晶状体脱位手术治疗的临床分析

目的:探讨不同手术方式治疗不同程度脱位晶状体的临床效果及安全性。方法:回顾性系列病例研究。收集2018-11/2019-05浙江中医药大学附属第一医院晶状体不全脱位合并白内障的患者11例11眼(男9例,女2例),年龄46~76(60.73±10.63)岁。其中外伤性白内障10眼,原因不详者1眼。根据脱位程度采用不同的手术方式辅助人工晶状体植入,4眼晶状体脱离范围大于270°行人工晶状体悬吊术。4眼脱离范围180°~270°行张力环植入,虹膜拉钩巩膜固定。3眼脱离范围小于180°行5-0聚丙烯线植入囊袋辅助人工晶状体植入,虹膜拉钩巩膜固定。术中视玻璃体脱出情况行前段玻璃体切除。收集患者术前术后视力、眼压。结果:所有眼球均Ⅰ期植入人工晶状体。术后视力显著提高,术前最佳矫正视力从0.77±0.26提升到0.35±0.28。术后患者眼压从24.33±13.55mmHg下降到13.85±3.80mmHg。所有患者无术中并发症发生。结论:晶状体不全脱位合并白内障的手术治疗过程中,个性化的手术方案及灵活的治疗措施,可以使得白内障手术安全、有效地进行。

Retrospective analysis of surgical strategies for lens subluxation

AIM:To analyze the effectiveness and safety of different surgical strategies for cataract combined with subluxated lens.

METHODS: This is a retrospective study. Data are acquired from patients who diagnosed with cataract combined with subluxated lens between November 2018 to May 2019 in the ophthalmological center of the First Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine. There are 11 eyes in 11 patients(9 males and 2 females), 10 eyes were caused by trauma and 1 eye was unknown. Cataract combined with subluxated lens were treated with different surgery procedures according to the degree of dislocation. Four eyes with lens dislocation larger than 270° underwent intraocular lens suspension; Four eyes with lens dislocation about 180° underwent IOL and tension ring implant in capsular, at the same time, the iris hook was hooked to the lens capsule bag and fixed to the sclera. Three eyes with lens dislocation less than 180° underwent IOL implantation combined with 5-0 polypropylene suture, iris hook was also hooked to the lens capsule bag and fixed to the sclera. If the anterior chamber has vitreous prolapse, anterior vitrectomy was performed. Best corrected visual acuity(BCVA)and intraocular pressure(IOP)were observed before and after surgery.

RESULTS: All eyes were successfully implanted with intraocular lens(IOL). Best corrected visual acuity(LogMAR)increased from 0.77±0.26 to 0.35±0.28. Mean IOP decreased from 24.33±13.55 to 13.85±3.80mmHg. No intraoperative complications occurred in all cases.

CONCLUSION: In the treatment of lens dislocation with cataract, individualized surgical plan and flexible treatment measures can make cataract surgery safe and effective.
