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.
Vissum-Instituto Oftalmológico de Alicante, Alicante, Spain.
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.
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<.05). Astigmatism analysis by vectors showed a mean surgically induced astigmatism vector of 0.99 x 1 degrees and a mean difference vector of 0.23 x 8 degrees. The mean index of success was 0.11 +/- 0.15. Ninety-one percent of astigmatism was corrected. The mean IOL axis rotation was -1.75 +/- 2.93 degrees; the rotation was 10 degrees or less in all eyes. No complications occurred.
Implantation of a toric IOL after MICS was a safe, precise, and effective procedure to correct moderate to high astigmatism in cataract patients.

评估微切口白内障手术（MICS）联合矫正中高度散光的散光型人工晶状体（IOL）植入术治疗白内障合并中高度散光患者的疗效。
西班牙阿利坎特 Vissum-Instituto Oftalmológico。
本前瞻性非随机研究纳入了有明显视力障碍且合并中高度散光（>2.00 屈光度[D]）的白内障患者。行 MICS 后，在囊袋内植入 Acri.Comfort 646 TLC 散光型 IOL。术后 3 个月测量裸眼（UDVA）和最佳矫正（CDVA）远视力、残余屈光度球镜、残余屈光度和角膜散光柱镜及 IOL 轴位。用 Alpins 法对散光进行向量分析。
该研究纳入 21 只眼（12 例患者）。16 只眼（76.1%）的 UDVA 达到 20/40 或更好，18 只眼（85.7%）的 CDVA 达到 20/30 或更好。术后平均散光柱镜显著降低，从-4.46 D +/- 2.23（SD）降至-0.45 +/- 0.63 D（P<.05）。散光向量分析显示，平均手术诱导散光向量为 0.99 x 1 度，平均差异向量为 0.23 x 8 度。平均成功率指数为 0.11 +/- 0.15。91%的散光得到矫正。平均 IOL 轴位旋转为-1.75 +/- 2.93 度；所有眼的旋转均小于 10 度。无并发症发生。
MICS 后植入散光型 IOL 是治疗白内障合并中高度散光患者的一种安全、精确、有效的方法。
