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 2nd postoperative week and then returned to baseline values thereafter. Mean SIA gradually decreased to reach 0.12 D by the 6th 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 3rd postoperative month but it continued till the 6th month postoperatively.展开更多
