To review the visual and surgical outcome of planned intracapsular cataract extraction (ICCE) and anterior chamber intraocular lens (AC IOL) implantation for subluxated crystalline lenses.
Eight eyes of 7 patients with subluxated lenses which underwent planned ICCE, AC IOL implantation and peripheral iridectomy by one surgeon between September 1995 and November 1996 were prospectively followed-up to ascertain their visual and surgical outcome.
There were 4 male and 3 female patients. Their mean age was 64.4 years (range, 39-86 years). Seven lenses were removed by cryoextraction while one was removed with the aid of a vectis. The mean post-operative follow-up was 11.6 months, (range, 3-22 months). Excluding 1 eye with pre-existing ocular pathology, all eyes achieved a best corrected visual acuity (BCVA) of 6/12 or better post-operatively. One of these eyes, in a schizophrenia patient, developed subluxation of the AC IOL and retinal detachment 11 months after the cataract surgery due to repeated eye rubbing. The final BCVA became 6/120 after successful repositioning of the AC IOL and retinal re-attachment surgery. One eye achieved a BCVA of 6/36 due to age-related macular degeneration.
Our results show that planned ICCE and AC IOL implantation is a useful and safe procedure in the management of subluxated lenses.
回顾计划性囊内白内障摘除术（ICCE）联合前房型人工晶状体（AC IOL）植入治疗晶状体半脱位的视觉和手术效果。
对1995年9月至1996年11月间由同一位外科医生进行计划性ICCE、AC IOL植入及周边虹膜切除术的7例晶状体半脱位患者的8只眼进行前瞻性随访，以确定其视觉和手术效果。
男性4例，女性3例。平均年龄64.4岁（范围39 - 86岁）。7只晶状体通过冷冻摘除，1只借助晶状体钩摘除。术后平均随访11.6个月（范围3 - 22个月）。排除1只术前存在眼部病变的眼睛，所有眼睛术后最佳矫正视力（BCVA）均达到6/12或更好。其中1只眼的患者为精神分裂症患者，白内障手术后11个月因反复揉眼导致AC IOL半脱位和视网膜脱离。在成功复位AC IOL及视网膜复位手术后，最终BCVA变为6/120。1只眼因年龄相关性黄斑变性，BCVA为6/36。
我们的结果表明，计划性ICCE联合AC IOL植入是治疗晶状体半脱位的一种有效且安全的方法。
