Abstract

Purpose: To evaluate the performance of silicone elastomer lenses in pediatric eyes with aphakia.

Methods: We retrospectively studied pediatric aphakic eyes fit with Silsoft lenses (elastofilcon A, Bausch & Lomb) at the L.V. Prasad Eye Institute, India.

Results: Seventy-four children (106 eyes) with a median age of 9.0 months (range: 1 month to 12 years) were included in the study. Congenital cataract was the pre-existing pathology in 84 eyes. Lenses were fit between 1 week and 5 years following surgical intervention (median: 25 days). The most frequently used base curves were 7.5 mm (n=46 eyes) and 7.7 mm (n=39 eyes); lens diameter was 11.3 mm (n=103 eyes). Satisfactory fit was achieved in 86 eyes (81.1%). One-week extended wear was the most commonly recommended mode of wear (n=95 eyes). Lenses (n=118) were replaced for change of power, lens loss, and deposits or damage. Lenses were worn for > or =6 months in 68 eyes (64.2%). Twenty-three contact lens related adverse events occurred, all of which resolved uneventfully. On survival analysis, the probability of not having a lens related complication was 75.5% (95% CI; 61.5-89.5) at 24 months.

Conclusions: In the management of pediatric aphakia, Silsoft lenses are safe, provide satisfactory optical correction, and are easy to handle. Limited availability and the financial costs associated with frequent lens replacement are limitations in our socioeconomic circumstances.

软性隐形眼镜治疗儿童无晶状体。
目的:评价有机硅弹性体晶状体在儿童无晶状体中的应用效果。方法:我们回顾性研究了印度L.V. Prasad眼科研究所的儿童无晶状体(elastofilcon A, Bausch & Lomb)。结果:74名儿童(106只眼)纳入研究,平均年龄9.0个月(范围:1个月至12岁)。84只眼存在先天性白内障。在手术后1周至5年内(中位数:25天)配戴晶状体。最常使用的基线曲线为7.5 mm (n=46眼)和7.7 mm (n=39眼);晶状体直径11.3 mm (n=103眼)。86只眼(81.1%)吻合满意。一周延长配戴是最常用的配戴方式(n=95眼)。透镜(n=118)因功率变化、透镜丢失、沉积或损坏而更换。68只眼(64.2%)配戴超过6个月。发生23例与隐形眼镜相关的不良事件,均顺利解决。在生存分析中,无晶状体相关并发症的概率为75.5% (95% CI;61.5-89.5)。结论:Silsoft隐形眼镜治疗儿童无晶状体安全,光学矫正效果满意,操作方便。有限的可用性和与频繁更换晶状体相关的财务成本是我们社会经济环境的限制。
