Bean-shaped ring segments for capsule stretching and centration of bag-in-the-lens cataract surgery

J Cataract Refract Surg. 2014 Jan;40(1):8-12. doi: 10.1016/j.jcrs.2013.11.023.

Abstract

The bag-in-the-lens (BIL) is a unique approach to IOL placement in cataract surgery. The BIL intraocular lens (IOL) is suspended centrally, supported by the anterior and posterior capsulorhexes. The placement confers a high degree of centration and stability; however, it is dependent on capsular and zonular integrity. In this report, we describe a patient with posttraumatic cataract featuring a sector of iris and suspensory zonule loss. The insertion of custom-designed bean-shaped segments provides capsular tension over the area of defect and a central aperture designed to support the BIL IOL.
