EVALUATION OF EFFECT OF CORNEAL COLLAGEN CROSS LINKING FOR KERATOCONUS ON CORNEAL TOPOGRAPHY

Abstract

Keratoconus is a condition in which the cornea assumes a conical shape as a result of non-inflammatory thinning of the corneal stroma. The corneal thinning induces irregular astigmatism, myopia, and protrusion, leading to mild to marked impairment in the quality of vision. It is a progressive disorder ultimately affecting both eyes, although only one eye may be affected initially. Corneal collagen crosslinking (CXL) is a technique which use UV light and photosensitizer to strengthen chemical bonds in the cornea. The aim of this study was to study the changes in corneal topographic indices
after CXL for Keratoconus.
