In eyes with compromised capsule support, sutureless scleral fixation is a popular method of placing a posterior chamber intraocular lens (PCIOL). We describe an endoscope-assisted sutureless technique for intrascleral fixation of a 3-piece PCIOL.
Eyes of patients who had endoscope-assisted scleral-fixated intraocular lens (SFIOL) implantation were examined retrospectively. The technique comprised direct capture of the IOL haptic with a forceps through a pars plana sclerotomy with subsequent haptic fixation into scleral tunnels created with a 26-gauge needle. The endoscope was used to visualize haptic positioning under the iris and ensure proper centration of the IOL.
Thirteen eyes of 13 patients were examined. The mean age of the patients was 68.2 years (range, 38-87 years), and the mean follow-up was 13.6 months (range, 5-23 months). The indications for surgery were a subluxated IOL (6 eyes), postoperative aphakia (5 eyes), and a subluxated cataract (2 eyes). The mean best-corrected visual acuity ± SD improved significantly from 1.2 ± 0.6 logMAR preoperatively to 0.6 ± 0.7 logMAR at last the follow-up (paired Welch test; t = 2.69; = .023). IOL stability and centration were maintained in all patients.
Endoscopic visualization during sutureless SFIOL implantation helped improve haptic localization, minimize intraoperative complications, and achieve excellent IOL centration.
在囊袋支撑功能受损的眼中,无缝线巩膜固定术是植入后房型人工晶状体(PCIOL)的常用方法。我们描述一种用于三片式PCIOL巩膜内固定的内镜辅助无缝线技术。
回顾性检查接受内镜辅助巩膜固定人工晶状体(SFIOL)植入术患者的眼部情况。该技术包括通过睫状体扁平部巩膜切口用镊子直接抓取人工晶状体襻,随后将襻固定到用26号针制作的巩膜隧道中。使用内镜观察襻在虹膜下方的位置,并确保人工晶状体正确居中。
检查了13例患者的13只眼。患者的平均年龄为68.2岁(范围38 - 87岁),平均随访时间为13.6个月(范围5 - 23个月)。手术适应证为人工晶状体半脱位(6只眼)、术后无晶状体眼(5只眼)和晶状体半脱位合并白内障(2只眼)。最佳矫正视力±标准差从术前的1.2±0.6 logMAR显著提高到末次随访时的0.6±0.7 logMAR(配对韦尔奇检验;t = 2.69;P = 0.023)。所有患者的人工晶状体均保持稳定且居中。
无缝线SFIOL植入术中的内镜可视化有助于改善襻的定位,减少术中并发症,并实现人工晶状体的良好居中。
