目的：评价小切口白内障手术(MICS)联合环形人工晶状体(IOL)植入矫正白内障患者中高度散光的效果。MICS后，在囊袋内植入Acri.Comfort 646 TLC Toric IOL。术后3个月分别测量裸眼视力(UDVA)、矫正视力(CDVA)、残余屈光度及人工晶状体轴线。用Alpins法对散光进行向量分析。结果：12例21眼。UDVA>20/40者16眼(76.1%)，CDVA>20/30者18眼(85.7%)。术后平均屈光度由-4.46D+/-2.23(SD)降至-0.45+/-0.63D(P
PURPOSE: To evaluate the results of microincision cataract surgery (MICS) with toric intraocular lens (IOL) implantation to correct moderate to high astigmatism in patients with cataract.SETTING: Vissum-Instituto Oftalmologico de Alicante, Alicante, Spain.METHODS: This prospective nonrandomized study comprised patients with visually significant cataract and moderate to high astigmatism (>2.00 diopters [D]). After MICS, an Acri.Comfort 646 TLC toric IOL was implanted in the capsular bag. The uncorrected (UDVA) and corrected (CDVA) distance visual acuities, residual refractive sphere, residual refractive and keratometric cylinders, and IOL axis alignment were measured after 3 months. Vector analysis of astigmatism was by the Alpins method.RESULTS: The study included 21 eyes (12 patients). The UDVA was 20/40 or better in 16 eyes (76.1%), and the CDVA was 20/30 or better in 18 eyes (85.7%). The mean refractive cylinder decreased significantly after surgery, from -4.46 D +/- 2.23 (SD) to -0.45 +/- 0.63 D (P
