The different topographic parameters and SIA were analyzed pre- and postoperatively. ● RESULTS: There was no significant changes in corneal topographic parameters at different follow up periods. Only surface regularity index changed significantly in the 2^(nd) postoperative week and then returned to baseline values thereafter. Mean SIA gradually decreased to reach 0.12 D by the 6^(th) postoperative month. ● CONCLUSION: Corneal surface and astigmatic changes are insignificant in either early or late postoperative periods following combined phacoemulsification and 25-G TSV. The SIA was the minimum among previous reports on sutureless vitrectomy alone or combined with phacoemulsification. Improvement of SIA did not stop at the 3^(rd) postoperative month but it continued till the 6^(th) month postoperatively. 关 键 词：角膜的地志的索引 通过手术导致的散光 25 计量器无缝术的 vitrectomy PHACOEMULSIFICATION
