Clinical trials have been completed in Europe, and Akkolens is anticipating a CE mark. Expanding PC-IOL Options Expected to Fuel Demand Among Patients.
Swiss Advanced Vision, a company that designs, manufactures, and distributes a new generation of intraocular lenses for cataract surgery, recently announced a new product for post-cataract surgery, an intraocular lens (IOL) called In Fo Instant Focus, that is says restores “perfect vision.” The In Fo lens is the first implant that offers unmatched quality of vision at all distances after removal of the crystalline lens in patients going through cataract surgery, the company says in a press release.
(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.
A drawback to most mechanical accommodating IOLs is that the ciliary muscle may not be strong enough to power the lens to provide an in-focus image at every distance.
As a result, currently approved accommodating lenses typically can’t provide a full range of vision.
As a result, considerable time and money are being invested in the development of IOLs that reduce or eliminate the problems of current multifocals.After two years of development in 2010, Elenza approached Alcon for financing.Over the next 11 months, Alcon conducted a due-diligence review and made a first-round investment of several million dollars.Accommodating IOLs One approach, accommodating IOLs, tackle the problem differently.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.
