Different surgicaI methods on the tear fiIm stabiIity in treating pterygium patients / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

· AlMTo compare the therapeutic effects of different surgical methods in treating pterygium patients and to observe tear film stability. · METHODS: A total of 120 pterygium patients ( 120 eyes) were divided into three groups, each 40 cases (40 eyes).Data including SchirmerⅠtest (SⅠt), tear break-up time ( BUT) , corneal fluorescein staining ( CFS) were recorded preoperatively and postoperatively to evaluate the clinical efficacy of surgery and the effects of tear function changes. ·RESULTS:There were no significant differences in BUT in group A before the operation and one month after operation.Groups B and C showed significant difference before and after operation, but differences were not statistically significant ( all P compared it between groups B and C, there showed no significant difference; Group A showed no significant difference in SⅠt compared with preoperative, SⅠt of groups B and C were significant differences compared with preoperative (P ·CONCLUSlON Pterygium excision combined with self-corneal limbal stem cell transplantation and Tenon capsule closed is an ideal surgical to reduce the recurrence and improve tear film function to some extent.
