To evaluate the results after unilateral sulcus implantation of the Crystalens HD (Bausch & Lomb) accommodative intraocular lens (IOL).
This retrospective interventional case series comprised six eyes from three patients who underwent cataract surgery and bilateral Crystalens HD accommodative IOL implantation. The Crystalens HD was implanted in the bag in one eye (non-sulcus group) and, due to posterior capsule rupture, the lens was positioned in the ciliary sulcus in the fellow eye (sulcus group).
Mean patient age was 66.3 ± 4.9 years (range: 60 to 72 years). Mean follow-up was 14.3 ± 3.2 months (range: 12 to 18 months) for the non-sulcus group and 14 ± 2 months (range: 12 to 16 months) for the sulcus group. Uncorrected distance visual acuity improved from 20/100 to 20/33 in the non-sulcus group and from 20/63 to 20/32 in the sulcus group during last follow-up. Corrected distance visual acuity improved from 20/35 to 20/20 in the non-sulcus group and from 20/27 to 20/23 in the sulcus group. Regarding near vision, all eyes in the sulcus group and 66.7% of eyes in the non-sulcus group achieved J1-J2 (Birkhauser reading chart). None of the eyes had any intra- (except posterior capsule rupture in the sulcus cases) or postoperative complications.
Based on this small series, ciliary sulcus implantation of the Crystalens HD seems to be associated with no significant morbidity and provides satisfactory visual acuity outcomes.
评估 Crystalens HD(博士伦)可调节人工晶状体在单侧巩膜下植入的效果。
本回顾性干预性病例系列研究纳入了 3 名患者的 6 只眼,这些患者均接受了白内障手术和双侧 Crystalens HD 可调节人工晶状体植入术。在一只眼(非巩膜下组)中将 Crystalens HD 植入囊袋内,而在对侧眼(巩膜下组)中由于后囊破裂,晶状体被置于睫状沟内。
平均患者年龄为 66.3 ± 4.9 岁(范围:60 至 72 岁)。非巩膜下组的平均随访时间为 14.3 ± 3.2 个月(范围:12 至 18 个月),巩膜下组为 14 ± 2 个月(范围:12 至 16 个月)。在末次随访时,非巩膜下组的未矫正远视力从 20/100 提高至 20/33,巩膜下组从 20/63 提高至 20/32。非巩膜下组的矫正远视力从 20/35 提高至 20/20,巩膜下组从 20/27 提高至 20/23。在近视力方面,巩膜下组的所有眼和非巩膜下组的 66.7%的眼均达到 J1-J2(Birkhauser 阅读图表)。两组均无任何眼内(巩膜下组除外后囊破裂)或术后并发症。
基于这一小样本系列研究,Crystalens HD 睫状沟植入似乎没有显著的发病率,并且提供了令人满意的视力结果。
