Abstract

Introduction: This paper aimed to determine the corneal stabilization point utilizing corneal topographic approach subsequent to pterygium excision using controlled partial avulsion fibrin glue technique. Methods: Ninety-three eyes of 93 patients who had undergone primary pterygium excision surgery were retrospectively reviewed. Topographic changes were determined by having four (4) follow-up sessions (at 1st, 3rd, 6th, and 12th month post-surgical based on changes in Simulated-K (SimK). The parameter studied was the degree magnitude of astigmatism measured by Zeiss ATLAS 995 corneal topographer. Three measurements were taken and the measurement with the best image quality was taken as the measurement value. These measurements were done by single operator and performed on the same visit. All participants then undergo pterygium excision performed by a consultant ophthalmologist (KMK). RM-ANOVA and Bonferroni post-hoc analysis were employed to evaluate the difference between sessions with SimK. Results: Topographic changes revealed corneal stabilization point at 3rd month post-operatively. Significance improvements for corneal astigmatism was noted for the 1st and the 3rd months (both P < 0.001), followed by insignificant changes towards the remaining 6th and 12th months visits (both P > 0.05). Conclusions: Anterior corneal curvature stabilization point at 3rd months of post-surgical procedure. Thus we suggest other refractive procedures are safe to be performed after the 3rd month of pterygium excision.
