屈光性晶体置换术矫正中老年高度近视的临床观察

目的临床观察应用超声乳化技术摘除尚透明的晶状体后植入后房型人工晶体矫正中老年高度近视眼的有效性和安全性。方法对49例96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后房折叠型人工晶体植入术,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、病人视力习惯和满意程度。结果术后所有患者裸眼视力均提高,≥0.5者88眼(91.67%);最佳矫正视力均达到或好于术前;术后屈光度数预测准确性为70.2%;多焦点晶体植入患者术后脱镜率为85.7%;术中无手术相关的并发症发生;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技术行透明晶状体摘除联合后房型人工晶体植入矫正中老年高度近视眼的方法安全、有效,多焦点人工晶体植入有助于提高患者术后脱镜率,手术远期效果有待进一步研究。

Refractive clear lens extraction and intraocular lens implantation for treatment of high myopia in middle-aged patients

Objective To observe the effectiveness and safety of refractive clear lens extraction and IOL implantation for treatment of high myopia.Methods Phacoemulsification and IOL implantation was performed on 96 eyes of 49 high myopic patients with clear lens.Preoperative and postoperative visual acuity,refractive error,bilateral visual acuity,pre-and postoperative complications were observed.Results Postoperative VA improves,so does the bilateral visual acuity.About 85.7%patients with multifocal IOL never wear sp...
