Bifocal Lens Implants

Multi-Focal IOL Implants also known as Bifocal Lens Implants
Marietta Eye Clinic - Georgia’s Premium Source For Quality Cataract Care

“Advanced IOL technology comes to Marietta Eye Clinic and with it the promise of major improvements in vision after cataract surgery”.

If you are a patient that is considering cataract surgery we are happy to announce the arrival of bifocal lens implants that can help you see better after cataract surgery. Previously, cataract surgery patients had only one choice for a new lens implant after surgery and it was with a monofocal lens implant. Monofocal lens implants only provide vision at one distance, which is typically for long distances. In this case, patients will require glasses for reading or other near vision activities. Now that modern medical technology has brought us bifocal lens implants, our patients now have the ability to see without glasses at multiple focal points after cataract surgery. There are various types of bifocal lens implants that the doctors at Marietta Eye Clinic use. It is important to note that although there are various options the doctors here are professionals at determining the best lens for you based on your individual visual situation. We always strive to help you achieve your personal best vision.

Accommodating IOL

The process of an eye focusing from distance to near is known as accomodation. Accomodating lens implants are an alternative to traditional lens implants that give patients back an increased range of vision.  These special lenses are modeled after the human eye to mimic the way an eye's natural lens would see. An accomodating lens changes focus from a distance to a near range, much like our eyes when we are younger.  The only accomodating lens available is the Crystalens by Bausch & Lomb.

What is the Crystalens ©?

The Crystalens is an itnraocular lens that has been FDA approved since 2003.  It is used for visual correction of adults with cataracts.  The Crystalens acts like the natural lens, using the eye muscles to flex and accomodate in order to focus on objects at a broad range of distances.  The Crystalens dynamically adjusts to your visual needs while maintaining superior quality vision.  It not only treats your cataracts, but addresses your full range of vision. If you're like many Crystalens patients, you'll hardly, if ever, need your glasses or contact lenses again.

Crystalens: The effectiveness of the Crystalens© was proven in clinical trials:

• 98.4% of patients implanted with Crystalens© in both eyes could pass a driver's test without glasses
• 100% could see intermediate (arm's length vision) without glasses, the distance for most of life's activities
• 98.4% could see well enough to read the newspaper and the phone book without glasses
• 74% of patients never or almost never wore eyeglasses

Significantly more patients implanted with a Crystalens© (88.4%) could see better at all distances than patients implanted with a standard IOL (35.9%).

Long term results with the Crystalens means a safe and effective procedure and more than 150,000 have been implanted.

Finally, the opportunity for freedom from reading glasses and bifocals.

Until recently, life without reading glasses or bifocals wasn't an option for most cataractCataract: A "clouding" of the lens in your eye. As light passes through the cataractous lens, it is diffused or scattered, resulting in blurred or defocused vision. patients. You now have that option. The AcrySof® IQ ReSTOR® IOLIntraocular lens (IOL): An artificial lens that is implanted in the eye during cataract surgery to replace the eye's clouded crystalline lens. is a unique technological innovation that can provide you with enhanced image quality and a full range of vision – near, far and everywhere in-between – for increased independence from reading glasses or bifocals!

How does the AcrySof® IQ ReSTOR® IOL work?

As we perform daily activities such as reading, watching television or working at the computer, our eyes are constantly focusing on objects at varying distances – up close, far away and in-between. The ability to quickly change focus throughout our range of vision is called accommodationAccommodation: The ability of the eye's natural lens to change shape to focus on objects at various distances.. Unfortunately, we begin to lose this ability as we grow older1, gradually becoming more and more dependent on bifocals or reading glasses. Thankfully, by combining the strengths of apodized diffractive and refractive technologies, the AcrySof® IQ ReSTOR® IOL can now provide quality near, intermediate and distance vision, and increased independence from reading glasses or bifocals. And now, with the addition of proven aspheric technology, the AcrySof® IQ ReSTOR® IOL takes the advancements one step further, for a lens with enhanced image quality and clarity.

Apodized Diffractive Technology

DiffractionDiffraction: The spreading of light that occurs when light passes through discontinuities (i.e., the steps or edges of a lens). In an optical system, light can be diffracted to form multiple focal points or images. involves the spreading of light as it passes through a lens. You'll notice that, on the AcrySof® IQ ReSTOR® IOL, the center of the lens surface consists of a series of tiny rings – this is known as an apodized diffractive optic. ApodizationApodization: The gradual reduction or blending of varying diffractive step heights. The application of apodization to intraocular lenses is a patented process by Alcon and can only be found in the AcrySof® IQ ReSTOR® IOL. is the gradual tapering of different diffractive levels (or "steps") on a lens, creating a smooth transition of light between distant, intermediate and near focal points. This means is that the series of tiny steps in the center of the AcrySof® IQ ReSTOR® IOL work together to focus light, providing excellent nearNear vision: The range of vision that includes focal points 16 inches or closer to your eyes. Items that typically fall within this range include books, newspapers and medicine bottles. Also known as "reading vision.", intermediateIntermediate vision: The range of vision that includes focal points between 16 inches and 7 feet away from your eyes. Items that typically fall within this range include computer screens and car dashboards. and distance visionDistance vision: The range of vision that includes focal points 7 feet or further from your eyes. Items that typically fall within this range include billboards, street signs and movie screens..

Refractive Technology

RefractionRefraction: Redirection of light rays as they pass through a lens. involves the redirection of light as it passes through a lens. The outer ring of the AcrySof® IQ ReSTOR® IOL is a refractive region designed for excellent distance vision. This refractive area bends light as it passes through the lens, accurately focusing it on the retinaRetina: The transmitter located at the back of your eye that sends the images to your brain. for a crisp, clear image.

Aspheric Technology

Even healthy eyes still contain some imperfections, or "aberrations." Spherical aberrationSpherical aberration: An irregularity in the shape of the lens. As the eye ages, the lens gets thicker and rounder, causing image quality to deteriorate. Often associated with loss of contrast sensitivity and poor night vision., a type of imperfection common to cataract patients, can eventually lead to a reduction in visual acuity and function. Thankfully, with the addition of a proven aspheric opticAspheric optic: A type of lens designed to compensate for spherical aberration, resulting in improved image quality., the AcrySof® IQ ReSTOR® IOL can correct for these spherical aberrations, leading to enhanced clarity.
