening towards its outer edges. Therefore, as light rays pass through cornea, it moves in an undistorted manner to the retina to project a clear image to the brain. But, in patients with Keratoconus, a bilateral ocular disorder, the cornea becomes rounded-cone-shaped due to progressive thinning of the cornea, and its surface becomes irregular. Because of this abnormal curvature, the cornea’s refractive power gets affected which results into moderate to severe distortion (astigmatism) and blurriness (nearsightedness) of vision.
Keratoconus, which usually affects both eyes may cause swelling and scarring of the tissue that leads to permanent loss of vision in a few cases. But, in most cases, it can cause partial loss of vision or visual distortion.
Keratoconus, derived from Greek word “kerato” for cornea and “conus” for cone, classically has its onset at puberty and is progressive until the third or fourth decade of life when it usually arrests.

Keratoconus can be detected clinically by Slit Lamp Examination and the diagnosis can be confirmed by Corneal Topography. Hitech eye centre boast of a coveted team of top surgeons who are the best cornea specialists in Delhi for Corneal Treatments and Transplantation Surgery.
