人工晶体植入术在复杂性眼外伤中的应用(附一例报告)
人工晶体,现报告如下病例介绍患者.刘x,男,勰岁。住院号}21I9】6。1991年10月园左眼球贯通伤由当地医院作角膜缝合及眶内异物取出术。术后第5又行外伤性自内障摘除术。1月后四玻璃体积啦在我豌行玻璃体切除术。术后2周见玻璃体内膜样增殖和继发性视网膜脱离第4次旅行玻璃体切除加巩膜环扎术术后矫正视力0.2,半年时为1.0,[link widoczny dla zalogowanych]。患者迫叨要求植人工晶体于次年5月再次院,[link widoczny dla zalogowanych]。检查发现左限角膜颞象限浑浊.相应墨虹膜前粘,[link widoczny dla zalogowanych],部份虹膜缺损致瞳孔呈大。c形.晶体缺如且无后囊,玻璃体混浊,余正常。右眼视力I.5。综台分析病情决定二=期植人工晶体井作缝线固定术,人工晶体光学区直径7mm,}2ID.局麻下手术.切开球结膜,在l2~3点位距角膜缘1.5mm处作板层巩膜瓣8点位作三角形巩膜瓣:用4.5号注射针头由2点位瓣下朝人球内,经虹膜后达8点位时穿出球壁,针刺点距角膜缘Imrtl,贯通睫状沟,[link widoczny dla zalogowanych];借针尖孔引人7--~0聚丙烯缝线,原路退针时线贝n穿于球内。在l2~3点住巩膜板’F全层切开角膜.向前房注粘祷剂,期镊子夹出瞳孔区聚丙烯线,中问藏断后分别缚在人工晶体2襻上,襻端制成蘑菇头状;送晶体达虹膜后,抽紧球外固定线并埋于巩腰瓣下调整晶体位置,冲洗粘稠帮、常规缝台切口,结膜下注药。术后垒身用皮质类固醇及抗生索。随访3个月时视力0.5,10个丹为1O讨论以往认为复杂性眼外伤的视功能难有很好恢复,也有人指出无晶体后囊者不窘植人人l』:晶体近年束由于显撤外科迅速发展,一期人工晶体植人手术获得了可喜的疗效。国内外陆续报告二期植人时可将体襻悬吊式固定在睫状淘中“,为复杂性眼外伤的治疗开辟了新路。本文患者左眼矫正视力I0是决定二期植人:[晶体的重要指征,[link widoczny dla zalogowanych],粘连性角膜白斑尚不影响晶体人路.虹膜缺损及晶体后囊缺如必然影响人工晶体的稳定性,故决定用聚丙烯线加圈晶体襻,线端结扎在巩膜瓣下,手术略显复杂但效果十分理想该饲手术的成功使我们体会到在复杂性跟外伤的治疗及时细致的修复刨伤是抢救的关键,:=期植人人工晶体对,加用球甜圊定线是预防晶体倾斜、移位的重要环节。
