Introduction: In many case Pterygium is found to causeastigmatism. Study aimed to find the effect of pterygiumexcision on keratomerty readings.Material and Methods: The present Retrospective study wasdone on 50 eyes of 50 patients, who had primary pterygiumand underwent pterygium surgery during period of October2016 to October 2017 in a tertiary care hospital. Informationthat was reviewed included preoperative uncorrected and bestcorrected visual acuity, auto refraction, auto keratometry anddetailed anterior segment and posterior segment examination.Results: Mean astigmatism changed from preoperative 5.94 ±3.82 Diopters (D) to 1.30 ± 1.07 D on 30th post operative dayshowing 4.64 ± 2.75 D of change in astigmatism.Conclusion: Pterygium can be a cause of low vision secondaryto corneal astigmatism. Pterygium excision reduces cornealastigmatism significantly, which improves vision.
