Abstract: Study of changes in visual acuity and keratometric readings after pterygium excision surgery; PURPOSE: to study changes astigmatism after pterygium excision surgery. MATERIALS AND METHODS: a prospective observational study carried out on 50 patients having primary pterygium admitted in ophthalmology department, P. D. U. hospital Rajkot; 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 cha changes in 54 % of patients. ; COCLUSION: 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 significantly.
