In-the-bag injection and overfold technique for custom flexible prosthetic iris prostheses

Abstract

In-the-bag placement is the ideal location for an anterior segment implant, including the custom flexible artificial iris prosthesis (CUSTOMFLEX ARTIFICIALIRIS). Yet, an injection of a bag-filling iris device through a reasonably sized capsulorhexis creates a geometric challenge. First, the device must be placed into an injection cartridge. Folding into a conoid, trifold orientation improves the facility with which the device is loaded into the injector barrel. To facilitate placement into the capsular bag, the device that is approximately 10+ mm is injected into the nasal bag, and the temporal portion is overfolded on itself to reduce its outer diameter.
