Suture Selection for Incision Closure in Pediatric Cataract Surgery: A Dilemma for Pediatric Ophthalmologists

Abstract

Purpose: To measure and compare suture-related complications in children undergoing cataract surgery with a surgical incision closure performed by either a 10-0 nylon suture followed by suture removal within 1 to 2 weeks after surgery or a 10-0 polyglactin suture left in situ. Methods: This was a prospective, non-randomized cohort study. All children with bilateral cataracts who underwent cataract surgery with a surgical incision closure by non-absorbable 10-0 nylon sutures followed by suture removal within 1 to 2 weeks after surgery in their first eye and incision closure by absorbable 10-0 polyglactin sutures left in situ after their second eye surgery. The frequency of suture-related complications (vascularization near to suture, loosening of suture, mucus accumulation, early rupture, and infective keratitis) was noted for 10-0 nylon and 10-0 polyglactin sutures. Results: Eighty-two eyes of 41 children were enrolled in the study. All children were observed until 3 months after surgery. Of the 10-0 nylon sutures, 2 (4.9%) were loose and 2 (4.9%) had underlying corneal edema. The remaining sutures (n = 37, 90.2%) were removed within 1 to 2 weeks after surgery. Of the 10-0 polyglactin sutures, 5 (12.2%) were loose, 2 (4.9%) were vascularized, and 3 (7.3%) had mucus infiltration. These sutures (n = 10, 24.3%) were removed 2 to 5 weeks after the second eye surgery. The remaining polyglactin sutures (n = 31, 75.6%) were left in situ. Conclusions: A higher frequency of suture-related complications was observed with the 10-0 polyglactin sutures than the 10-0 nylon sutures. The authors recommend using 10-0 nylon sutures with suture removal within 1 to 2 weeks after surgery over using 10-0 polyglactin sutures for incision closure in pediatric cataract surgeries.
