Abstract:Objective: To explore the effects of amniotic membrane transplantation and conjunctival autograft transplantation on visual quality, corneal refractive power and tear film function of patients undergoing pterygium surgery. Methods: A prospective study was conducted among 220 patients undergoing pterygium surgery at the hospital between June 2018 and November 2019. They were randomly divided into control group and experimental group by random number table method, 110 cases in each group. The control group was treated with amniotic membrane transplantation after pterygium surgery, and the experimental group was treated with conjunctival autograft transplantation. Therapeutic effects of the 2 groups were compared. Visual quality, corneal refractive power and tear film function of the 2 groups were observed before and after treatment. Meanwhile, the incidence of complications was compared between the 2 groups. Results: There were no significant differences in the total response rate and recurrence rate between the 2 groups (P>0.05). Compared with the same group before treatment, MTF, SR, SIT and BUT of both groups were significantly increased. Besides, the above indexes of experimental group were significantly higher than those of the control group (P<0.05). However, TF-OSI and corneal refractive power were significantly reduced, which were significantly lower in the experimental group than the control group (P<0.05). The recurrence rate and the incidence of complications in experimental group were slightly lower than those in the control group (P>0.05). Conclusion: Clinical effects of conjunctival autograft transplantation and amniotic membrane transplantation are similar in patients undergoing pterygium surgery. However, the former is more conducive to the improvement of visual quality, corneal refractive power and tear film function. Besides, the risk of complications is lower.
