目的采用玻璃体腔内套结法处理脱位至后玻璃体腔内的后房型人工晶状体(IOL),并对手术效果进行观察.方法回顾性病例研究.对12例IOL脱位至玻璃体腔的患者行玻璃体切除术后玻璃体腔内复位固定后房型IOL,术后随访6～61个月,观察手术前、后患者的视力情况和并发症.结果 12例患者术后最佳矫正视力为0.02～1.0,IOL位置在随访期间无改变.所有病例术后均有不同程度角膜水肿,5例早期眼压偏低,2例出现一过性眼压增高,1例出现前房纤维素性渗出.2例术后发生视网膜脱离,行巩膜外环扎术成功复位.结论玻璃体腔内IOL固定术无需取出IOL,可以减少对眼球的创伤及切口源性角膜散光,是处理IOL脱位于玻璃体腔简单、有效的方法.

Objective Using intraocular cow hitch knots to fix the luxated intraocular lens (IOL) in the vitreous cavity without IOL extraction,and observe the effect of the surgery.Methods It was a retrospective case series study.A three-port vitrectomy were using to suture the IOL which were dislocated in the vitreous cavity.After the vitrectomy,intraocular cow hitch knots were used to fixate the IOL haptics in 12 patients with a luxated IOL in the vitreous cavity.Patients were followed up for 6～61 months,visual acuity and surgical complications associated with the procedure were evaluated after the surgery.Results The postoperative best-corrected visual acuity (BCVA) of 12 patients were 2/100 to 20/20.In all 12 cases,the IOL fixated stably and remained well positioned during the follow-up.Postoperative complications included corneal edema in all eyes,ocular hypotension in 5 eyes,temporary ocular hypertension in 2 eyes,and fibrin exudates in the anterior chamber in 1 eye.Retinal detachment was observed in 2 cases,which were reattached by scleral buckling.Conclusion Fixating the IOL in vitreous cavity directly after vitrectomy using intraocular cow hitch knots enables secure fixation of the luxated IOL in the vitreous without extracting it.This technique is the simplest and most effective method for management of IOL dislocation into vitreous cavity.
