To describe our technique for secondary intraocular lens (IOL) implantation in aphakic children and report patient outcomes.
In our technique for in-the-bag IOL implantion, we used a microvitreoretinal (MVR) blade to separate the capsular leaflets for aspiration of reproliferated lens material within Soemmering's ring. When sufficient capsular opening was not possible or capsular support deemed inadequate, an IOL was implanted in the sulcus. Records of patients with secondary IOL implantation between 1999 and 2009 were retrospectively reviewed with regard to intra- and postoperative complications and visual and refractive outcomes.
A total of 50 consecutive eyes of 32 patients were evaluated. Mean age at secondary IOL implantation was 9.1 years. Of these, 26 eyes had in-the-bag IOLs and 24 had sulcus IOLs. Forty-four eyes (88%) had an AcrySof IOL (Alcon Inc, Ft. Worth, TX). The prevalence of any corneal edema (54% vs 19%, P = 0.04) and uveal inflammation >2+ (92% vs 31%, P < 0.05) in immediate postoperative period was greater with sulcus IOL than in-the-bag placement. Late inflammation at 6 months developed in 1 eye, and glaucoma developed in 2 eyes with sulcus IOLs. All eyes maintained or gained lines of best-corrected visual acuity. Mean absolute prediction error was 0.9 ± 0.9 with no significant difference between in-the-bag and sulcus placement.
Eyes achieving secondary in-the-bag IOL showed less inflammation and corneal edema in the early postoperative period partly as the result of greater surgical and anatomic challenges in some eyes receiving sulcus IOL. Visual and refractive outcomes were satisfactory in eyes with secondary IOL implantation. Mean prediction error was similar for in-the-bag and sulcus IOLs.
描述我们在无晶状体儿童中进行二期人工晶状体(IOL)植入的技术,并报告患者的治疗结果。
在我们的囊袋内IOL植入技术中,我们使用微型玻璃体视网膜(MVR)刀片分离囊膜瓣,以吸出索默林环内再增殖的晶状体物质。当无法获得足够的囊膜开口或认为囊膜支撑不足时,将IOL植入睫状沟。对1999年至2009年间接受二期IOL植入的患者记录进行回顾性分析,内容包括术中及术后并发症以及视力和屈光结果。
共评估了32例患者的50只连续眼。二期IOL植入时的平均年龄为9.1岁。其中,26只眼植入了囊袋内IOL,24只眼植入了睫状沟IOL。44只眼(88%)植入了AcrySof IOL(爱尔康公司,沃思堡,得克萨斯州)。术后即刻,睫状沟IOL植入眼的任何角膜水肿发生率(54%对19%,P = 0.04)和葡萄膜炎>2+的发生率(92%对31%,P < 0.05)均高于囊袋内植入。6个月时,1只睫状沟IOL植入眼发生迟发性炎症,2只睫状沟IOL植入眼发生青光眼。所有眼的最佳矫正视力均保持或提高。平均绝对预测误差为0.9±0.9,囊袋内植入和睫状沟植入之间无显著差异。
二期囊袋内IOL植入眼在术后早期炎症和角膜水肿较少,部分原因是一些接受睫状沟IOL植入的眼面临更大的手术和解剖挑战。二期IOL植入眼的视力和屈光结果令人满意。囊袋内IOL和睫状沟IOL的平均预测误差相似。
