Comparison of clinical efficacy between suture embedding method and bandage contact lens in pterygium excision

Objective To compare the clinical efficacy between suture embedding method in pterygium excision and bandage contact lens after pterygium excision. Methods A prospective, randomized and controlled case study. The data of 106 eyes of 106 patients who underwent pterygium excision combined with autologous conjunctival flap graft transplantation in this hospital from Aug. 2017 to Aug. 2018 were collected and analyzed. All patients were divided into three groups randomly, included suture embedding group, bandage contact lens group and control group. Results The pain was assessed with visual analogue scale (VAS). The scores in bandage contact lens group was less than that in suture embedding group at 1day postoperatively(P=0.001). There was no significant difference of pain score between bandage contact lens group and suture embedding group at 3 and 7 days after operation(P=0.213, 0.676). The area of corneal epithelium fluorescent staining in bandage contact lens group were less than that in suture embedding group at 1 and 3 days after operation (P=0.001, 0.020). There was no significant difference between bandage contact lens group and suture embedding group at 7 days after operation in corneal epithelium fluorescent staining area (P=0.173). Conclusion Application of bandage contact lens after pterygium excision in alleviation of corneal irritation and pain is better than suture embedding method. And bandage contact lens can promote corneal epithelial healing effectively. Key words: Surgery, pterygium; Bandage contact lens, corneal; Suture embedding
