Comparision Between Suture Technique And Sutureless/ Glueless Pterygium Surgery Performed With Conjuncival Autograft

PURPOSE : 1. TO COMPARE THE SAFETY AND EFFICACY OF THE TECHNIQUES

2. TO STUDY THE CHANGE IN ASTIGMATISM BEFORE AND AFTER THE SURGERY

TERTIARY LEVEL INSTITUTE

The study was carried out on 42 patients with primary Pterygium. The subjects were randomised to undergo Pterygium surgery using either suture less/glue less (21 eyes) or suture (8-0 silk) technique to attach the conjunctival auto graft. . Patients were followed up after 48 hours, 1 week, 2 weeks a 6 weeks and 3month post operatively.

Mean astigmatism pre-operatively was 4.26±3.18D in eyes treated with suture less/glue less technique which subsequently decreased to 1.03±0.66 D. Mean astigmatism pre-operatively was 4.98±3.48 in eyes treated with sutured technique which subsequently decreased to 1.26±0.84 D. The change in the astigmatism was statistically significant (paired t-test, p<0.05). Mean surgical time was 15.40±1.47 minutes in suture less/glue less technique and 27.83±1.82 minutes in suture technique to attach the conjunctival auto graft. 

Conjunctival auto graft with suture less/glue less technique is as safe as conjunctival auto graft with suture technique.  Suture less/glue less technique reduces the surgery time with successful adherence of the auto graft and improves post operative comfort.
