To evaluate the clinical outcomes of intraocular lens (IOL) exchange in patients with an opacified ACRL-C160 intraocular lens (IOL) using an optic-only removal technique.
Department of Ophthalmology, Soonchunhyang University Hospital, Seoul, Korea.
The study comprised eyes with previous phacoemulsification and implantation of a single-piece hydrophilic acrylic IOL in the capsular bag and subsequent development of severe late opacification of the IOL. In all eyes, the IOL optic was explanted; any haptic with firm adhesions was left in the capsular bag. This was followed by placement of a new IOL. The perioperative complications were evaluated, and the best corrected visual acuity (BCVA) before surgery and after surgery was compared.
Twenty-three eyes of 20 patients were evaluated. Uneventful IOL exchange and placement of a new IOL in the bag was achieved in 9 eyes (39.1%) and in the sulcus in 13 eyes (56.5%), with posterior capsule rupture in 2 eyes (8.7%). One eye (4.3%) developed zonular dehiscence, and scleral IOL fixation was performed. The mean BCVA was 0.64 +/- 0.35 logMAR before IOL exchange and 0.24 +/- 0.20 logMAR after IOL exchange. During 41 months of follow-up, 1 eye (4.3%) each was affected by recurrent anterior uveitis and delayed zonular dehiscence. The final mean BCVA was 0.38 +/- 0.40 logMAR. There was no corneal decompensation or infectious keratitis.
The optic-only removal technique was a safe and helpful procedure that allowed recovery of visual acuity because it decreased the intraoperative complication of zonular dehiscence.
采用仅取出光学部的技术评估植入ACRL-C160型人工晶状体(IOL)且该晶状体已混浊的患者进行IOL置换的临床效果。
韩国首尔顺天乡大学医院眼科。
本研究纳入的患眼此前接受过白内障超声乳化吸除术并在囊袋内植入了单片式亲水性丙烯酸酯IOL,随后IOL出现严重的晚期混浊。所有患眼中,均取出IOL光学部;任何与囊袋牢固粘连的襻均留在囊袋内。然后植入一枚新的IOL。评估围手术期并发症,并比较手术前后的最佳矫正视力(BCVA)。
对20例患者的23只患眼进行了评估。9只眼(39.1%)顺利完成IOL置换并将新IOL植入囊袋,13只眼(56.5%)植入睫状沟,2只眼(8.7%)发生后囊破裂。1只眼(4.3%)出现悬韧带断裂,行巩膜IOL固定术。IOL置换术前平均BCVA为0.64±0.35 logMAR,术后为0.24±0.20 logMAR。在41个月的随访期间,各有1只眼(4.3%)发生复发性前葡萄膜炎和迟发性悬韧带断裂。最终平均BCVA为0.38±0.40 logMAR。未发生角膜失代偿或感染性角膜炎。
仅取出光学部的技术是一种安全且有效的手术方法,可恢复视力,因为它减少了悬韧带断裂这一术中并发症。
