Abstract

AIMS: To review the effect of surgery type on the postoperative recovery & astigmatism in pterygium surgery. SETTINGS AND DESIGN: Randomized comparative clinical trial. MATERIALS AND METHODS: Forty six patients (46 eyes) with primary pterygium were randomised to undergo pterygium surgery using either autologous fibrin glue (23 eyes) or 10-0 nylon sutures (23 eyes) to attach the conjunctival autograft. The patients were followed up 1day, 1wk, 2wks & 6 weeks. Outcome measures were keratometry changes & postoperative recovery.. The preoperative and postoperative keratometric measurements, evaluated using keratometer, were noted. RESULTS: Corneal astigmatism was significantly reduced in the total group from 2.94(SD- 0.52) diopter to 1.91 (sd 0.57) diopter (p 0.05). The intensity of the postoperative watering, itching, were significantly lower in the autologous fibrin glue group than in the suture group (p<0.001). Postoperative redness was absent in 47.82% (11cases) and mild in 52.18% (13 cases) 2 weeks postoperatively in the autologous fibrin group while in sutured group 17.4% (4cases) had mild redness and 82.6% (19 cases) had moderate redness 2weeks postoperatively. CONCLUSION: Corneal astigmatism is reduced by
