Tetraflex accommodating

THE STALLED Sapphire Autofocal (Elenza, Inc.) is billed as the first “electro-active” accommodating IOL.Accommodation occurs by means of a liquid crystal optic that changes power in response to an electronic signal.Bausch Lomb acquired Crystalens in early 2008; and in June of that year, the FDA approved a “high-definition” version of Crystalens, which incorporates an optic designed for better near vision.

IOL developers continue to investigate new accommodating designs in hopes of gaining enough accommodation to provide sharp vision at all distances.When Abbott Medical Optics (AMO) acquired Visogen for 0 million in 2009, Synchrony had just received CE marking in Europe.However, the lens got stalled in the FDA approval process for three years, and eventually AMO discontinued it.This design strategy trades off some of the benefits of seeing through a single zone in order to have a greater range of focus. While many multifocal patients can read without glasses, their distance vision may not be as sharp as it might be with a monofocal IOL.Multifocal patients often complain of seeing glare and halos, especially at night, in the first few months after surgery.
