【摘要】 目的 观察在表面麻醉下不作结膜瓣和传统的以穹窿为基底结膜切开的小切口白内障摘除联合5.5 mm直径人工晶状体植入术的临床效果。 方法 收集2007年1月－2010年12月资料较完整的老年性白内障160例，将160例320只眼随机分成两组，每组各80例160只眼。在表面麻醉下行小切口白内障手术。A组不做结膜瓣，行长5.5 mm角巩膜缘的平行切口； B组行以穹窿为基底的传统的结膜瓣，做长5.5 mm角巩膜平行切口；两组均行手法小切口白内障劈核摘除联合5.5 mm直径硬质人工晶状体植入。观察术后效果及术后并发症。 结果 术后1个月，患者眼部舒适者:A组154只眼（96.25%），B组141只眼（88.13%），两组差异有统计学意义（χ2=7.332，Plt;0.05）。术后结膜退缩、下垂、巨大瘢痕：A组7只眼（4.38%），B组29只眼（18.13%），两组差异有统计学意义（χ2=15.149，Plt;0.01），两组患者术后1 d、1周及1个月视力比较：1 d，A组120只眼（75.00%），B组128只眼（80.00%）（χ2=1.467，Pgt;0.05）；1周，A组130只眼（81.25%），B组132只眼（82.25%）（χ2=0.084，Pgt;0.05）；1个月，A组138只眼（86.25%），B组139只眼（86.86%）（χ2=0.027，Pgt;0.05）；角膜水肿于术后2周后均消退。 结论 在表面麻醉下不做结膜瓣较做结膜瓣小切口白内障劈核摘除术联合人工晶状体植入术省时、对眼表面破坏小，角巩膜切口较小且较为隐闭，术后恢复快。在基层医院是一种较好的白内障手术方法。【Abstract】 Objective To observe the clinical effect of non-conjunctival flaps and traditional conjunctival flaps choper extracapsular cataract extraction (ECCE) on patients with senile cataracts. Methods The clinical data of 160 patients with cataracts between January 2007 and December 2010 were collected. The patients were randomly divided into two groups with 80 patients (160 eyes) in each group. The patients in group A underwent the small-incision choper ECCE surgery with non-conjunctival flaps; while the patients in group B underwent the traditional conjunctival flaps. Then the total effective rate, incidence of complications, and satisfaction rate of the two groups were analyzed and compared. Results One month after the surgery, the comfort was found in 154 eyes (96.25%) in group A and in 141 eyes (88.13%) in group B; the difference was significant (χ2=7.332，Plt;0.05). The complications after the surgery including conjunctiva retraction, nutation, and huge scar were found in 7 eyes (4.38%) in group A and in 29 eyes (18.13%) in group B, and the difference was significant (χ2=15.149，Plt;0.01) . The visual acuity of the patients one day, one week and one month after the surgery in the two groups were: one day: 120 eyes (75.00%) in group A and 128 eyes (80.00%) in group B (χ2=1.467，Pgt;0.05); one week: 130 eyes (81.25%) in group A and 132 eyes (82.25%) in group B (χ2=0.084，Pgt;0.05); one month: 138 eyes (86.25%) in group A and 139 eyes (86.86%) in group B (χ2=0.027，Pgt;0.05). The cornea edema was alleviated half month after the surgery. Conclusion Compared with the traditional way, non-conjunctival flaps ECCE may save the surgical time, reduce the damage of the ocular surface, improve the visual acuity and received higher satisfaction rate and less conjunctive complication, which is a good surgical method in local hospital.
