Abstract

INTRODUCTION: Pterygium is a common ocular surface disorder characterized by a fibrovascular growth extending onto the cornea, often leading to visual impairment through induced astigmatism and corneal distortion. Surgical excision is the primary treatment, with Amniotic Membrane Grafts (AMG) and Conjunctival Autografts (CAG) being the prevalent techniques. This study aims to compare the autorefractive changes post-pterygium excision using AMG versus CAG. MATERIALS AND METHODS: This prospective comparative study included 25 eyes from 25 patients with nasal pterygium, who underwent excision surgery at the Sree Mookambika Institute of Medical Sciences between July 2022 and December 2023. Patients were divided into two groups: 13 underwent AMG and 12 underwent CAG. Preoperative and postoperative assessments included Best Corrected Visual Acuity (BCVA), autorefractometry, pachymetry, and anterior segment examination. Statistical analysis was performed using the Student t-test, with significance set at p < 0.05.
