Accomodating and problems with radiometric dating of rocks
Accommodation is made possible by the lens inside the eye and the circular muscle that surrounds the lens, called the ciliary muscle.
The lens and ciliary muscle are connected by a 360-degree series of fibers (called ciliary zonules) that extend from the ciliary muscle to the thin lens capsule (or "bag") that encloses the lens.
This is why they are classified as "accommodating IOLs." Both lenses are manufactured and distributed by Bausch Lomb.
In a normal eye (without presbyopia or cataracts), this dynamic process of accommodation adjusts the focusing power of the eye by changing the thickness of the eye's natural lens.
It is certainly reasonable to use this strategy when the issue at hand is something of little importance to you.
If you are trying to pick a movie to watch, and you really don't care, it's fine to say 'Whatever you want is ok with me'.
During cataract surgery, a circular opening is cut in the anterior part of the lens capsule so the surgeon can remove the eye's natural lens that has become cloudy. The peripheral and posterior portions of the lens capsule are left intact, forming a partially open "bag" that the intraocular lens is positioned within to restore focusing power to the eye.
All IOLs have a central optical zone, with peripheral "legs" (called haptics) that secure the lens implant inside the lens capsule.
They are noisy, vicious, unaccommodating and aggravating to a degree.
