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

摘要

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. Financial Disclosure Dr. Tassignon has a proprietary interest with Morcher GmbH for both the bag-in-the-lens implant and the bean-shaped capsular tension ring segments. Dr. Ní Dhubhghaill has no financial or proprietary interest in any material or method mentioned.
