摘　　要：目的　探讨 3 5mm角膜缘隧道切口囊袋内手法碎核白内障摘除人工晶体植入术的临床效果。方法　在上方角膜缘做 3 5mm隧道切口 ,采用晶状体囊袋内手法碎核技术对 12 8只眼行白内障摘除 ,并植入折叠式或PMMA人工晶体。结果　 12 8只眼中 ,12 0只眼成功完成囊袋内碎核 ,未成功者与浅前房、小瞳孔及水分离不充分有关。术后 1天裸眼或球镜矫正视力≥ 0 6者占 79 7% ,术后 1周平均散光为 ( 0 95± 0 74)D ,仅比术前增加 0 0 8D (P >0 0 5 ) ,明显低于 12mm切口囊外摘除组 (P <0 0 1)。结论　本结果提示 3 5mm角膜缘隧道小切口囊袋内手法碎核白内障摘除和人工晶体植入技术 ,可有效减少术后角膜散光并早期获得良好视力 ,降低手术费用。Objective The study was designed to investigate the clinical effects of extracapsular cataract extraction(ECCE)with intraocular lens implantation by manual fragmentation lens nucleus in capsule and through a 3.5mm limbus tunnel incision.Methods The surgery using manual fragmentation nucleus technique in capsule with foldable intraocular lens implantation or PMMA IOL was performed through a 3.5mm limbus tunnel incision on 128 eyes.Results Manual fragmentation nucleus technique in capsule was successfully completed in 120 of 128 eyes(93.8%),unsuccessful cases were related to shallow anterior chamber、small pupil and incomplete hydrodissection.Postoperatively,the visual acuities with spherical correction or without correction were 0.6 or better in 79.7% of the eyes at one day.The mean postoperative astigmatism was(0.95±0.74)D at one week,only 0.08 more then the mean preoperative astigmatism one(P>0.05)and significantly less than ECCE group with 12mm incision(P<0.01).Conclusions These results suggest that extracapsular cataract extraction(ECCE)by manual fragmentation lens nucleus in capsule through a 3.5mm limbus tunnel incision not only can reduce postoperative corneal astigmatism and provided a satisfactory vision in postoperative early stage,but also can decrease the expenses of the operation.
