RESUMEN
Objective To compare the treatment effect of amniotie membrane transplantation(AMT) combine mitomycin C(MMC) and corneal limbal stem cell autograft transplantation combine mitomycin C surgery.Methods 234 pterygium patients(239eye) were randomly divided into two groups: routine resection and AMT combine mitomycin C,limbal epithelial autograft transplantation combine mitomycin C. Results The recrudescnce (3.25 % ) of AMT combine mitomycin C is lower than routine resection and limbal epithelial autograft transplantation combine mitomycin C(4.31% ). But there was no significant difference between these two groups. Conclusion The treatment of AMT combine mitomycin C is as good as Iimbal epithelial autograft transplantation combine mitomyein C and the recrudescnce is lower.
