Crystalens accommodating intraocular lens account card credit debit updating
With natural, healthy vision, your eye focuses on images near and far by coordinating the curvatures of its outer membrane and inner lens.
The outer membrane is called the cornea, and the inner lens is called the crystalline lens.
Traditional intraocular lenses have a spherical optical design, meaning the front surface is uniformly curved from the center of the lens to its periphery.
Like multifocal IOLs, it is also used for visual correction after the removal of a cataract lens.
The Crystalens accommodating intraocular lens allows for continuous vision up close, far away, and at all distances in between, in most cases with patients experiencing the same vision they had when they were younger, without the inconvenience of corrective lenses.
IOLs also are used for a type of vision correction surgery called refractive lens exchange.
FDA-approved IOLs have been available since the early 1980s.
Until recently, patients undergoing cataract surgery received a monofocal, or single focus intraocular lens (IOL).
Monofocal IOLs implanted in both eyes generally provide excellent distance vision, but patients often need eyeglasses for near and intermediate vision.
