To evaluate the indications, visual outcomes, and complication rate after implantation of a posterior chamber iris-claw aphakic intraocular lens (IOL).
Department of Ophthalmology, University Medicine Charité Berlin, Berlin, Germany.
Retrospective case series.
Eyes without adequate capsule support had posterior chamber iris-claw aphakic IOL implantation (Verisyse/Artisan) between 2005 and 2010.
The study comprised 137 eyes (126 patients). The mean follow-up was 5 months (range 1 to 48 months). The IOLs were inserted during primary lens surgery in 10 eyes (7.3%), during an IOL exchange procedure for dislocated posterior chamber IOLs in 95 eyes (69.4%), and as a secondary procedure in 32 aphakic eyes (23.3%). The final mean corrected distance visual acuity (CDVA) (0.38 ± 0.31 [SD] logMAR) was significantly better than preoperatively (0.65 ± 0.58 logMAR) (P < .05). In 128 eyes (93.4%), postoperative refractive errors were within ±2.00 diopters (D) of emmetropia. Complications included slight temporary pupil ovalization in 34 eyes (24.8%), cystoid macular edema in 12 eyes (8.7%), hyphema in 3 eyes (2.1%), early postoperative hypotony in 7 eyes (5.1%) and elevated intraocular pressure in 6 eyes (4.3%), chronic uveitis in 1 eye (0.7%), toxic anterior segment syndrome in 1 eye (0.7%), and endophthalmitis in 1 eye (0.7%). Iris-claw IOL disenclavation occurred in 12 eyes (8.7%); all IOLs could be easily repositioned.
The retropupillary iris-claw IOL provided good visual outcomes with a favorable complication rate and can be used for a wide range of indications in eyes without adequate capsule support.

回顾性病例系列。
无足够囊袋支持的眼行后房型虹膜夹型人工晶状体（Verisyse/Artisan）植入术。
本研究共纳入 137 只眼（126 例患者）。平均随访时间为 5 个月（1 至 48 个月）。IOL 于 10 只眼（7.3%）的初次晶状体手术中植入，95 只眼（69.4%）的后房型 IOL 脱位置换术中植入，32 只眼（23.3%）作为二期手术植入。最终平均矫正远视力（CDVA）（0.38 ± 0.31 [SD] logMAR）明显优于术前（0.65 ± 0.58 logMAR）（P <.05）。128 只眼（93.4%）术后屈光不正度在±2.00 屈光度（D）以内。并发症包括 34 只眼（24.8%）轻微暂时瞳孔椭圆形，12 只眼（8.7%）黄斑囊样水肿，3 只眼（2.1%）前房积血，7 只眼（5.1%）早期术后低眼压和 6 只眼（4.3%）高眼压，1 只眼（0.7%）慢性葡萄膜炎，1 只眼（0.7%）毒性前节综合征和 1 只眼（0.7%）眼内炎。12 只眼（8.7%）发生虹膜夹 IOL 脱位，所有 IOL 均可轻松重新定位。
后房型虹膜夹型 IOL 提供了良好的视力结果，并发症发生率低，可用于无足够囊袋支持的广泛适应证。
