To describe a new surgical technique for sutureless intrascleral intraocular lens (IOL) fixation with an adapted retinal scraper used as an instrument "the Catcher Pole" to retrieve the IOL haptic through a scleral tunnel.
Public Eye Hospital, Roma, Italy.
Retrospective case series.
Twenty-one eyes from 19 patients who underwent sutureless intrascleral IOL fixation were studied. A standard three-piece posterior chamber IOL (PCIOL) was implanted in aphakia or rescued and fixated in cases of dislocated PCIOL. A 23 to 25 G retinal loop scraper (the "Catcher Pole") was inserted through a 1.5 mm long tunneled sclerotomy performed on the horizontal meridian, to capture, hold and externalize the tip of the haptic of the IOL. A flange created with an handheld cautery on the externalized haptic tip prevents IOL slippage. The best-corrected visual acuity (BCVA), central corneal pachymetry (CCP), IOL tilt and complications were assessed.
In twenty-one eyes of 19 patients, the mean preoperative BCVA was 0.61 logMAR units ±0.05 SD, and the mean postoperative BCVA improved significantly to 0.18 logMAR units at three months ±0.05 SD (=0.002). The mean preoperative CCP was 610 µ ±17 SD and the mean postoperative CCP 623 µ ±16 SD, (=0.73). In the subgroup that underwent IOL tilt evaluation, mean IOL tilt was 3.19±2.01. The postoperative complications included iris capture of the IOL in one eye (4,7%) and transient ocular hypertension in two eyes (9,4%).
The "Catcher Pole" sutureless intrascleral IOL fixation technique is easy to perform with reduced anterior chamber manipulations and achieves both anatomical and optical stability.
描述一种新的无缝线巩膜内人工晶状体(IOL)固定手术技术,该技术使用一种经过改良的视网膜刮匙作为“捕捉杆”器械,通过巩膜隧道取出IOL襻。
意大利罗马公立眼科医院。
回顾性病例系列。
研究了19例接受无缝线巩膜内IOL固定术的患者的21只眼。将标准三件式后房型IOL(PCIOL)植入无晶状体眼中,或在脱位的PCIOL病例中进行挽救和固定。通过在水平子午线上进行的1.5毫米长的隧道式巩膜切开术插入一个23至25G的视网膜环形刮匙(“捕捉杆”),以捕获、固定并将IOL襻的尖端引出眼外。用手持烧灼器在引出眼外的襻尖端上制作一个凸缘,可防止IOL滑动。评估最佳矫正视力(BCVA)、中央角膜厚度(CCP)、IOL倾斜度和并发症。
在19例患者的21只眼中,术前平均BCVA为0.61 logMAR单位±0.05标准差,术后3个月时平均BCVA显著提高至0.18 logMAR单位±0.05标准差(P = 0.002)。术前平均CCP为610µ±17标准差,术后平均CCP为623µ±16标准差(P = 0.73)。在接受IOL倾斜度评估的亚组中,平均IOL倾斜度为3.19±2.01。术后并发症包括1只眼的IOL捕获虹膜(4.7%)和2只眼的短暂性高眼压(9.4%)。
“捕捉杆”无缝线巩膜内IOL固定技术操作简便,前房操作减少,可实现解剖和光学稳定性。
