Wider-range lenses. Some lenses help you see clearly at more than one distance. Multifocal lenses use two focal points; trifocal lenses have three; extended depth-of-focus lenses provide excellent intermediate and distance vision and some up-close vision.
Multifocal lens implants can correct both near- and far-sightedness following cataract surgery, thanks to concentric rings etched into them which allow multiple distances to focus simultaneously on the retina.
Choosing the best lens for cataract surgery can make a world of difference in your vision. Our clear guide helps you navigate options, from monofocal to multifocal lenses, empowering you to regain clarity and embrace life's vivid moments with confidence.
The benefits of multifocal lenses for cataract surgery include improved near and distance vision, reducing the need for reading glasses. When choosing multifocal lenses, considerations such as lifestyle, visual needs, and potential side effects should be taken into account. Potential drawbacks of multifocal lenses include glare, halos, and ...
The four main types of cataract lenses are monofocal lenses, multifocal lenses, extended depth of focus (EDOF) lenses, and astigmatism-correcting toric lenses.
Cataract surgery is a procedure to remove the lens of the eye and, in most cases, replace it with an artificial lens. A cataract causes the lens to become cloudy when it is typically clear. Cataracts can eventually affect vision.
Cataract surgery involves replacing the eye’s cloudy lens with a synthetic intraocular lens (IOL) to restore clear vision. One of the choices available to patients is a multifocal IOL, designed to offer different levels of vision correction, allowing clear vision at various distances.
By Vance Thompson, MD. If you need cataract surgery and you want the greatest freedom from eyeglasses after surgery, you might want to consider multifocal intraocular lenses (IOLs) to expand your range of clear vision.
IOLs (intraocular lenses) are clear, artificial lenses that replace your eye’s natural ones. You receive IOLs during cataract surgery and refractive lens exchange. IOL implants correct a range of vision issues, including nearsightedness and age-related farsightedness. They may also help reduce your reliance on glasses for certain types of tasks.
Multifocal IOLs have corrective zones built into the lens, much like bifocal or trifocal eyeglasses. This allows you to see both near and far objects. Some multifocals may also correct intermediate vision. Extended depth-of-focus (EDOF) IOLs have only one corrective zone. But this zone is stretched to allow distance and intermediate vision.
