A dual optic accommodating lens is a new lens design for cataract surgery patients that incorporates two optics, typically connected by a bendable material. Of the various accommodating IOL designs, and there are many, a dual optic lens would seek to mimic the natural accommodation of the eye.

Accommodation is the eye’s ability to shift the lens to be able to see at multiple distances. In the past, cataract surgery lenses were a single optic with only one available distance for viewing (monofocal lens). Another type of lens seeks to eliminate the need for glasses presented by monofocal lenses. Multifocal lenses have one optic, but multiple viewing areas. This allows for viewing at multiple distances, sometimes without glasses.

The most recent additions to the cataract lens options are accommodating lenses. These will soon be offered in both single and dual optic designs. These lenses typically shift or adjust to mimic the natural accommodation of the original lens. This is accomplished in various ways, but the most common way is to shift the lens using the muscles of they eye.

Dual optic accommodating lenses will present a new option for cataract patients looking to avoid glasses after surgery. Like with any lens, promises are hard to come by. Every patient is different, and it is currently unrealistic to expect 100% glasses independence. Some of the new lenses may come close, but none guarantee it. Patients should be very aware of this before spending the extra money for theses lenses in the hopes of total glasses independence. The cost for these lenses is usually out of pocket.
