We describe a T-shaped capsule stabilization hook (modified capsule expander [M-CE]) used for repositioning and scleral fixation of the lens capsule of subluxated lenses. The 5-0 polypropylene device is flexible and attached to a curved needle. The contact portion is bent at 1.25 mm, and the end bifurcates in a T configuration to form a 3.75 mm footpad from which the capsular bag can be suspended. Modified capsule expanders were implanted in 4 eyes of 4 patients with subluxated cataractous lenses and provided excellent support and centration of the intraocular lens (IOL)-capsular bag complex. The IOLs remained well centered and stable. The corrected distance visual acuity improved to at least 20/20 in all patients after surgery. Thus, M-CEs were effective in fixating the lens capsule to the sclera in patients with significant zonular weakness.
我们描述了一种 T 形胶囊稳定钩(改良胶囊扩张器 [M-CE]),用于重新定位和巩膜固定半脱位晶状体的晶状体囊。5-0 聚丙烯装置具有柔韧性,并附着在弯曲的针上。接触部分在 1.25 毫米处弯曲,末端呈 T 形分叉,形成一个 3.75 毫米的足垫,晶状体囊可以悬挂在该足垫上。改良胶囊扩张器被植入 4 例半脱位白内障晶状体患者的 4 只眼中,为眼内晶状体(IOL)-晶状体囊复合体提供了极好的支撑和定位。IOL 保持良好的居中且稳定。所有患者术后矫正远视力均至少提高至 20/20。因此,M-CE 可有效将晶状体囊固定于明显悬韧带薄弱的患者的巩膜上。
