Accomodating intraocular updating tongue and groove oak panel
AO IOL delivers an active range of vision, excellent contrast sensitivity, and minimized issues with halos and glare across a range of vision that includes functional near, intermediate, and distance vision.
posterior accommodating intraocular lens (IOL) is intended for primary implantation in the capsular bag of the eye for the visual correction of aphakia secondary to the removal of a cataractous lens in adult patients with and without presbyopia.
Here we present a novel accommodating intraocular lens (AIOL) able to reshape upon equatorial forces in compliance with the eye’s accommodating mechanism.
The concept and design parameters are demonstrated through finite element model simulations and measurements in a manufactured AIOL prototype, using custom quantitative 3D OCT (geometrical changes) and laser ray tracing (power changes), with forces radially applied using a custom eight-arm mechanical stretcher.
Federal (USA) law restricts this device to the sale by or on the order of a physician.Do not store lenses at temperatures over 45°C (113°F).Careful preoperative evaluation and sound clinical judgment should be used by the surgeon to decide the benefit/risk ratio before implanting a lens in a patient with conditions as outlined in the AO IOL Directions for Use.

Presbyopia, the age-related loss of the crystalline lens’s ability to dynamically focus, occurs primarily because of stiffening of lens material, making the ciliary muscle forces insufficient to reshape the lens.
