To compare the functional outcome of retropupillary iris claw lenses (RPIC-IOL) and scleral fixated intraocular lenses (SFIOL) in children with large lens subluxations.
Sixty eyes of patients between 6 and 18 years of age having >7 clock hour lens subluxation were included and equally divided into group A (RPIC-IOL implantation) and group B (Gore-Tex sutured SFIOL implantation). Cases with anterior and posterior segment abnormalities, trauma and glaucoma were excluded. Primary outcome was improvement in best-corrected visual acuity (BCVA) at 1.5 years. Secondary outcomes were assessment of intraocular lens (IOL) tilt, mean change in astigmatism at 1.5 years, and median operating time. All surgeries were performed by the same surgeon.
The mean improvement in BCVA in group A was 0.28 ± 0.41 logMAR and group B was 0.44 ± 0.45 logMAR (P = 0.3). Significant IOL tilt was seen in 4 eyes in group A (13.33%) and 5 eyes in group B (16.66%) (P = 0.120). Mean change in astigmatism was 4.38 ± 5.9D in group A and 4.91 ± 4.4D in group B (P = 0.299). The median operating time was 40 min in group A and 90 min in group B (P < 0.001). No significant posterior segment complications were seen in either technique.
Both procedures had comparable visual outcomes. RPIC-IOL implantation was relatively quick and comparatively easier; it may be preferred in cases with high risk of retinal detachment.
比较后房虹膜夹型人工晶状体(RPIC-IOL)和巩膜固定型眼内晶状体(SFIOL)在大晶状体脱位儿童中的功能结果。
纳入年龄在 6 至 18 岁之间、晶状体脱位超过 7 个时钟小时的 60 只眼患者,并将其平均分为 A 组(RPIC-IOL 植入)和 B 组(Gore-Tex 缝线巩膜固定 SFIOL 植入)。排除具有前节和后节异常、创伤和青光眼的病例。主要结局是 1.5 年时最佳矫正视力(BCVA)的改善。次要结局是评估人工晶状体(IOL)倾斜度、1.5 年时平均散光变化和中位数手术时间。所有手术均由同一位外科医生进行。
A 组 BCVA 的平均改善为 0.28 ± 0.41 logMAR,B 组为 0.44 ± 0.45 logMAR(P = 0.3)。A 组有 4 只眼(13.33%)和 B 组有 5 只眼(16.66%)出现明显的 IOL 倾斜(P = 0.120)。A 组的平均散光变化为 4.38 ± 5.9D,B 组为 4.91 ± 4.4D(P = 0.299)。A 组的中位数手术时间为 40 分钟,B 组为 90 分钟(P < 0.001)。两种技术均未出现明显的后节并发症。
两种手术方法均具有相似的视觉效果。RPIC-IOL 植入术相对较快且操作相对简单;在存在视网膜脱离高风险的情况下,可能更倾向于使用该手术。
