Abstract：
OBJECTIVE: To evaluate the visual and refractive outcomes in cases after sutured scleral fixation of existing subluxated or dislocated acrylic one-piece intraocular lenses (IOLs).
METHODS: This study retrospectively enrolled a consecutive series of patients who underwent a surgery of sutured existing subluxated or dislocated IOLs from October 2018 to June 2020. All patients underwent comprehensive preoperative and postoperative ophthalmologic examination, and data were collected including age, sex, surgical indications, best-corrected visual acuity, refractive error, intraocular pressure. Presence of intraoperative and postoperative surgical complications was documented.
RESULTS: A total of 20 consecutive cases were enrolled for analysis with mean final follow-up period 9.8±5.3mo. Visual acuity improved from a mean of 0.35 (0.46±0.32 logMAR) preoperatively to 0.61 (0.21±0.18 logMAR) at the 3-month follow-up (P=0.002). The mean amount of preoperative keratometric astigmatism and total postoperative refractive astigmatism was -1.24±0.80 diopters (D) and -1.42±0.97 D, respectively. There was no statistically significant difference between preoperative and postoperative astigmatism (P=0.156). The mean IOL-induced astigmatism was -0.23±0.53 D. The mean spherical equivalent at the 3-month follow-up was -0.1±0.94 D. No major complications were noted during the follow-up period.
CONCLUSIONS: Surgical techniques using sutured scleral fixation of existing subluxated or dislocated acrylic one-piece IOLs result in favorable visual and refractive outcomes without major complications.

摘要：
目的：评估现有的半脱位或脱位丙烯酸单片人工晶状体（IOL）的巩膜缝合固定后的视觉和屈光结果。
方法：本研究回顾性纳入了连续的一系列患者，这些患者于2018年10月至2020年6月接受了现有的半脱位或脱位人工晶状体的缝合手术。所有患者均接受术前、术后全面的眼科检查,收集的数据包括年龄，性别,手术适应症,最佳矫正视力，屈光不正,眼内压。记录了术中和术后手术并发症的存在。
结果：共纳入20例连续病例进行分析，平均最终随访时间为9.8±5.3mo。视力从术前的平均0.35（0.46±0.32logMAR）提高到3个月随访时的0.61（0.21±0.18logMAR）（P=0.002）。术前角膜散光和术后总屈光度平均为-1.24±0.80屈光度（D）和-1.42±0.97D，分别。术前、术后散光差异无统计学意义(P=0.156)。平均IOL引起的散光为-0.23±0.53D。3个月随访时的平均球面当量为-0.1±0.94D。
结论：使用缝合巩膜固定术对现有的半脱位或脱位的丙烯酸单片IOL的手术技术可获得良好的视觉和屈光效果，而没有重大并发症。
