目的:临床观察应用超声乳化技术摘除尚透明的晶状体后,行ReSTOR多焦点人工晶状体的屈光性晶状体置换术矫正中老年高度近视眼的有效性和安全性。方法:对26例44眼,45岁以上晶状体尚透明的高度近视眼患者行超声乳化透明晶状体摘除联合ReSTOR多焦点人工晶状体植入术,观察手术前后的视力、屈光状态、角膜曲率、眼压、内皮细胞计数、立体视觉、脱镜率、患者视力习惯和满意程度。结果:术中无并发症发生。术后患者裸眼及最佳矫正远近视力、角膜曲率、立体视觉等均较术前提高,术后脱镜率达95.5%,满意程度97.7%。术后除一过性眼压增高外,随访期内未出现后囊膜混浊,未发现黄斑囊样水肿及视网膜脱离等并发症。结论:以成熟的超声乳化手术技术行透明晶状体摘除联合ReSTOR多焦点人工晶状体植入矫正中老年高度近视眼的方法是安全和有效的,其远期效果有待进一步研究。

AIM:To observe the effectiveness and safety of clear lens extraction and Acrysof ReSTOR multi-focal intraocular lens(IOL) implantation to correct high myopia in middle-and old-aged patients.METHODS:Phacoemulsification and implantation of Acrysof ReSTOR multi-focal IOL were performed on 44 eyes of 26 high myopic patients with clear crystalline lens.Preoperative and postoperative visual acuity,refractive error,corneal curvature,IOP,endothelial cell counting,stereoscopic vision,spectacles independent rate,vision habit,and satisfaction,of the patients were observed.RESULTS:No complications occurred intraoperatively.Postoperative uncorrected and best-corrected distant and near visual acuity,corneal curvature,and stereoscopic vision all improved than before surgery about 95.5% patients never wore spectacles,and 97.7% patients were satisfied with the refractive results.After operation,except for a transient increased intraocular pressure,no posterior capsular opacification,cystoid macular edema and retinal detachment were found during the follow-up period.CONCLUSION:Clear lens phacoemulsification and Acrysof ReSTOR multi-focal IOL implantation to correct high myopia in middle-and old-aged patients is a safe,effective procedure serving as a refractive surgery.Further follow-up over a longer period is needed to fully assess the effectiveness and complications of this operation.
