To evaluate the efficacy of combined 25-gauge microincision vitrectomy surgery (MIVS) and toric intraocular lens (IOL) implantation with posterior capsulotomy.
Noncomparative, interventional case series performed at a single center. Twelve patients with vitreoretinal disease and cataracts, with preexisting regular corneal astigmatism greater than 1 diopter, underwent 25-gauge MIVS and toric IOL implantation with posterior capsulotomy.
The toric IOL was successfully implanted in each case. At 6 months postoperatively, mean axis rotation was 5.7° ± 3.1°. At 1 month postoperatively, mean uncorrected and best corrected visual acuity improved; the improvement was maintained after 6 months. The absolute residual refractive cylinder was significantly lower postoperatively than the pre-existing regular corneal cylinder (P = .003). There were no surgical complications except temporary posterior iris synechiae in one case.
Combined 25-gauge MIVS and toric IOL implantation with posterior capsulotomy is a practical and safe method to treat vitreoretinal disease and cataracts with pre-existing corneal astigmatism.
评估25G微创玻璃体切割手术(MIVS)联合散光人工晶状体(IOL)植入及后囊切开术的疗效。
在单一中心进行的非对照性干预病例系列研究。12例患有玻璃体视网膜疾病和白内障且术前存在规则角膜散光大于1屈光度的患者接受了25G MIVS联合散光IOL植入及后囊切开术。
每例均成功植入散光IOL。术后6个月,平均轴旋转度为5.7°±3.1°。术后1个月,平均未矫正视力和最佳矫正视力均有改善;6个月后仍维持改善状态。术后绝对残余屈光柱镜显著低于术前存在的规则角膜柱镜(P = 0.003)。除1例出现暂时性虹膜后粘连外,无手术并发症发生。
25G MIVS联合散光IOL植入及后囊切开术是治疗伴有术前角膜散光的玻璃体视网膜疾病和白内障的一种实用且安全的方法。
