Effect of bandage lens after pterygium excision combined with corneal stem cell transplantation

Abstract

AIM: To evaluate the clinical effect of wearing bandage lens after pterygium excision combined with corneal stem cell transplantation. METHODS: This study was a prospective analysis. Totally 110 cases 110 eyes of pterygium excision combined with corneal stem cell transplantation admitted to our hospital from August 2015 to February 2018 were randomly divided into control group and observation group with 55 cases in each group. Patients in observation group wore bandage lens after operation. Visual analogue scale(VAS)was used to evaluated the pain 1, 3d and 1wk after operation. Fluorescein staining(FL)was used to evaluate the corneal epithelial healing and the incidence of complications. RESULTS: The VAS score and corneal epithelial healing score of the observation group were significantly lower than those of the control group at 1, 3d and 1wk after operation(PP>0.05). CONCLUSION: It is safe and effective to wear bandage lens after pterygium excision combined with corneal stem cell transplantation. It can relieve pain and promote epithelial healing after pterygium operation.
