to describe how preoperative and intraoperative positioning techniques can be used to manage subluxed intraocular lenses (IOL) whilst saving patients from pars plana vitrectomy.
An 88-year-old man with a complex past medical history including mild cognitive decline from early Alzheimer's dementia and pertinent ocular history of pseudoexfoliation syndrome and previous cataract surgery with IOL presented with decreased vision secondary to an inferiorly subluxed IOL/bag complex. The IOL was not visible in the operating room when he was supine but was visible in clinic the next day after he had slept in the prone position the night before. The patient was returned to the operating room the next day and a fixation suture was used to capture the IOL while he was upright. The IOL was then fixated to the sclera in standard position.
Both pre and intraoperative positioning techniques can help anterior segment surgeons fixate subluxed IOLs that otherwise seem inaccessible from an anterior approach and thus avoiding the inherent risks associated with vitrectomy.
描述术前和术中定位技术如何用于处理半脱位的人工晶状体(IOL),同时使患者避免接受玻璃体切除术。
一名88岁男性,有复杂的既往病史,包括早期阿尔茨海默病导致的轻度认知功能减退,以及剥脱综合征和既往白内障手术植入IOL的相关眼部病史,因IOL/晶状体囊袋复合体向下半脱位继发视力下降前来就诊。患者仰卧位时,IOL在手术室中不可见,但在前一晚俯卧位睡眠后,第二天在诊所中可见。第二天患者返回手术室,在其直立位时使用固定缝线捕获IOL。然后将IOL固定于标准位置的巩膜上。
术前和术中定位技术均可帮助眼前节外科医生固定半脱位的IOL,否则从前路似乎无法触及这些IOL,从而避免与玻璃体切除术相关的固有风险。
