摘要
目的探讨改良的小切口非超声乳化人工晶状体植入术的安全性和疗效。方法回顾性分析2000年至2005年在我院行改良的小切口非超声乳化人工晶状体植入术的白内障患者32例(38眼)。手术中隧道切口较长(内切口与外口之间距离3～4mm)。植入光学部直径为6.0mm的PMMA一体型人工晶状体,通过被植入人工晶状体,利用C襻驱使切口12:00点处皮质进入瞳孔区和前房后吸出。术后随访1～2a。结果术后1周内裸眼视力达到0.5以上者30眼,术后1～2个月裸眼视力达到0.5以上者32眼,1a后仍保持0.5以上者30眼。术后1周、1～2个月、1a角膜散光分别为(1.15±0.56)D、(1.05±0.46)D、(0.76±0.23)D,与术前(0.56±0.28)D相比差异均无统计学意义(P>0.05)。术后无渗漏,前房形成良好,眼压均在正常范围内波动。术后2a5眼出现晶状体后囊点状混浊。结论改良小切口非超声乳化人工晶状体植入术治疗白内障,免缝线,手术安全性高,效果良好,操作简便,适合基层医院推广。
Objective To investigate the safety and effect of reformed intraocular lens implantation with non-phacoemulsification through small incision.Methods Retrospective study was taken at 32 patients（38 eyes） who were performed reformed intraocular lens implantation with non-phacoemulsification through small incision in our hospital between the year 2000 and 2005.The tunnel was much longer in the operation,and the space between inner incision and outer incision was 3 mm to 4 mm.PMMA lens with diameter of 6.0 mm were implanted in the operation.Through the C haptics of the lens the cortex in 12 o＇clock was drived into the areas of pupil and anterior chamber and then to be drawn-off.All patients were followed-up for 1 to 2 years after the operation.Results The naked visual acuity better than 0.5 was 30 eyes at 1 week after operation,32 eyes during 1 to 2 months,and 30 eyes remained for 1 year.The corneal astigmatism at 1 week,1 to 2 months and 1 year postoperatively were（1.15±0.56）D,（1.05±0.46）D and（0.76±0.23）D,respectively.There was no statistically significant difference compared with preoperative（0.56±0.28）D（P〉0.05）.No leakage was found in all eyes.The anterior chambers were all formed well,and the intraocular tension was fluctuated in normal ranger.Posterior capsule opacification happened in 5 eyes at 2 years postoperatively.Conclusion Reformed intraocular lens implantation with non-phacoemulsification through small incision for cataract does not need suture,and the operation is safe,effective,and simple.It can be applied to extensive basic hospital.
