The lens is suspended by a ring of fibres about 1-2μm thick from the ciliar muscle. Getting accommodation to work with a synthetic lens would require a substitute suspension mechanism to attach the lens to the muscle. And it would probably be useful if it could be implanted without temporarily removing the front or the eye including the iris.

Compare that to a small cut to the side of the eye to extract the old lens and inject a new one that is held in place mechanically.
