摘　　要：目的根据白内障术前角膜散光状态，选择不同位置小切口，评价矫正术前散光及术后视力结果。方法对2013年9月至2015年10月在原州区人民医院眼科就诊的59例（68只眼）术前角膜散光≥2．0D的年龄相关性白内障患者，实施小切口白内障囊外摘除术。按照切口位置的不同分为实验组28例（33只眼），切口位于角膜散光最大的径线上；对照组31例（35只眼），切口位于正上方。分别观察两组患者术后3d、1个月和3个月角膜散光、裸眼视力变化情况。结果术前两组患者平均角膜散光和平均裸眼视力无显着性差异。术后两组平均角膜散光均较术前减少，实验组术后各时间段平均角膜散光度明显低于对照组，差异均有统计学意义（P〈0．05）。两组术后平均裸眼视力均较术前提高，实验组各时间段平均裸眼视力高于对照组，差异均有统计学意义（P〈0．05）。结论对于角膜散光≥2．0D的年龄相关性白内障患者，选择合适位置小切口，能够有效地矫正术前角膜散光和提高术后裸眼视力。Objective To select different position of small incision for cataract based on preoper- ative corneal astigmatism and to evaluate the preoperative astigmatism correction and postoperative vi- sion outcomes. Methods Data from 59 cases （68 eyes） age-related cataract patients were collected of preoperative corneal astigmatism （≥2.0 diopter, D）, the small incision cataract surgery （SICS） were implemented. According to the position of incision the patients were divided into experimental group and control group. Experimental group included 28 cases （33 eyes）, the incision on the corne- al astigmatism biggest meridian; Control group included 31 cases （35 eyes）, the incision was located in the upper part. Corneal astigmatism and uncorrected visual acuity （UCVA） changes from two groups was detected in 3 days, 1 month and 3 months after operation, respectively. Results There was no significant difference （P 〉0.05） on preoperative average corneal astigmatism and UCVA on two groups. Postoperative average corneal astigmatism compared with preoperative reduction was on both groups, however, the average corneal astigmatism in the experimental group after surgery at each time period was significantly lower vs the control group, differences were statistically signifi- cant （P 〈0.05）. The mean postoperative UCVA of all patients with good results compared with preop-erative on both groups. The mean UCVA in the experimental group after surgery at each time peri- od was higher than the control group, the difference had statistical significance （P 〈0.05）. Conclu- sions For corneal astigmatism≥2.0 D age-related cataract patients, select small incision at different position can effectively correct preoperative corneal astigmatism and improve the postoperative UCVA.
