Abstract

PURPOSE

This study aimed to evaluate the safety and efficacy of retropupillary fixation of an iris-claw intraocular lens (IOL; Verisyse polymethyl methacrylate IOL, Abbott Medical Optics [AMO], Netherlands) for the surgical correction of aphakia in microspherophakic eyes without sufficient capsular support.

DESIGN

This was a prospective, interventional, noncomparative case series.

METHODS

This interventional case series comprised 17 eyes of 9 microspherophakic patients. Retropupillary fixation of the Verisyse iris-claw IOL (AMO) was performed in all cases. The surgical time was measured. Corrected distance visual acuity, astigmatism, intraocular pressure (IOP), tissue reaction, pigment dispersion, and stability of the IOL were studied 1 day, 3 days, 1 week, 2 weeks, 1 month, and 6 months postoperatively.

RESULTS

Eight patients had familial microspherophakia and one patient had Marfan's syndrome. Eighty-two percent of the cases achieved a visual acuity of 0.3 or better. There was no significant postoperative inflammatory reaction. Transient elevation of IOP was recorded in two cases in the 1st week only. One IOL developed disengagement of one of the haptics from the iris and was successfully re-engaged. All the other IOLs were well centered and stable. The mean surgical time was 18.0 ± 4.5 min.

CONCLUSIONS

Retropupillary fixation of an iris-claw IOL is a safe and effective procedure that provides early visual recovery. It is also a time-saving method for correcting aphakia in microspherophakic eyes without sufficient capsular support.

摘要

目的

本研究旨在评估虹膜爪型人工晶状体（IOL；Verisyse聚甲基丙烯酸甲酯IOL，雅培医疗光学公司[AMO]，荷兰）瞳孔后固定术用于无足够囊袋支撑的小眼球无晶状体眼手术矫正的安全性和有效性。

设计

这是一项前瞻性、干预性、非对比性病例系列研究。

方法

该干预性病例系列包括9例小眼球患者的17只眼。所有病例均行Verisyse虹膜爪型IOL（AMO）瞳孔后固定术。测量手术时间。在术后1天、3天、1周、2周、1个月和6个月研究矫正远视力、散光、眼压（IOP）、组织反应、色素播散和IOL的稳定性。

结果

8例患者有家族性小眼球，1例患者有马凡综合征。82%的病例术后视力达到0.3或更好。术后无明显炎症反应。仅在第1周有2例记录到眼压短暂升高。1个IOL的1个袢从虹膜脱离，后成功重新固定。所有其他IOL居中良好且稳定。平均手术时间为18.0±4.5分钟。

结论

虹膜爪型IOL瞳孔后固定术是一种安全有效的手术方法，可实现早期视力恢复。对于无足够囊袋支撑的小眼球无晶状体眼，它也是一种节省时间的无晶状体矫正方法。
