Abstract
Objective: To evaluate the effect of pterygium excision on pterygium induced corneal astigmatism
Methods: Hospital based study conducted in a tertiary care centre in Western Maharashtra from August 2014 to March 2015. A detailed evaluation of the pre and post-operative status of patients was done. 40 patients underwent pterygium excision with conjunctival autograft.
Results: Most of the patients belonged from 41-45 years of age group i.e 42.5% (17 patients). 52.5% (21) patients had grade II pterygium and 37.5 %( 15) patients had grade III pterygium. Pterygium excision showed a significant decrease in amount of corneal astigmatism post operatively as well as improvement in visual acuity (mean ± SD).
Conclusion: This study verifies that pterygium excision with conjunctival autograft can result in significant decrease in corneal astigmatism and thus improve visual acuity of patients post operatively.
