有晶状体眼后房型人工晶状体植入治疗高度近视的临床观察

目的探讨有晶状体眼后房型人工晶状体（ICL／TICL）植入术矫正高度近视的有效性和安全性。方法选择高度近视8例（15只眼），平均年龄（25．56±3．2）岁，经术前检查后符合入选标准，屈光状态稳定1年以上。14只眼矫正视力≥0．8，1只限0．6。11只眼行ICL植入，4只眼行TICL植入。结果15只眼中14只眼术后裸眼远视力等于或大于术前最佳矫正视力（93．33％），术后1d裸眼远视力≥1．0者10只眼（66。7％），0．5—0．8者4只眼（26．7％），0．4者1只眼（6．67％）；随访6个月时矫正视力，12只眼≥1．0，2只眼为0．8，1只眼为0．6。4只眼TICL经随访6个月，散光轴偏差均〈10°。本组病例未发现前囊下晶状体局限性混浊。术后角膜内皮细胞计数及前房深度未见明显变化。结论有晶状体眼后房型人工晶状体植入预测性好，视力恢复迅速，无回退，无严重并发症，适用屈光度范围广，特别适用于不适合准分子激光手术的高度近视患者。

Clinical research of the implantation of ICL/TICL for the correction of extreme myopia

Objective To investigate the efficacy and safety of the implantation of implantable contact lens(ICL) /toric implantable contact lens(TICL)for the correction of extreme myopia.Methods This study included 15 eyes of 8 patients with-8.5~15.5 diopters of myopia,in which 11 eyes were treated with ICL implantation,and 4 with TICL.Result After operation,naked vision of 14 eyes(93.33%) was the same or better than the pre-operative best vision.At the first day after operation,there were 10 eyes(66.7%)got naked vision increased to 1.0 or even better.with 4 eyes(26.7%)to 0.5~0.8,1 eye(6.67%)to 0.4.After 6 month,there were 12 eyes got naked vision increased to 1.0 or even better,2 eyes to 0.8,1 eye to 0.6.There were 4 eyes happened increased intraocular pressure in early days after operation,the intraocular pressure became normal soon after positive treatment.The astigmatism axis deviations of the 4 eyes which were treated with TICL implantation were all less than 10°.After operation,there was no limited lens opacities of anterior subcapsular,and the anterior chamber depth intraocular pressure and corneal endothelium counting before and after the operation had no significant difference.Conclusion The implantation of phakic posterior chamber ICL/TICL to correct high myopia was a predictable method which can increase vision rapidly,with no regression and serious complication.It is a suitable treatment method for high myopia,especial1y for patients who was not suitable for LASIK,with a wide range of diopters.
