CORNEAL TOPOGRAPHY

Corneal topography is a method of examining the corneal curvature assisted by computer analysis. A topography machine projects a series of illuminated rings onto the corneal surface, after which a photographic image is taken and is analysed by the computer; this image is generated through a special software.

The digital image is colour-coded (the steeper areas are represented by warm colours such as red, while the relatively flatter areas are in cooler colours such as blue – green) to show the curvature of the cornea in different areas, just like an aerial view of a landscape. It is the equivalent of taking a fingerprint. The information obtained from a Topograph is very useful and essential in planning the treatment for LASIK.

Doctor Eye Institute has been one of the first in India to implement corneal topography machine to provide the best of the services in total eye care to all its patients.
