可植入后房型接触人工晶状体矫治中高度近视临床应用

【目的】研究有晶状体眼可植入后房型接触人工晶状体矫治中、高度近视的效果和安全性。【方法】术前充分扩大瞳孔,倍诺喜眼液表面麻醉,9点透明角膜缘用一次性3 mm角膜切开刀做隧道切口,前房注入黏弹剂,植入折叠式人工晶状体,置于透明晶状体与虹膜之间,吸出黏弹剂后用卡米可林注射液缩瞳,在11点或1点处虹膜根部做部分切除。【结果】中、高度近视21例38眼,术前屈光度-4--22.6 D,其中2眼-4 D。38眼术后24 h均达到术前最佳矫正视力。【结论】可植入后房型接触人工晶状体是在保留透明晶状体的基础上植入的人工晶状体,角膜损伤小,保留生理性调节,具有可逆性,预测性好,术后视力恢复快,适用屈光范围广等优点,这种新方法的应用将开辟屈光手术治疗的新前景。

Clincal application on implantable collamer lens implantation for high myopia

【Objective】To study the efficacy and safety of implantable collamer lens（ICL）implantation for the correction of monderate and high myopia.【Methods】Prior to surgery,the pupils were enlarged adequately and topical anesthesia was andministered with Benoxil.Firstly,two small openings at the base of the cornea to be used to position the lens were created.Next,healon was placed inside the eye to protect the cornea and the natural lens during ICL placement.ICL was impanted between iris and natural lens.Then healon were removed and pupil reduced.Iridoctomy was administerd at last.【Results】Thirty-eight eyes of twenty-one patients with moderate to high myopia（between-4 to-22.6 diopters）had an ICL implanted.All the patients reached corrected visual acuity in 24 hours postoperatively.【Conclusions】ICL implantation is administered on the basis of preserving the natural lens.It is predictable,safe,and effective in the correction of high myopia,and its indications should be carefully selected.
