摘　　要：目的探讨微切口白内障超声乳化术的临床疗效。方法将90例白内障患者随机分为试验组44例（50只眼）和对照组46例（50只眼）。试验组使用微切口白内障超声乳化术，对照组使用常规超声乳化术，观察两组术后视力、平均角膜内皮细胞密度、平均角膜散光度、平均手术源性散光度。结果术后第1天、第7天及第30天的视力／〉0．5比例分别是：试验组60％、72％、88％；对照组46％、62％、84％；术后第7天、第30天试验组平均角膜内皮细胞密度明显高于对照组，差异有显著性（P均〈0．01）；平均角膜散光度和平均手术源性散光度术后第7天和第30天对照组均大于试验组，差异有统计学意义（P〈0．01）。结论双手微切口白内障超声乳化吸除术是一种新型的手术方法，具有安全、有效、微创地临床特点。Objective To compare the clinical effect of the two different methods （micro-incision phacoemulsification or regular phacomulsificaion） to treat the cataract patients.Methods Ninety cataract pa- tients were randomly divided into two groups： test group including 44 cases of 50 eyes, control group including 46 cases of 50 eyes.The test group was treated by micro-incision phacoemulsification, and the other was treated by regular phacomulsification.The vision and corneal endothelial cell density in both groups were observed pre- operatively, on the day 1, 7, and 30 postoperatively.Knife Keratometry measurements were obtained preoperatively, at day 7 and 30 postoperative by Nikon Keratometry.The mean surgically induced astigmatism （SIA） and mean postoperative uncorrected visual acuity between the two groups were compared up to 6 months post- operatively, SIAs were analyzed by ＂Holladay vector method＂.Results A visual acuity of 0.5 or better in test group was obtained in 60 %, 72 % and 88 % of the patients at day 1, 7 and 30 postoperatively.A visual acuity of 0.5 or better in control group was obtained in 46%, 62% and 84% of the patients at day 1, 7 and 30 post- operatively.There was a statistically significant difference between the two groups in mean endothelium cell count, surgically induced astigmatism and mean corneal astigmatism one week, one month after surgery.Conclusions Micro-incision phaeoemulfication is feasible, safe and effective surgery method for the cataract patient.
