As a result, currently approved accommodating lenses typically can’t provide a full range of 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.

(Very similar in design, the FDA allows Crystalens to be called “accommodating” but only allows Trulign to be described as offering “a broader range of vision.”) Both are mechanical IOLs because accommodation is powered by action of the ciliary muscle as opposed to, for example, electricity.

The lens contains a rechargeable battery and changes focus based on physiological triggers.

After two years of development in 2010, Elenza approached Alcon for financing.

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.

In 2010, Bausch Lomb introduced the Crystalens Aspheric, which has an optical design that gives it improved contrast sensitivity and reduces higher order aberrations.

Instead of placing multiple focusing elements in a single fixed lens, most accommodating lenses change focus by utilizing a single optical element that moves like a camera lens or alters shape.
