Dual optic accommodating
In this study, the near visual performance provided by the Synchrony AIOL was evaluated over a 4 yr time period after cataract surgery.
METHODS: Fourteen patients (28 eyes) with bilateral Synchrony AIOL implantation were prospectively enrolled 4 years after cataract surgery.
Instead of placing multiple focusing elements in a single fixed lens, most accommodating lenses change focus by utilizing a single optical element that moves like a camera lens or alters shape.
PURPOSE: Accommodating Intraocular lenses (AIOLs) are designed to dynamically respond to ciliary muscle forces to restore accommodation in a pseudophakic eye and improve vision at all distances from far to near.
Recently, novel AIOLs have been developed and demonstrated to provide improved near vision.
It is of interest to evaluate performance of such lenses over long periods of time to understand their sustained clinical utility.
(Eyeonics, Inc., Aliso Viejo, Calif.) is the only Food and Drug Administration-approved accommodating intraocular lens.
forecasts nearly 11% growth in presbyopia-correcting IOLs through the end of 2016 as new options become available. Presbyopia correction can be approached in a number of ways.
Multifocal IOLs incorporate discrete optical elements into the lens to offer both near and distance vision.
There will always be halos or ghost images produced by the secondary focal zone.
Finally, a multifocal lens cannot provide excellent vision across the entire range of intermediate to near zones.
