Our purpose was to examine the long-term efficacy of toric intraocular lens (IOL) implantation in cataract patients with high astigmatism due to corneal ectasia, who underwent phacoemulsification cataract surgery. Five eyes of 3 cataract patients with topographically stable keratoconus or pellucid macular degeneration (PMD), in which phacoemulsification with toric IOL implantation was used to correct high astigmatism, are reported. Objective and subjective refraction, visual acuity measurement and corneal topography were performed in all cases before and after cataract surgery. In all cases, there was a significant improvement in visual acuity, as well as refraction, which remained stable over time. Specifically, in subjective refraction, all patients achieved visual acuity from 7/10 to 9/10 with up to -2.50 cyl. Corneal topography also remained stable. Postoperative follow-up was 18-28 months. Cataract surgery with toric IOL implantation seems to be safe and effective in correcting astigmatism and improving visual function in cataract patients with topographically stable keratoconus or PMD.
我们的目的是研究在接受白内障超声乳化手术的、因角膜扩张导致高度散光的白内障患者中植入散光人工晶状体（IOL）的长期疗效。本文报告了3例患有地形稳定圆锥角膜或透明晶状体黄斑变性（PMD）的白内障患者的5只眼，这些患者采用超声乳化联合散光IOL植入术来矫正高度散光。在白内障手术前后，对所有病例进行了客观和主观验光、视力测量及角膜地形图检查。所有病例的视力以及验光结果均有显著改善，且随时间保持稳定。具体而言，在主观验光中，所有患者的视力达到了7/10至9/10，散光最高达-2.50柱镜。角膜地形图也保持稳定。术后随访时间为18至28个月。对于患有地形稳定圆锥角膜或PMD的白内障患者，超声乳化联合散光IOL植入术在矫正散光和改善视觉功能方面似乎是安全有效的。
