人工晶体单襻睫状沟单针双线缝线固定的临床观察

目的观察人工晶体单襻睫状沟单针双线缝线固定植入手术的安全性和有效性。方法对白内障后囊不完整的患者26例（26眼）采用单襻睫状沟单针双线缝线固定法植入后房型人工晶体。术中做以角巩为缘基底的3mm×3mm板层巩膜瓣，使用带两根聚丙烯缝线的长针先作巩膜瓣下缝针用作固定着力点，出针后再从巩膜垂直进针经前房在角膜光学区外3mm出针，剪去长针从白内障切口把聚丙烯缝线夹出，把两根聚丙烯缝线分别结扎人工晶体同一襻，两线结相距3mm，把人工晶体另一襻植入残存后囊上，结扎襻置入虹膜后，同时拉紧巩膜外缝线，调整人工晶体位置使其居中，将巩膜外两根缝线互相结扎，缩瞳，清除干净前房的玻璃体，透明质酸钠，观察术后视力，人工晶体位置，并发症及用药情况。术后随访1～6个月。结果26例（26眼）中术后1周裸眼视力〉10．5者19例（19眼），占73．08％，术后1周裸眼视力0．1～0．4者7例（7眼），占26．92％。人工晶体位置正常24例（24眼），人工晶体位置偏位2例（2眼）。结论人工晶体单襻睫状沟单针双线缝线固定植入手术操作简便，并发症少，安全，效果良好。

Observation on the effect of intraocular lens implantation in single-haptic ciliary sulcus with one needle and double suture fixation

Objective To study the safety and efficacy of intraocular lens implantation in single-haptic ciliary sulcus with one needle and double suture fixation.Methods For 26 patients (26 eyes),the intraocular lens were implanted into single-haptic ciliary sulcus with one needle and double suture fixation.In the operation,the scleral flap was made under corneoscleral limbus( size of 3 mm × 3 mm)and the sutured needle under scleral flap with two polypropylene long suture was as fixation point,then the needle was to be inserted vertically from sclera and with drawn the needle 3 mm from the optical zones of cornea;extracted the polypropylene suture via cataract incision after cutting off long suture and ligated the suture at the same haptics of intraocular lens,the other haptics of intraocular lens was implanted into the residual posterior capsule and made the intraocular lens in the center.The postoperative vision,position of intraocular lens,complications and drug usage were observed,the patients were followed-up from one to six months.Results By one week after operation,the postoperative vision was ≥0.5 in 19 eyes(73.08% ) and between 0.1 and 0.4 in 7 eyes(26.92% ).the position of intraocular lens was normal in 24 cases(24 eyes)and lens decentration in 2 cases(2 eyes).Conclusion The intraocular lens implantation in single-haptic ciliary sulcus with one needle and double suture fixation is simple,safety and less complication,and the effect is good.
