The Problem: Loss of Accommodation
Accommodation is the ability to adjust your eyes to see near, far or anywhere in between. The natural human lens does this by changing shape, getting thinner (disaccommodated, for distance vision) or thicker (accommodated, for near vision).
As we age, the eye naturally loses its ability to accommodate and seeing objects clearly at near becomes more difficult. This process happens continuously but is particularly noticeable through age 40 to 50 when typical near vision tasks, such as reading, become a challenge. This vision condition is also known as Presbyopia and occurs in virtually everyone. However, as we get older, we can also develop a cataract which causes the normally clear natural lens in the eye to turn opaque or cloudy. Patients with cataracts have their natural lens removed and replaced with an artificial lens, called intraocular lens (IOL). While this artificial lens usually allows the patient to regain clear vision, it cannot mimic the eye’s natural accommodative process of dynamically adjusting focus at all distances. The FluidVisionTM IOL is designed to give the patients freedom from ever needing glasses, contact lenses or any vision correction procedure again.
