Dr. Vimal J Vyas | Dr. Pooja S Chandarana ^[2]

Abstract: Study of visual acuity and keratometric changes after pterygium excision surgery; PURPOSE: to study changes in visual acuity after pterygium excision surgery. ; MATERIALS AND METHODS: a prospective intervational case study carried out on 50 patients having primary pterygium; ; RESULT: pterygium excision surgery improved corneal astigmatism from 2-10 D pre operatively to 0.50 -3 D post operatively with improvement in visual acuity of 4 lines of snellens acuity chart in 36 % of patients and 3 lines of snellens acuity chart changes in 54 % of patients. ; CONCLUSION: Pterygium leads to significant high corneal astigmatism, which hampers vision of the patient. Excision of pterygium leads to statistically significant reduction in astigmatism, which improves vision.
