虹膜膈人工晶状体用于治疗外伤性白内障伴虹膜缺损的临床观察

Clinical observation of black diaphragm intraocular lens with iridal septum to cure traumatic cataract accompanied by iridocoloboma or aniridia

目的:分析虹膜膈人工晶状体植入术对外伤白内障合并无虹膜或虹膜大部分缺损患者的临床效果。方法:采用植入带虹膜膈人工晶状体治疗9例9眼无虹膜或大部分无虹膜的外伤性白内障患者,观察视力及各种手术并发症。结果:全部病例带虹膜膈人工晶状体植入成功,术后视力均有不同程度提高(指数/眼前～0.6),8例畏光症状全部消除,1例明显减轻。1例人工晶状体襻折断,3例发生睫状体少量出血,3例角膜水肿,5例葡萄膜炎,4例继发性青光眼,1例大泡性角膜炎。结论:带虹膜膈人工晶状体对无虹膜或大部分虹膜缺损的外伤性白内障患者提供了一个行之有效的治疗方法。

AIM：To analyze the clinical effect of black diaphragm intraocular lens （IOL） implantation for the treatment of traumatic cataract accompanied by iridocoloboma or aniridia. METHODS： IOL with iridal septum was implanted into 9 eyes of 9 cases with traumatic cataract accompanied by iridocoloboma or aniridia. The preoperative and post-operative visual acuities and surgical complications were observed respectively.RESULTS：We performed the operation successfully in each patient. The visual acuities in patients were improved at various degrees. Photophobia disappeared in 8 patients and decreased in 1 patient. Intraoperatively, haptic rupture occurred during lens insertion in one case, ciliary sulcus bleeding in 3 cases, transient postoperative corneal endothelial edama in 3 eyes, uveitis in 5 eyes, secondary glaucoma in 4 eyes and bullous keratopatitis in 1 eye.CONCLUSION：Implantation of IOL with iridal septum proved to be an effective treatment for traumatic cataract combined with iridocoloboma or aniridia.
