玻璃体切除术后无晶状体眼二期前房型人工晶状体植入术

目的：总结54例玻璃体切除后无晶状体眼二期前房型人工晶状体植入术的临床方法和疗效。方法：分别采用传统角巩膜缘切口（31只眼）和巩膜隧切口（23只眼）行二期前房型人工晶状体植入术。术后随访时间3－21个月。结果：54例患者术后裸眼视力均达到或接近术前矫正视力,其中术后裸眼视力＞1．0者11只眼,术后矫正视力＞1．0者16只眼。采用巩膜隧道切口行二期前房型人工晶状体植入术,手术过程平稳;与传统角巩膜切口比较,术中眼压维持稳定．,术后手术性角膜散光度较小。结论：采用传统角巩膜缘切口和巩膜隧道切口行二期前房型人工晶状体植入术,手术效果均良好,两种手术切口比较,以巩膜隧道切口行二期前房型人工晶状体植入术更加安全,可靠、有效。

Implantation of stage II anterior chamber intraocular lens in aphakic eye after vitrectomy

OBJECTIVE: To sum up the clinical methods and results of stage II anterior chamber intraocular lens (AC-IOL) implantation in 54 aphakic eyes after vitrectomy. METHODS: Traditional corneoscleral limbal and tunnel incision were respectively used to perform stage II AC-IOL implantation separately in 54 aphakic eyes following vitrectomy. RESULT: All 54 eyes had obtained good visual acuity and reached the corrected visual acuity before operation. The naked visual acuity of 11 eyes was >/= 1.0, and the corrected visual acuity of 16 eyes, >/= 1.0. CONCLUSIONS: Two methods of implantation of AC-IOL in aphakic eye after vitrectomy all obtain good results. Tunnel incision can make the surgery process easier and induce corneal astigmatism smaller. The bracket function of vitreous body after vitrectomy disappears. This technique can maintain IOP very well during the operation and make the operation safer.
