巩膜固定后房型人工晶状体植入术的临床观察

目的：观察巩膜固定后房型人工晶状体植入术治疗玻璃体切除后无囊膜支撑的无晶状体眼的效果。

方法：回顾分析采用巩膜固定后房型人工晶状体植入术治疗的14例14眼患者资料。在2：00，8：00位角膜缘后1.5mm处巩膜瓣下穿刺引出三片式折叠人工晶状体的双襻，将襻插入预制巩膜隧道内固定，缝合巩膜瓣覆盖穿刺口及襻。

结果：患者14例均顺利植入人工晶状体，术后随访6～12mo，患者视力提高、人工晶状体位置稳定、眼压正常、无重大并发症。

结论：应用巩膜固定后房型人工晶状体植入术治疗无囊膜支撑的玻璃体切除后无晶状体眼安全性高，操作简便，疗效确切，值得进一步观察与实践。

Clinical observation of scleral fixation posterior chamber intraocular lens implantation

AIM: To observe the effect of scleral fixation posterior chamber intraocular lens implantation in the treatment of aphakia without capsule supporting after vitrectomy.

METHODS: A retrospective analysis was conducted in 14 patients(14 eyes)who had scleral fixation posterior chamber intraocular lens implantation. Loops of the three-piece foldable intraocular lens were lead from incisions beneath the scleral flap at 2 and 8 o'clock part from the corneal limbus 1.5mm and it was fixed in the pre-made scleral tunnels. Finally, scleral flap were sutured so as to cover the punctures and loops.

RESULTS: Fourteen patients were successfully implanted intraocular lens. Follow-up from 6 to 12 months, all patients received the improved visual acuity, stable IOL position, normal intraocular pressure and no other complications.

CONCLUSION: Scleral fixation posterior chamber intraocular lens implantation is a safe, simple, effective method to treat aphakia without capsule supporting after vitrectomy and worthy further observation and practice.
