Multifocal intraocular lenses (IOLs) are the most striking advance in cataract and presbyopia corrective surgery
in 25 years. Traditionally, artificial intraocular lens implants were monovision, meaning that they could only focus
distance, near or intermediate between the two. However, in most cases, reading glasses or bifocals were still needed
to permit fine visual tasks such as small print. Now multifocal intraocular lenses, also known as
bifocal IOLs, can eliminate the need for glasses in most patients. Studies have shown that these lenses can help
you regain natural youthful vision, allowing you to drive, read, enjoy sports, and work on the computer with little or
no need for glasses. At EyeCare Associates of San Francisco we offer our patients the choice between two industry
leaders in multifocal IOLs, the Alcon ReSTOR® lens and the AMO Tecnis® Multifocal lens.
Multifocal IOL Implants for Presbyopia Correction
As our eyes age, the ability of the natural lens to “accommodate” (focus at various distances) diminishes,
generally noticeable around age forty. This is called presbyopia and reading glasses or bifocals are often needed.
Multifocal intraocular lens implants allow presbyopia patients to become glasses-free once again by replacing the
eye’s natural lens with an artificial lens capable of focusing far and near distances. For this reason multifocal
intraocular lenses are often called presbyopia-correcting IOLs.
Multifocal IOL Implants for Cataract Surgery
Aging can also cause the eye’s natural lens to become more opaque, creating a cataract which results in cloudy vision.
Cataracts can only be fixed by surgery to replace the natural lens with an artificial lens inside the eye. Now patients
undergoing cataract surgery can opt for a high-tech multifocal intraocular lens, which has the ability to correct vision for distance and near thus minimizing the need for glasses.
Alcon ReSTOR® Intraocular Lens Implant
The ReSTOR® intraocular lens is unique in that it works by combining the strengths of diffractive and refractive
technologies. It is the only IOL to utilize apodization, the gradual bending and reduction of the diffractive step
heights, to create a smooth transition between distance, intermediate and near focuses. In clinical studies, four out
of five patients reported never needing to wear glasses again, compared with one in ten patients who received monovision
AMO Tecnis Mutifocal Intraocular Lens Implant
The AMO Tecnis Multifocal Intraocular Lens Implant offers another option for the correction of presbyopia. This lens uses
diffractive optics, which are independent of pupil size. It also significantly reduces optical abnormalities known as
spherical aberration and chromatic aberration. The design of this lens results in sharp vision for distance and near
independent of lighting conditions. Approximately 90% of patients with this lens implant function comfortably without
glasses for all distances: near, intermediate and far.
EyeCare Associates of San Francisco is pleased to offer the latest multifocal lens implants for our patients who wish
to restore natural youthful vision after lens surgery. Your surgeon will choose the lens which is best for you. All operations have risks and multifocal implant surgery is no exception. There is a small level of risk involved in
implanting these lenses. For a complete discussion of the benefits and risks of these lenses, please contact us today to schedule an appointment with one
of our surgeons. We are a Medicare participating provider and a preferred provider of most major medical service and
vision insurance plans. Your intraocular lens implant surgery may be covered in part or in whole by Medicare or your
insurance provider. Please email or call if you wish to inquire about insurance
plans or have any other questions regarding multifocal intraocular lens implants in the San Francisco Bay Area.
