目的 评价改良的小切口非超声乳化白内障摘出人工晶状体植入术的效果 ,并与常规白内障囊外摘出术对比。方法 在显微镜下 ,同种材料进行两种手术 3 8眼及 80眼。术后 1月进行视力与角膜散光的测定。结果 前者术后矫正视力 0 5～ 0 8者 15 7% ,1 0以上者 84 2 % ,术后散光与术前无显著差异 ;后者术后矫正视力 0 5～ 0 8者 3 3 8% ,1 0以上者 62 5 % ,术后散光与术前有显著差异。结论 小切口手术视力恢复快 ,较超声乳化手术成本低 ,不失为一种较好的手术方法。
Objective To evaluate the effect of modified small incision non-phacoemulsification cataract extraction and intraocular lens implantation compared with conventional extracapsular cataract extraction. Methods under the microscope, the same kind of material for the two kinds of surgery 38 eyes and 80 eyes. Visual acuity and corneal astigmatism were measured at 1 month after surgery. Results The former postoperative visual acuity 0 5 ~ 0 8 15 7%, more than 10 84 2%, postoperative astigmatism and preoperative no significant difference; the latter postoperative corrected visual acuity 0 5 ~ 0 8 3 3 8% , More than 10% 62 5%, postoperative astigmatism and preoperative significant differences. Conclusions Small incision surgeries have faster visual acuity and lower cost than phacoemulsification, which is a good surgical method.
