Comparison Of Keratometric Readings Pre and Post Pterygium Excision With Conjunctival Autograft Transplantation

Sponsor: Mughal Eye Trust Hospital

Summary

Pterygium, often called "surfer's eye," is a common eye condition in which a raised, fleshy growth of tissue extends from the white part of the eye onto the clear cornea. This growth can cause redness, irritation, blurred vision, and, in advanced cases, changes in the curvature of the cornea leading to distorted vision (astigmatism). The condition is more frequent in people exposed to sunlight, dust, and dry environments. The standard treatment for symptomatic pterygium is surgical removal. However, simple removal has a high chance of recurrence. To reduce this risk, surgeons commonly use a technique called conjunctival autograft transplantation, where a small piece of the patient's own conjunctiva is placed over the area after excision. This method not only lowers the recurrence rate but may also improve vision by reducing corneal irregularities. This study is designed to measure the changes in corneal curvature (keratometric readings) before and after pterygium excision with conjunctival autograft transplantation. By comparing preoperative and postoperative measurements, the study aims to determine how much this surgery improves corneal shape and reduces astigmatism. The hypothesis is that pterygium excision with conjunctival autograft transplantation will lead to a significant improvement in keratometric readings and reduce irregular astigmatism, thereby improving visual quality. This research will provide local evidence of the effectiveness of this procedure and help guide treatment strategies for patients suffering from pterygium-related visual problems.
