目的:探讨透明角膜切口白内障超声乳化吸除联合折叠人工晶状体植入术后角膜散光的变化情况。方法:收集年龄相关性白内障患者58例79眼,全部实施透明角膜小切口超声乳化吸除联合折叠人工晶状体植入术。观察术前,术后3d;1wk;1mo视力及角膜散光情况。结果:术后1mo视力提高明显且趋于稳定。平均角膜散光度,术后1mo较1wk明显减少,二者比较差异有显著性。结论:3.2mm透明角膜切口白内障超声乳化吸除联合折叠人工晶状体植入术,术后角膜散光小,视力恢复快,稳定时间短,是理想的白内障手术切口方法。

AIM:To explore the change of corneal astigmatism after phacoemulsification associated with fold artiphakia lens embedded with hyaline corneal incision.METHODS:Seventy-nine eyes of 58 cases were enrolled. All cases underwent similar phacoemulsifica-tion combined with fold artiphakia lens implantation.The changes of corneal astigmatism before and 3 days,1 week,1 month after operation were compared as well as visual acuity.RESULTS:One month after operation,visual acuity elevated and became stabilization. Average corneal astigmatism were decreased obviously 1 month compared with 1 week after operation. There was significant difference.CONCLUSION:Phacoemulsification combined with fold artiphakia lens implantation with 3.2mm hyaline corneal incision may be a safe and effective method to treat cataract for smaller corneal astigmatism,quicker visual recovery and shortter stable time.
