摘　　要：目的　探讨 5 .5～ 7mm角膜缘有缝线切口与 10～ 12mm传统角膜缘阶梯大切口行白内障摘除人工晶体植入术的疗效。方法　在角膜缘作 5 .5～ 7mm隧道切口 ,水分离 ,娩出晶体核 ,或角膜缘阶梯状 10～ 12mm大切口娩核 ,并植入PMMA人工晶体。结果　小切口较大切口术后第 1天裸眼或球镜矫正视力、术后半月平均散光均有明显优势。结论　 5 .5～ 7mm角膜缘有缝线切口白内障摘除人工晶体植入术 ,优越于传统角膜缘阶梯状大切口白内障人工晶体植入术 ,可有效减少术后角膜散光并早期获得良好视力。Objective The study was designed to investigate the clinical effects of extra capsular cataract extraction (ECCE) with a 5.5～7 mm limbus tunnel incision with suture or a 10～12 mm traditional ladder limbus big incision.Methods The surgery was performed by employing hydro-dissection and parturition nucleus through a 5.5～7 mm limbus tunnel incision with suture or a 10～12 mm limbus big incision and implant PMMA IOL. Results The small incision was superior to big incision on the visual acuities with spherical correction or without correction of the eyes in the following day and the mean postoperative astigmatism for the following weeks.Conclusion These results suggest that extra capsular cataract extraction by 5.5～7 mm limbus tunnel with suture is superior to the traditional ladder big incision not only reducing postoperative corneal astigmatism but also providing a satisfactory vision in postoperative early stage.
