A cataract clouds the eye’s natural lens, leading to significant visual distortions that can affect your ability to see clearly. Eventually, the natural lens will need to be removed and replaced with an artificial intraocular lens (IOL) that provides clear vision.
While most patients pick monofocal IOLs, many patients choose multifocal IOL lenses. Discuss with your [eye_ doctor] which type of IOL is right for you.
What Is a Multifocal Intraocular Lens?
A multifocal IOL allows patients to see all distances clearly. These IOLs allocate different optical powers on the IOL. The varying optical powers are created by the IOL design, which incorporates concentric rings on the surface of the lens. These allow images at a variety of distances to be in sharp focus.
It can take some time for people to adapt to multifocal IOL lenses because the focusing power the lenses provide is different from what people are accustomed to. Since the IOL relies on a different design than the bifocal or multifocal optical lenses used in eyeglasses, the brain might need time to adjust.
To ease the adjustment, most cataract surgeons recommend having multifocal IOLs implanted in both eyes, rather than just one.
Are Multifocal IOLs Right for You?
If you are looking for an IOL that can provide you with clear vision for reading, driving and watching TV, a multifocal IOL may be just right for you.
After cataract surgery, multifocal IOLs can reduce the need for reading glasses or computer glasses. These implanted lenses widen your field of vision, allowing you to see well both up close and far, often without the use of glasses. Many patients who choose multifocal IOLs find that they can go glasses-free or only occasionally need reading glasses for small print after surgery.
Despite the obvious benefits of these lenses, they may not be suitable for everyone. Some patients find that it takes longer to adapt to multifocal lenses than to monofocal lenses. Contact Richmond Hill Optometric Clinic Lasik & Cataract Surgery Center to discover whether IOL multifocal lenses are right for you.
Q: How does a multifocal IOL work?
- A: When wearing bifocal or multifocal glasses, you look through the bottom part of the lens for near vision and through the top part of the lens for distance vision. A multifocal IOL is specially designed to provide clear vision at all distances at all times. Your brain adjusts, allowing you to see clearly for the task at hand.
Q: Will a multifocal IOL eliminate the need for glasses?
- A: Most people find they do not need glasses with multifocal IOLs, but some do, depending on the situation. There may be times when the print or graphics are simply too small or too far away to be seen without glasses.Richmond Hill Optometric Clinic Lasik & Cataract Surgery Center serves patients from Richmond Hill, Markham, North York, and Vaughn, all throughout Ontario.
