A 29-year-old man presented to us with bilateral pseudophakia with suboptimal vision in right eye. His uncorrected distance visual acuity (UDVA) on Snellen's chart was 6/36 and 6/9 in right eye (OD) and left eye (OS), respectively. It improved to 6/9 OD with -5.00DS/-0.50DC at 90° and 6/6 OS with -0.5DC at 100°. He had undergone buckling surgery 1 year back for rhegmatogenous retinal detachment in right eye and subsequently developed a myopic refractive error. A spherical piggyback intraocular lens (IOL; Rayner Sulcoflex, East Sussex) was implanted in the sulcus for refractive correction. The postoperative UDVA at 4 weeks was 6/6p. The intraocular pressure was normal and there was no significant endothelial cell loss. Piggyback IOLs can be an effective tool to correct the induced refractive error due to an increase in axial length following buckling surgery.
一名29岁男性前来就诊,双眼为人工晶状体眼,右眼视力欠佳。他在斯内伦视力表上的右眼未矫正远视力(UDVA)为6/36,左眼为6/9。右眼通过-5.00DS/-0.50DC×90°矫正后视力提高到6/9,左眼通过-0.5DC×100°矫正后视力提高到6/6。他1年前因右眼孔源性视网膜脱离接受了巩膜扣带术,随后出现了近视屈光不正。为了进行屈光矫正,在睫状沟植入了一枚球性后房型人工晶状体(IOL;Rayner Sulcoflex,东萨塞克斯)。术后4周的UDVA为6/6p。眼压正常,且没有明显的内皮细胞丢失。后房型人工晶状体可以作为一种有效的工具,用于矫正巩膜扣带术后因眼轴长度增加而引起的屈光不正。
