透明角膜切口有晶状体眼虹膜夹型人工晶状体植入治疗高度近视

目的：研究透明角膜切口有晶状体眼虹膜夹型人工晶状体植入治疗高度近视的临床疗效和安全性。

方法：对20例28眼高度近视患者表面麻醉下行透明角膜切口虹膜夹型人工晶状体植入术，观察术中和术后并发症、术后视力、眼压、屈光度数、角膜内皮计数、人工晶状体稳定性及晶状体混浊情况。

结果：高度近视患者28眼均顺利植入了虹膜夹型人工晶状体，术中无并发症发生，术后裸眼视力均达到或超过术前最佳矫正视力。术后随访6mo，所有植入的人工晶状体均基本位于正位，无明显倾斜、偏位。未发现白内障、葡萄膜炎、黄斑囊样水肿及视网膜脱离等并发症。

结论：在具备熟练的眼科显微手术技巧的前提下，有晶状体眼虹膜夹型人工晶状体植入，有较好的预测性及稳定性，可获得满意的术后视力，术后并发症较少，是治疗高度近视患者安全、有效的方法。

Phakic iris-claw intraocular lens implantation for correction of high myopia with clear corneal incision

AIM: To investigate the safety and therapeutic effectiveness of phakic iris-claw intraocular lens implantation for correction of high myopia with clear corneal incision.

METHODS: Implantation of phakic iris-claw intraocular lens through clear corneal incision was performed on 28 eyes of 20 high myopic patients under topical anaesthesia. Intraoperative and postoperative complications, visual acuity, intraocular pressure, refractive diopter, corneal endothelium, the stable of intraocular lens and the turbid level of lens were observed.

RESULTS: All cases were smoothly implanted iris-claw intraocular lens. No complications were found during the operation. The uncorrected visual acuity of post-operation was better than the best corrected visual acuity of pre-operation. The follow-up time lasted for 6mo, and the intraocular lens in all the eyes were basically in the normal position without tilting and obvious deviation. No serious complications such as cataract, uveitis, cystoid macular edema, retinal detachment were seen in all cases.

CONCLUSION: On the basis of having adept microsurgery technology, phakic iris-claw intraocular lens implantation is predictable and stable, and post-operation visual acuity is satisfying with few complications. It is a safe and effective way to treat high myopia.
