目的评价小切口（６ｍｍ）白内障摘出及后房型人工晶状体植入术的疗效。方法对３８例老年性、外伤性白内障施行小切口白内障摘出及后房型人工晶状体植入术。结果术后１ｗｋ裸眼或矫正视力０．５者占７１．１％，３ｍｏ占９４．７％．术后１ｗｋ散光为１．８５±０．９５Ｄ；术后３ｍｏ散光０．９２±０．５８Ｄ，分别小于１０～１２ｍｍ大切口对照组（Ｐ＜０．００１）。内皮细胞损失率为１１．７２％．并讨论手术方式的选择以及术中意外的处理方法。结论小切口白内障摘出及后房型人工晶状体植入术具有实用价值。
Objective To evaluate the efficacy of small incision (6mm) cataract extraction and posterior chamber intraocular lens implantation. Methods Thirty-eight cases of senile and traumatic cataract were performed small incision cataract extraction and posterior chamber intraocular lens implantation. Results 1wk postoperation or correction of visual acuity 0.5 accounted for 71.1%, 3mo 94.7%. The postoperative astigmatism was 1.85 ± 0.95D at 1wk. The astigmatism was 0.92 ± 0.58D at 3 months after operation, less than 10 ~ 12mm large incision control group (P <0.001). The rate of endothelial cell loss was 11.72%. And discuss the choice of surgical methods and intraoperative accidental treatment. Conclusion Small incision cataract extraction and posterior chamber intraocular lens implantation has practical value.
