To determine the functional and cosmetic outcomes of combined iris reconstruction lens (Ophtec) implantation and penetrating keratoplasty (PK) in eyes with acquired partial or complete aniridia.
Jules Stein Eye Institute and the Department of Ophthalmology, David Geffen School of Medicine at UCLA, Los Angeles, California, USA.
In a prospective nonrandomized single-center interventional case series, efficacy measures included improvement in cosmesis and reduction in glare, star bursts, and photophobia. Safety measures included changes in best corrected visual acuity (BCVA), reports of adverse events, and surgical complications.
The 9 eyes in the study had a history of penetrating or blunt trauma and were aphakic or in need of cataract surgery. Corneal pathologies necessitating transplantation included scarring, decompensation, or failure of a previous graft. Postoperatively, all patients were pleased with the cosmetic improvement of the study eye and all reported a reduction in visual disturbances. By the final follow-up examination, the BCVA improved in 4 patients but worsened in 5. Three adverse events were reported. There were no intraoperative surgical complications. The most serious postoperative complications were a pressure spike leading to loss of light perception, corneal graft rejection, and graft failure. The most common postoperative problem was surgically induced irregular corneal astigmatism.
Ophtec iris reconstruction lens implantation and simultaneous PK reduced visual disturbances and improved the aesthetic appearance of the eyes. The long-term safety of the procedure, judged by BCVA and postoperative complications, was mixed, with both good and bad outcomes.
确定在获得性部分或完全无虹膜眼中联合植入虹膜重建晶状体(Ophtec)和穿透性角膜移植术(PK)的功能及美容效果。

在一项前瞻性非随机单中心干预性病例系列研究中,疗效指标包括美容改善情况以及眩光、星芒和畏光症状的减轻。安全性指标包括最佳矫正视力(BCVA)的变化、不良事件报告及手术并发症。
研究中的9只眼有穿透性或钝性外伤史,为无晶状体眼或需要进行白内障手术。需要进行角膜移植的角膜病变包括瘢痕形成、失代偿或先前移植失败。术后,所有患者对术眼的美容改善情况感到满意,且均报告视觉干扰有所减轻。在最后一次随访检查时,4例患者的BCVA提高,5例患者的BCVA下降。报告了3起不良事件。术中无手术并发症。最严重的术后并发症是眼压急升导致光感丧失、角膜移植排斥反应和移植失败。最常见的术后问题是手术引起的角膜不规则散光。
植入Ophtec虹膜重建晶状体并同时进行PK可减轻视觉干扰并改善眼部美观。根据BCVA和术后并发症判断,该手术的长期安全性有好有坏。
