Repositioning and scleral fixation of subluxated lenses using a T-shaped capsule stabilization hook

Abstract

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.
