Comparative study of pterygium surgery by conjunctival advancement flap with sutures versus graft on autologous serum

Abstract

Aim: To compare the surgical outcomes of pterygium by conjunctival advancement flap with sutures versus graft on autologous serum in terms of g raft stability, post operative inflammation and recurrence. Materials and Methods: A prospective study to compare and analyze 114 cases of pterygium surgery, a conjunctival adv ancement flap with sutures was done in 47 cases, while graft on autolog ous serum done on 60 cases, in 7cases bare sclera kept. Results: Good stability of conjunctival flap and minimal inflammation was seen in advancement flap with sutures. While no inflammation, good acceptance but few cases of graft instability was seen in graft on autologous serum, and the recurrence was comparable in both the studies. Conclusion: Efficacy, safety and cost effectiveness is good with both the procedures but the stability is better with advancement flap with sutures and better acceptance of graft with least inflammation in graft on autologous serum group. However recurrence rate is comparable in both the procedures. Keywords: Conjunctival advancement flap, Autologous graft, Pterygium.
