We reviewed the records of 20 consecutive eyes with pseudophakic bullous keratopathy associated with a closed-loop anterior chamber lens that underwent penetrating keratoplasty, total anterior vitrectomy, and anterior chamber intraocular lens exchange. On reexamination, all corneal grafts had remained clear during an average follow-up period of 15 months (range, four to 45 months). Seven eyes (35%) attained a visual acuity of 20/40 or better with spectacle correction; however, 15 of 20 eyes (75%) attained a best-corrected visual acuity of 20/40 or better using a pinhole and a gas-permeable contact lens. In five eyes visual acuity was 20/400 or poorer because of cystoid macular edema, as documented by fluorescein angiography, age-related macular degeneration, or optic atrophy. Localized, minimal peripheral anterior synechiae were present on gonioscopy in seven eyes. The one-piece flexible anterior chamber lens implants used for exchange appeared to be well tolerated in this series of patients.
我们回顾了连续20只因闭环前房型人工晶状体导致的假晶状体大泡性角膜病变而接受穿透性角膜移植、完全前段玻璃体切除术和前房型人工晶状体置换术的患眼记录。复查时，在平均15个月（范围4至45个月）的随访期内，所有角膜移植片均保持透明。7只眼（35%）经眼镜矫正后视力达到20/40或更好；然而，20只眼中有15只眼（75%）使用针孔镜和透气性接触镜后最佳矫正视力达到20/40或更好。5只眼因荧光素血管造影显示的黄斑囊样水肿、年龄相关性黄斑变性或视神经萎缩，视力为20/400或更差。前房角镜检查发现7只眼有局限性、轻微的周边前粘连。在这组患者中，用于置换的一体式可弯曲前房型人工晶状体植入物似乎耐受性良好。
