To evaluate the suitability and safety of a black diaphragm posterior chamber intraocular lens (IOL).
Department of Ophthalmology, Leeds General Infirmary, Leeds, United Kingdom.
Seven patients who had secondary implantation of a Morcher 67G black diaphragm posterior chamber IOL were identified. All patients were men with a mean age of 42 years who had previous ocular trauma resulting in extensive loss of iris tissue (traumatic aniridia). Simultaneous penetrating keratoplasty was performed in 4 cases. Minimum follow-up was 10 months (mean 19 months).
Best corrected visual acuity improved in 5 cases and was unchanged in 1 case. The lens was well centered in 5 cases. Two cases developed secondary glaucoma, 1 requiring trabeculectomy. One case developed infective endophthalmitis but had a visual acuity of 6/18 at last follow-up, and 1 had a vitreous and anterior chamber hemorrhage, which resolved.
The black diaphragm posterior chamber IOL overcame aphakia in eyes with considerable loss of iris tissue and may mitigate the visually disabling effects of traumatic aniridia. Although this lens appears safe, caution should be used in its implantation until more patients with longer follow-up are studied.
评估黑色人工晶状体后房型人工晶状体（IOL）的适用性和安全性。
英国利兹利兹总医院眼科。
确定7例接受Morcher 67G黑色人工晶状体后房型人工晶状体二次植入的患者。所有患者均为男性，平均年龄42岁，既往有眼外伤导致虹膜组织广泛缺失（外伤性无虹膜）。4例同时行穿透性角膜移植术。最短随访时间为10个月（平均19个月）。
5例最佳矫正视力提高，1例不变。5例晶状体位置居中良好。2例发生继发性青光眼，1例需要行小梁切除术。1例发生感染性眼内炎，但最后一次随访时视力为6/18，1例发生玻璃体和前房出血，出血已吸收。
黑色人工晶状体后房型人工晶状体克服了虹膜组织大量缺失眼的无晶状体状态，并可能减轻外伤性无虹膜的视力致残影响。尽管这种晶状体似乎安全，但在对更多患者进行更长时间随访研究之前，植入时应谨慎。
