Abstract
Background: Keratoconus is an asymmetric, non- inflammatory, and progressive ectasia of the cornea that is
characterized by the thinning, steepening, and central scarring of the cornea. Corneal collagen cross linking with
riboflavin and ultraviolet light is an accepted procedure to stabilize keratoconus. This study is aimed at finding out
keratometric changes after corneal collagen cross linking. Methods: A total of 30 patients were enrolled, 15 males and
15 females. They were subjected to corneal topography, refraction, slit lamp examination, preoperatively and post
operatively at 1 month 3rd moth and 6th month after corneal collagen cross linking. Results: Flattening of Keratometry
values were noticed in 12 eyes (40%). The mean pre-operative K was 50.32 D. The mean post-operative K was 49.61
D. In 5 eyes (16.66%) the corneal curvature was unchanged and stable. Conclusion: There is significant decrease in
mean keratometric values and flattening of cornea after corneal collagen cross linking.
