目的:探讨无巩膜瓣经睫状沟缝线固定后房型人工晶状体(PC-IOL)的手术方法及其临床疗效。方法:对无晶状体囊膜支撑患者15例15眼进行无巩膜瓣经睫状沟固定的PC-IOL植入手术,巩膜外缝线采用巩膜层间"W"字形穿行、末端烧灼固定法。一期手术5例,二期手术10例。术后随访0.5～3(平均1.8)a,观察视力恢复、缝线位置及并发症的情况。结果:视力≥0.5者10眼(67%),术中少量出血4眼(27%),人工晶状体偏斜3眼(20%),黄斑囊样水肿2眼(13%);无1例发生缝线暴露或滑脱。结论:在无晶状体囊膜支撑时,无巩膜瓣经睫状沟缝攀缝线固定PC-IOL是一种安全有效的手术方法。

AIM:To discuss the surgery and its clinical efficacy of non-scleral flap suture fixation of posterior chamber intraocular lens(PC-IOL) through ciliary sulcus.METHODS:A Total of 15 eyes without the support of lens capsule underwent non-scleral flap suture fixation of PC-IOL implantation through ciliary sulcus,using scleral interlayer "W"-shaped walking through and the fixed method of end burning for external scleral suture.It was primary surgery in 5 eyes,secondary surgery in 10 eyes.Patients were followed up for 0.5 to 3 years,an average of 1.8 years,to observe the visual acuity,suture location and complications.RESULTS:Vision ≥0.5 was in 10 eyes(67%),little intraoperative bleeding in 4 eyes(27%),oblique intraocular lens in 3 eyes(20%),cystoid macular edema in 2 eyes(13%);there was no 1 case of suture exposure or slippage.CONCLUSION:In the absence of lens capsule support,non-scleral flap suture fixation of PC-IOL through ciliary sulcus is a safe and effective surgical method.
