目的探讨梯形小切口手法碎核摘除白内障及人工晶状体植入的疗效及术后的角膜散光变化。方法对252例(275眼)老年性白内障患者采用百赖皓式碎核刀,行梯形小切口手法碎核摘除白内障及人工晶状体植入。结果无后囊破裂等严重并发症的262眼(占95.3%)中,术后1周视力≥0.5者207眼(79.0%),术后1个月视力≥0.5者219眼(83.6%),术后1个月视力≥0.3者241眼(92.0%)。术后1周角膜散光平均为(1.50±0.25)D,术后1个月散光为(1.25±0.25)D。结论非超声乳化梯形小切口手法碎核摘除白内障及人工晶状体植入技术是一种可靠的手术方法,且术后反应轻,术中并发症少,挽核容易,切口小,角膜散光小,视力恢复好。
Objective To investigate the effect of trabeculectomy combined with trabeculectomy and cataract extraction and intraocular lens implantation on postoperative corneal astigmatism. Methods A total of 252 eyes (275 eyes) of senile cataract patients were treated with Bailihao style broken nucleus knife, and trapezoidal small incision was used to remove cataract and intraocular lens implantation. Results There were 262 eyes (95.3%) with no severe posterior capsule rupture and 207 eyes (79.0%) with visual acuity ≥ 0.5 at 1 week postoperatively, 219 eyes (83.6%) with visual acuity ≥ 0.5 at 1 month postoperatively, One month after operation, 241 eyes (92.0%) had visual acuity ≥0.3. The mean corneal astigmatism was (1.50 ± 0.25) D at 1 week after operation, and (1.25 ± 0.25) D at 1 month after operation. Conclusion Non-phacoemulsification trapezoidal mini-incision manual shredded cataract extraction and intraocular lens implantation is a reliable surgical method, and the postoperative reaction is light, fewer complications, easy to pull the core, small incision, corneal astigmatism, visual acuity Good recovery.
