摘　　要：评价使用超声乳化行透明晶状体摘除和植入折叠人工晶状体治疗高度近视的疗效、预测性和安全性。方法 :对 45例 80只眼行透明角膜切口 ,超声乳化透明晶状体摘除联合折叠人工晶状体植入治疗高度近视。患者年龄 2 5～ 71岁 ,平均 5 5 13± 8 83岁。平均眼轴长度 2 9 45± 2 0 7mm ,平均等效球镜度数 -11 86± 4 73D ,植入人工晶状体屈光度平均值为9 19± 3 80D。随访 6～ 42个月。结果 :术后最佳矫正视力 80只眼均达到或超过术前最佳矫正视力 ;70只眼 (87 5 % )术后裸眼视力达到或超过术前最佳矫正视力 ;44只眼 (5 5 0 % )术后裸眼视力达到 0 5以上 ;术后屈光度平均值为 -1 96± 1 2 8D ,70只眼 (87 5 % )在预矫屈光度±1D内。术中未发生后囊破裂。随访中 11只眼发生后囊混浊 ,未发现视网膜脱离、黄斑囊样水肿等并发症。结论 :透明晶状体摘除治疗高度近视与目前的角膜屈光手术相比 ,可能更适宜于中年以上不愿戴镜和戴镜不能矫治的高度近视眼患者 ,其远期疗效尚需长期随访。Objective:To evaluate the effectiveness,predictability and safety of clear lens extraction by phacoemulsification on high myopia. Methods:Phacoemulsification and foldable intraocular lenses(IOL)implantation were performed on the clear lenses of 80 eyes of 45 patients with high myopia.The average age of the patients was 55 13±8 83 years old(25-71 years old).The mean axial length was 29 45±2 07mm,the mean spherical equivalent was -11 86±4 73D,and the mean diopter of IOL was +9 19±3 80D.The period of follow-up was 6～42 months. Results:The uncorrected visual acuity(UCVA)was improved in all cases after operation.44 eyes(55 0%)achieved 0 5 or better,and UCVA in 70 eyes(87 5%)were equal to or better than their preoperative best corrected visual acuity(BCVA).Mean myopia diopter of 70 eyes(87 5%)was in the range of the predicted diopter ±1D.No capsule tear occurred.11 eyes developed to posterior capsule opacification during follow-up.Retinal detachment,macular edema,glaucoma and IOL decentration were not observed. Conclusions:Clear lens extraction may be a better choice for middle-aged high myopia patients.A longer follow-up is needed to assess the complications completely.
