It's also important for accommodating IOL candidates to have realistic expectations about the outcome of their surgery.

Accommodating IOLs cannot restore a person's near vision to the same level it was prior to the development of presbyopia, and other age-related changes in the eye may continue to affect visual acuity after surgery.

Because the central optical portion of an accommodating IOLs typically is less flexible than the eye's natural lens, these intraocular lenses must work in a different way.

Instead of changing shape, an accommodative IOL moves slightly forward within the eye in response to focusing effort.

In some cases, an accommodating IOL may be properly implanted, but the ciliary muscle or the zonules attaching the lens capsule to the muscle may no longer function properly.

Another option is a non-laser procedure called limbal relaxing incisions.Candidacy for accommodating IOL surgery is determined using the same criteria used to determine candidacy for either refractive cataract surgery or refractive lens exchange.Candidates also must understand and be willing to accept the potential risks and complications associated with accommodating IOL surgery.When the ciliary muscle contracts, this action loosens the zonules connecting the muscle to the lens capsule.It also increases pressure exerted by the vitreous body — the clear, gel-like material filling the back of the eyeball, behind the lens capsule.
