Abstract
Introduction: Pterygium is a triangular-shaped, degenerative mass growing from the conjunctiva to the cornea, which leads to corneal astigmatism or impairs vision if grows to the pupillary area. Reduction in astigmatic changes can be seen after the excision of pterygium and conjunctival autograft.
Aim: To study the changes in refractive errors in the case of pterygium excision with conjunctival autograft.
Materials And Methods: The prospective, hospital-based, analytical study was conducted in the upgraded department of ophthalmology in GMC, JAMMU for a period of one year from July 2021 to June 2022. All the cases operated during this period were included in the study.
Observations And Results: A total of 112 patients were operated. Out of 112 patients, 68 were males and 44 were females. The mean age of presentation was 48.19 years. Following surgery, the mean astigmatic value decreased from 1.108929± 0.346619 to 0.826339 ±0.354378and the change in astigmatism (0.282143 ±0.101088) was statistically significant (p < 0.001, paired t-test).
Conclusion: A change in refractive error reveals corneal flattening due to Pterygium. The improvement in refractive error can be used as one of the indicators of the success of Pterygium surgery.
