半囊袋内手法碎核在小切口白内障摘除术中的应用效果观察

Manual half-intracapsula chop technique in small incision non-phacoe mulsification cataract surgery

目的:探讨半囊袋内手法碎核技术在小切口白内障囊外摘除术中的应用效果。方法:对晶体核硬度在Ⅲ级以上的白内障患者26例(27眼)行常规小切口手术,环形撕囊,采取半囊袋内手法碎核,将核碎为2～3瓣,逐一取出。囊袋内植入人工晶体。结果:27眼均顺利碎核,无后囊破裂发生;术后7眼出现上方角膜轻度水肿;2眼出现角膜中上方内皮轻度块状混浊,分别为Ⅳ级和V级核。术后第1天,视力≥0.5者20眼,其中≥0.8者8眼;术后7天,视力≥0.5者23眼,其中≥0.8者10眼。结论:半囊袋内手法碎核技术增加了前房操作的空间,减少了对角膜内皮细胞的损伤,操作安全,值得推广应用。

Objective：To evaluate the clinical effect of manual half-intracapsula chop technique in small incision non-phacoe mulsification cataract surgery（SICS）.Methods：Twenty-six cases（27 eyes）of cataract with above grade-Ⅲ nucleus were performed conventional small incision cataract surgery using manual half-intracapsula chop technique.Each nucleus was separated into two or three pieces which were taken out one by one;intraocular lens was implanted in each eye.Results：The necli were successfully separated in 27 eyes with no posterior capsular rupture.After the operation,slight cornea edema was observed in 7 eyes and slight massive opacity of the endothelium in 2 cases.The visual acuity of 20 eyes was improved to 0.5 or over one day after the operation,among which more than 8 eyes reached 0.8.The visual acuity of 23 eyes was improved to 0.5 or over one week after the operation,among which 10 eyes or over reached 0.8.Conclusions：Manual half-intracapsula chop technique can expand the operation space and reduce the lesion to coneal endothelium.It is a safe method for treatment of patients with cataract.
