The influence of pterygium on corneal astigmatism

Dr G. Suneetha, Dr G. Hanumantha Rao

Abstract :

Aim: To study the influence of progressive pterygium on corneal astigmatism and it’s modification by excision and amniotic memane grafting. Methods: This was a prospective interventional case series of 31 patients with progressive pterygium treated at Ophthalmology Department of a tertiary center between January 2018 to June 2018. Every patient was subjected to a thorough clinical evaluation. Corneal astigmatism was measured with a Keratometer before and after surgery. Surgery performed was pterygium excision and amniotic memane grafting. Results: The average preoperative corneal astigmatism was 2.1D (grade 1 – 0.9D and grade 2 – 3.06D) The average postoperative corneal astigmatism was 1.04D (grade 1 – 0.73D and grade 2 – 1.8D). The astigmatism was more with higher grades of pterygium. Conclusions: Pterygium induced significant corneal astigmatism was proportional to the area of corneal involvement which was modified by pterygium removal and amniotic memane grafting.
