How to be more accommodating
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.
And, as time goes on, other highly novel lens accommodation strategies will be developed.
With these new IOLs, as the ciliary muscle contracts, the accommodative lens contracts with it, curving and thickening to allow for focusing up close. Essentially, an accommodative IOL is the closest thing to the natural lens of the eye.
The only accommodating IOL currently approved by the FDA is Bausch Lomb’s Crystalens.
A contracted ciliary muscle increases the focusing power of the lens by increasing the lens curvature, catering to near vision.
A relaxed ciliary muscle allows the lens to flatten for clear distance vision.
Conversely, accommodating monetary regimes are compatible with real wage restraint and full employment in centralized bargaining systems, while they encourage wage-price militancy in decentralized ones.
Their six guiding principles for research capacity building include a whole system approach, accommodating diversity, reducing barriers to participation, enabling collaboration, mentoring and networking.
What this means is that the Sapphire IOL actually runs off a battery (which has an expected lifespan of 50 years).
However it does not correct for medium vision between the two and can sometimes leave the quality of vision, as measured by contrast sensitivity, lower than experienced with glasses across all distances.
Which brings us to accommodating IOLs, the Rolls Royce of implantable lenses.
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.
