It incorporates liquid crystal chemistry, electricity and integrated circuity to provide clear, accommodating vision.
What this means is that the Sapphire IOL actually runs off a battery (which has an expected lifespan of 50 years).
The electrical current adjusts the lens focusing power based not only on distance, but also on other factors like work and light environment.
One major difference of this battery-powered approach is that it’s not reliant on ciliary muscle function to control vision accommodation.
Most monofocal IOL patients opt for distance vision, then use eyeglasses for near vision.
The second, fluid-based lens, which provides a more full range of focusing power, is then implanted through a smaller incision made possible by the base lens. Eric Donnenfeld believes that the Juvene lens “is the most exciting [lens] for the short-term treatment of presbyopia.” To learn more about the Juvene accommodating IOL, check out Developed by Elenza, the Sapphire Auto Focal IOL sounds quite futuristic.
As the muscles within the eye contract and relax, the tiny amount of fluid in the lens moves to maintain visual acuity.
Power Vision claims that clinical results have confirmed the Fluid Vision lens offers 3 to 4 diopters of accommodative power.
An ambitious IOL indeed, but probably one that’s quite a few years from becoming a viable alternative.

And considering that everyone over the age of 50 eventually develops presbyopia, it’s no wonder why so many companies are investing in the development of accommodating IOLs.
