Effect of Pterygium Excision on Pterygium Induced Astigmatism and Visual Acuity

Abstract

Pterygium excision is indicated if it is progressive, visual axis is threatened; diplopia is induced due to extreme fibrosis, prior to LASIK. Early surgical intervention can, therefore, reduce effects of corneal morbidity due to pterygium induced corneal distortion and visual disturbance arising from the encroachment of the pterygium into the visual axis. Early or late surgical intervention for excision of pterygium surgery leads to reduction in astigmatism, which leads to significant improvement in vision.9,10 This study was carried out to evaluate the corneal astigmatism before and after pterygium excision. Objective To evaluate the effect of pterygium excision on the pterygium induced astigmatism.
