玻璃体切割术后无晶状体眼行前房灌注下Ⅱ期IOL缝线固定术

Aphakia eye secondary posterior chamber intraocular lens implantation with suture fixation under anterior chamber irrigation after vitrectomy

目的:探讨前房灌注下玻璃体切割术后无晶状体眼Ⅱ期人工晶状体(IOL)缝线固定术的方法及疗效。方法:对30例30眼玻璃体切割术后6～12mo无晶状体眼的患者行前房灌注下后房人工晶状体缝线固定术,术后随访1.5a。结果:患者30例30眼在前房灌注下,成功实施了后房缝线固定IOL植入术,术中出现睫状体出血1例,术后玻璃体出血1例,脉络膜脱离2例。所有患者术后视力均得到提高,视力≥0.3者24例(80%),其中视力≥0.5者8例(27%);视力<0.3者6例(20%),其中视力<0.1者2例(7%)。结论:前房灌注下行此类手术,术中眼压控制稳定,手术效果可靠,术后并发症少,是治疗玻璃体切割术后无晶状体眼、恢复视功能的可靠手术方法。

AIM： To study the methods and effect of aphakia eye secondary posterior chamber intraocular lens（IOL）implantation with suture fixation under anterior chamber irrigation after vitrectomy.METHODS： Thirty aphakia eyes underwent secondary posterior chamber IOL implantation with suture fixation under anterior chamber irrigation after vitrectomy. All the cases were followed up for 1.5 years.RESULTS： Thrity cases（30 eyes）underwent posterior chamber IOL implantation successfully. The complications included hemorrhage of the ciliary body（1 case）in the operation and vitreous hemorrhage（1 case）and choroid detachment（2 cases）after the operation. The visual acuity of all cases was more improved than before, 24 cases（80%）had obtained post-operative visual acuity ≥0.3, of these, 8 cases（27%）≥0.5; 6 cases（20%）〈0.3, of these, 2 cases（7%）〈0.1. CONCLUSION： The method of anterior chamber irrigation is safe and successful which can obtain stableintraocular pressure during and after the operation and lower complications. The operation is an effective method for improving the visual acuity after vitrectomy.
