Abstract：Objective: To study the efficacy of pterygium excision combined with superior temporal limbal stem cell transplantation in the treatment of pterygium. Methods: A total of 60 pterygium patients admitted to hospital from January 2019 to January 2020 were divided into two groups according to the random number table method, one group was the control group, According to the simple random grouping method, they were randomly divided into two groups (study group and control group with 30 cases each). The control group was treated with pterygium excision alone, while the study group was treated with pterygium excision combined with superior temporal limbal stem cell transplantation. Before and after operation, corneal astigmata, naked eye vision, postoperative corneal wound healing time, total effective rate, complication rate and recurrence rate were compared between the two groups. Results: there was no difference in preoperative corneal astigmatism and naked eye vision between the two groups (P>0.05). The postoperative corneal astigmatism of the two groups was lower than that of the preoperative, and the visual acuity of the naked eye was higher (P<0.05). Compared with the control group, the study group had lower postoperative keratodispersion and recurrence rates, higher naked eye vision and total effective rate, and shorter corneal wound healing time (P<0.05). There was no difference in postoperative complication rate between the two groups (P>0.05). Conclusion: Pterygium excision combined with superior temporal limbal corneal dry cell transplantation is effective in the treatment of pterygium patients, which can effectively reduce the patients' corneal astigmata, improve the level of naked eye vision, and promote the rapid healing of corneal wound, with low complication rate and recurrence rate.
