Abstract：Objective:To investigate the effect of different bulbar conjunctiva transplantation and postoperative intervention on the comfort and efficacy of patients with pterygium.Methods:A total of 200 patients(200 eyes)with pterygium who were admitted to the hospital from January 2017 to December 2019 were selected as the research objects,and they were divided into 4 groups according to the random number table method,with 50 cases(50 eyes)in each group.Groups A and B were treated with excision combined with autologous free conjunctival flap transplantation,group C and D were treated with excision combined with limbal stem cell transplantation,and group B and D wore corneal bandage lenses after surgery.The postoperative eye discomfort,visual acuity,corneal epithelial healing time,cure rate and recurrence rate of the four groups were observed and compared.Results:The 4 groups of patients had different degrees of eye discomfort after operation,which was relieved after 3 days and basically disappeared after 2 weeks.1,3 and 7 days after operation,the eye discomfort of group B was lighter than that of group A,and the eye discomfort of group D was lighter than that of group C,and there was no statistically significant difference between group A and group C,and group B and group D(P＞0.05).On the 1 and 3 days after operation,the uncorrected visual acuity of 4 groups decreased to varying degrees,the visual acuity improved 2 weeks after the operation,and the visual acuity was stable 12 weeks after operation(P＜0.05).1 and 3 day after operation,the visual acuity of group B was higher than that of group A,and the visual acuity of group D was higher than that of group C(P＜0.05),but there was no significant difference between group A and group C,group B and group D(P＞0.05).The corneal epithelial healing time of the four groups of patients was about 4～6 days.The corneal epithelial healing time of group B was shorter than that of group A,and that of group D was shorter than that of group C(P＜0.05).The differences between group A and group C,group B and group D were all not statistically significant(P＞0.05).Conclusion:Resection combined with limbal stem cell transplantation is effective in the treatment of patients with pterygium,and the recurrence rate is low.Wearing a corneal bandage lens can reduce postoperative eye discomfort,facilitate corneal epithelial healing and early visual acuity stability,and has positive significance for the treatment of pterygium.
