Application of continuous locking suture combined with corneal bandage contact lens in pterygium operation
Journal Title: Eye Science (Yanke Xuebao) - Year 2022, Vol 37, Issue 2
Abstract
[Objective:] To investigate the effect of continuous locking suture combined with corneal bandage lens in the operation of pterygium. [Methods:] A prospective randomized controlled clinical trial was conducted. From January 2018 to June 2021, 132 patients (180 eyes) who underwent pterygium excision combined with autologous limbal conjunctival flap transplantation were randomly divided into group A and group B according to the fixation of conjunctival fla. The patients in group A (64 cases, 90 eyes) were treated with intermittent suture and fixation, and the patients in group B (68 cases, 90 eyes) were treated with continuous locking suture. Both groups were given corneal bandage lenses at the end of the operation. The postoperative ocular pain score, postoperative effect and complications were compared between the two groups. [Results:] The pain score in group B was significantly lower than that in group A at 1 and 3 d after operation (P<0.01), and there was no significant difference in corneal staining score between the two groups at 1, 3 and 7 d after operation (P>0.05). There was no significant difference in breakup time of tear film (BUT) between the two groups before and 3 months after operation (P>0.05), but the BUT at 3 months after operation in the group was significantly better than that before operation (P<0.05). There was no significant difference in visual acuity between the two groups before and 2 weeks after operation (P>0.05). The visual acuity of the two groups was significantly improved 2 weeks after operation (P<0.05). During the follow-up of 3 months, the main postoperative complications of the two groups included delayed healing of superficial matrix injury after pterygium avulsion, conjunctival hyperplasia, conjunctival graft loosening and so on. [Conclusion:] Continuous locking suture combined with corneal bandage lens in the treatment of pterygium can promote the repair of corneal wound, reduce the postoperative irritation symptoms and improve the postoperative comfort of patients. It is necessary to increase the suture span during continuous locking suture, which can reduce the loosening of conjunctival graft after operation.
