In 2010, Bausch Lomb introduced the Crystalens Aspheric, which has an optical design that gives it improved contrast sensitivity and reduces higher order aberrations.
In May 2013, the FDA approved a toric version of the lens, called Trulign.
(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.
In clinical studies, Crystalens and Trulign have been shown to provide about 1 diopter of accommodation.
Typically, the eye’s “focusing” or ciliary muscle powers the movement or shape change.
As a result, currently approved accommodating lenses typically can’t provide a full range of vision.
Clinical trials have been completed in Europe, and Akkolens is anticipating a CE mark. Expanding PC-IOL Options Expected to Fuel Demand Among Patients.
