To report the long-term visual outcomes and complications after implantation of scleral-fixated posterior chamber intraocular lenses (PC IOLs).

Case series.
This study reviewed the records of patients who had anterior vitrectomy and scleral-fixated PC IOL implantation between 1993 and 2008 and had a minimum follow-up of 6 months.
The study comprised 82 eyes of 72 patients (47 men). The mean follow-up was 83.3 months (range 6.7 to 166.5 months) and the mean age at surgery, 62 years (range 15 to 97 years). The mean improvement in corrected distance visual acuity (CDVA) was 1.6 Snellen chart lines of vision, which was statistically significant; 59 eyes (72%) had an improved or unchanged CDVA, and 23 eyes (28%) had a reduced CDVA. The most common postoperative complication was ocular hypertension (25 eyes [30.5%]). Suture breakage occurred in 5 eyes (6%) after a mean of 4.9 years; 4 of these patients were younger than 40 years. Overall, 44 eyes (53.7%) had at least 1 complication, 36.4% within 1 week postoperatively and 63.6% after 1 week. Thirteen eyes (15.8%) required at least 1 further operation.
Scleral-fixated PC IOL insertion provided favorable visual outcomes in many cases. Complications were common, and suture rupture is an important long-term complication, particularly in young patients. These issues affect IOL choice for the surgical treatment of aphakia and should be discussed with patients during the consent process.

报告巩膜固定后房型人工晶状体（PC IOL）植入术后的长期视力结果和并发症。

病例系列。
本研究回顾了 1993 年至 2008 年间接受前玻璃体切割术和巩膜固定 PC IOL 植入术且随访时间至少 6 个月的患者的病历。
研究共纳入 72 例患者的 82 只眼（47 名男性）。平均随访时间为 83.3 个月（6.7 至 166.5 个月），手术时平均年龄为 62 岁（15 至 97 岁）。平均矫正远视力（CDVA）提高了 1.6 个 Snellen 图表行，具有统计学意义；59 只眼（72%）的 CDVA 改善或保持不变，23 只眼（28%）的 CDVA 下降。最常见的术后并发症是高眼压（25 只眼[30.5%]）。5 只眼（6%）在平均 4.9 年后发生缝线断裂，其中 4 例患者年龄小于 40 岁。总的来说，44 只眼（53.7%）至少发生 1 种并发症，36.4%在术后 1 周内，63.6%在术后 1 周后。13 只眼（15.8%）至少需要再次手术。
巩膜固定后房型人工晶状体植入术为许多患者提供了良好的视力结果。并发症很常见，缝线断裂是一个重要的长期并发症，尤其是在年轻患者中。这些问题影响了手术治疗无晶状体眼的人工晶状体选择，应在征得患者同意的过程中与患者进行讨论。
