Unmet Need
Cataract surgery is the most common intraocular surgery, with more than 3.5 million occurring each year in the U.S. Various circumstances compromise the ability to safely insert an intraocular lens (IOL) implant following cataract extraction such as zonular insufficiency or posterior capsule rupture. Alternatives for IOL placement within the native lens capsule or ciliary sulcus (such as anterior chamber IOLs, iris-fixated lenses, or scleral-fixated lenses) have been described. These alternate methods require specialized adjustments in IOL design or surgical techniques that generally are cumbersome, require high skill level, and are associated with a range of intra- and post-operative complications.
Technology Overview
The inventors have developed a synthetic lens capsule that can be used for IOL implantation in the absence of capsular support without requiring modification of the IOL. This device can be placed through a standard incision for cataract surgery. The capsule material is compatible with existing techniques for treatment in the event that the capsule loses clarity after implantation and the device can be removed from the eye using a small incision if needed. The device provides an opportunity to simplify visual rehabilitation in cases of inadequate capsular support for IOL fixation.
