Corneal Collagen Cross linking with Riboflavin and UVA light for keratoconus: One year results in Indian eyes

Abstract
AIM: To assess the results of Corneal Collagen Cross linking with Riboflavin using Ultraviolet – A light for keratoconus at one year in Indian eyes.
METHODS: Sixty eight eyes of 41 patients with progressive keratoconus were included in this retrospective study. All eyes completed six months of follow up and 37 eyes had a one year of follow up. The maximum follow-up was 16 months. Ocular examinations including refraction, best corrected visual acuity (BCVA), corneal topography, were recorded at each visit.
Results: The preoperative values on the day of treatment were compared with postoperative values of the 12 month examination. This showed that BCVA improved at least 1 line in 54% of eyes and remained stable in 28% of eyes Astigmatism decreased by a mean of 1.20Din 47% of eyes and remained stable (within ± 0.50 D) in 42% of eyes.
CONCLUSION: The results show a stabilization and improvement after collagen cross linking in Indian eyes. This suggests that it is an effective treatment for progressive keratoconus.

What is difference between keratoconus and "common" astigmatism and what do the numbers mean?

Astigmatism is a common condition where the curvature of one or more of the optical surfaces of the eye (the cornea and lens surfaces) are more "round" in one direction than the other. In "regular" astigmatism the maximum and minimum powers are aligned at 90 degrees to each other while in "irregular" astigmatism they do not align. An egg is a good example of a surface with "regular astigmatism". Keratoconus is a degenerative condition where the cornea thins in affected areas. This can lead to astigmatism - often regular at first but becoming increasingly irregular as the disease progresses.
