A prototype of a novel dual-mode, accommodating-disaccommodating intraocular lens (AD-IOL) with zonular capture haptics has been fabricated successfully and the lens has shown in bench studies to exhibit axial shift and shape change that results in up to about 26 D of accommodative change, reported Paul M. Beer, MD.
Dr. Beer invented the technology and is founder and CEO of Z Lens LLC, St. Petersburg, FL, the company developing the AD-IOL for commercialization. The AD-IOL is intended for in-the-bag implantation and features a flexible, fluid-filled optic driven by four haptics that are captured by the zonules.
The haptics attach to the anterior portion of the optic–which is the deforming accommodative componentÂÂ–while the posterior portion of the optic, which contains the aphakic prescription, maintains a fixed shape.
“Movement of the crystalline lens is essential for accommodative function,” Dr. Beer explained. “My goal for developing a presbyopia-correcting IOL has been to replicate that movement. Our AD-IOL technology is the only accommodating IOL platform that has been proven to capture the movement.”
