摘要
在4年半内为70只眼后囊不完整者行Ⅰ期后房型人工晶体植入术。术后3个月及1年的随访结果表明,视力达到0.5以上者分别为97.1%和88.6%,并发症相对较少。作者提出后囊膜不完整时Ⅰ期后房型人工晶体植入的原则是:(1)用Healon或空气保持前房深度;(2)人工晶体植入及旋转方向应背向后囊破裂区;(3)人工晶体植入或襻的位置应与后囊破裂部位的子午线相垂直;(4)适当利用残留的前囊代替后囊;(5)尽量清除前房内的玻璃体;(6)至少做两个虹膜周边切除。本手术方法适用于<120°的周边后囊破裂和<4mm的中央后囊破裂。
Abstractprimary implantation of posterior chamberintraocular lens (PC IOL) was perfonned in 70 eyeswith defective posterior capsule followingextracapsular cataract extraction.The visual acuitywas 0.5 or better at 3 months and 12 monthspostoperative in 97.1% and 88.6% of the casesrespectively.Complications were rare.The authors putforth the following principles for such cases:(1)injec-tion of air or Healon to maintain a deep anteriorchamber;(2)the insertion or rotation of the IOLshould be away from the area of capsular rupture;(3)the long axis of the IOL should cross the meridianof the posterior capsule rupture;(4) the residual ante-rior capsule may be utilized to support the IOL;(5)complete clearance of any vitreous in the anteriorchambeber;and(6) performance of at least 2 peripheraliridectomies to guard against pupillary block.Thistechnique is appllcable in eyes with peripheral posteri-or capsule defect of less than 120°or with centralrupture of less than 4mm.
