Multifocal and Accommodative IOL Surgery (ReSTOR® Lens, Crystalens®, TECNIS®, and Toric Lens)
Several new intraocular lenses (IOLs), called multifocal and/or accommodating IOLs, have been introduced in recent years that utilize advanced technology to achieve good distance, intermediate and near vision without glasses. One such lens is the AcrySof® IQ ReSTOR® lens, a breakthrough lens that uses apodized diffractive technology (similar to technology used in telescopes and microscopes) to give patients a full range of vision – near through distance – and to reduce dependency on reading glasses or bifocals following cataract surgery. This means that many patients can read the text on items such as prescription bottles, magazines, newspapers and computer screens, while also providing the ability to see items at a distance free from glasses or bifocals.
AcrySof® IQ ReSTOR® Intraocular Lens
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 everything in-between. The ability to quickly change focus throughout this range of vision is called accommodation. Unfortunately, this ability diminishes as we grow older, causing us to become 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.
According to the AcrySof® IQ ReSTOR® IOL clinical studies, three out of four patients implanted in both eyes with the AcrySof® IQ ReSTOR® reported never wearing glasses following cataract surgery. Additionally, the AcrySof® IQ ReSTOR® IOL clinical studies indicate that over 95% of the study subjects were so satisfied with their new quality vision that they would have the AcrySof® IQ ReSTOR® IOL implanted again.
Multifocal IOLs have a slightly greater tendency to cause night vision complaints than other IOLs, so those who drive a great deal at night may wish to consider a different IOL. The vast majority of patients with these IOLs, however, are not bothered by night vision complaints. Additionally, multifocal lenses usually need to be implanted in both eyes before full adaptation can occur.
Crystalens® Accommodating Intraocular Lens
Crystalens® accommodating lens, unlike other lens technologies, uses 100% of the available light rays. Working in concert with the eye’s natural muscle, Crystalens® "flexes" to accommodate near, intermediate and distance subjects. Just as the human lens uses the Your browser may not support display of this image. ciliary muscle to move the lens thus allowing a person to focus on the subject at hand, the Crystalens® works in a similar way. The lens rests back in the eye to accommodate distance vision, then gently flexes forward to accommodate intermediate vision, and then flexes further forward for near vision. This movement is enabled by a flexible hinge within the lens.
Crystalens® is the first and only FDA-approved accommodating IOL. Your physician will perform a thorough eye exam to determine if you are a candidate and will fully inform you of any increased risk of complication.
TECNIS® Multifocal Intraocular Lens
Designed to give patients back their youthful vision, the TECNIS Multifocal Lens, provides patients with high-quality vision at any distance, and in any light condition — even in low light. Just introduced by Abbott Laboratories, the advanced TECNIS Multifocal is the only full-surface "diffractive aspheric" IOL. It enables patients to function comfortably without glasses at near, intermediate and far distances. Based upon initial studies, it’s the lens 94% of patients would choose again and nearly 9 out of 10 study patients did not require glasses after their cataract surgery.
If you are diagnosed with cataracts and are experiencing one or more of the following symptoms, you may be a candidate for the TECNIS Multifocal Lens:
- Difficulty reading
- Difficulty seeing close objects
- Difficulty seeing to drive, especially at night
- Changing glasses prescriptions
- Needing bifocals
Ask your doctor if the TECNIS Multifocal Lens is an option that is right for your lifestyle and eye health.
