Cataract Surgery Intraocular Lens (IOLs) Options
If you are considering cataract eye in Orange County, CA, the next step is to schedule a consult and meet Dr. Chao to have your eyes examined and discuss how you'd like to see the world after vision correction surgery.
You'll learn about the different intraocular lens (IOLs) options for implantation after cataract removal. At Chao Vision Institute, you'll have the best of monofocals and custom IOLs to choose according to what best fits your lifestyle.
As a cataract, LASIK and corneal refractive eye center, we are able to provide comprehensive specialty vision care along with comfort and convenience at Chao Vision Institute in Irvine, CA.
Why Choose a Custom IOLs?
The first IOLs were developed in the late 1940's and have become an essential part of routine cataract surgery. Most IOLs are made of flexible materials which allow for them to be folded and injected into the eye through a very small incision. The IOL is intended to last a lifetime. The perfect intraocular lens has not yet been created but advances in technologies offer patients what previous generations of lenses could not have achieved.
While monofocal intraocular lenses (IOLs) offer a single vision option (e.g. distance vision), Custom IOLs, including accommodative IOLs (e.g. Crystalens lenses) and multifocal IOLs (e.g. ReStor, ReZoom) can lessen your dependence on glasses or contacts by offering fuller range vision (e.g. computer vision or reading vision in addition to distance vision). Toric IOLs (e.g. Acrysof Toric) can correct for astigmatism as well as provide for distance vision.
Accommodative IOL | Presbyopia Correcting
Accommodative lenses (e.g. Crystalens IOLs) are designed to bend or "flex" in the eye to mimic a focusing action of the human eye. These lenses can reduce or possibly eliminate your dependence on reading glasses, but as with all lenses, limitations do exist.
Crystalens™ Lenses
Crystalens™ lenses (B&L) are FDA-approved accommodative intraocular lenses, providing excellent distance vision as well as excellent intermediate vision in most cases. The newest version of accommodating lens designed to further improve near vision, Crystalens HD, is the fourth generation of accommodating lens.
The surface of the Crystalens HD has been shaped to enhance the depth of focus with a proprietary optical modification. The enhanced optic provides an increased depth of focus which is designed to improve near vision without compromising intermediate or distance vision. The HD lens does this without inducing increased undesirable dysphotopsia or night vision symptoms.
Multifocal IOLs | Presbyopia Correction
Two FDA approved multifocal lenses are currently in popular use today as a replacement lens after cataract surgery. These can reduce or possibly eliminate your dependence on reading glasses, but as with all lenses, limitations do exist. Slightly more glare and halos at night are amongst the side effects; although these do diminish over time.
Acrysof ReStoR™
The ReStoR IOL (Alcon Surgical) has a unique design in providing near vision by utilizing different zones on the lens itself. The technology is called apodized diffractive optics and serves to provide great distance and near vision.
An aspheric version of this lens has been FDA-approved, providing solutions to help offset aberrations or distortions in the eye that can cause vision problems such as reduced night vision and contrast sensitivity.
Toric IOL | Astigmatism Correcting
Acrysof Toric™
Astigmatism is most often caused by the cornea being football-shaped, causing blurring of vision at all distances. Toric lenses are designed to correct for astigmatism. Currently, these lenses are only able to provide clear distance vision and are not able to provide near vision without the use of glasses or contacts. The AcrySof Toric IOL (Alcon Surgical) has a unique design making it possible to reduce or eliminate corneal astigmatism and significantly improve uncorrected distance vision.
Distance-Correcting IOL | Monofocal IOL
Akreos AO™
Cataract surgery with monofocal IOL implantation provides excellent distance vision, but readers or computer glasses are needed for reading or near vision and computer or intermediate vision.
The Bausch and Lomb Akreos AO™ is an advanced acrylic foldable monofocal IOL with a unique four arm haptic deign to optimize centration in the eye. With an aspheric design, it greatly diminishes abberations to give optimized distance vision correction.
