The specialty of ophthalmology has advanced dramatically, particularly in the area of cataract surgery and how easily and accurately it restores clear vision. If you have cataracts and think it may be time for surgery, you should ask your ophthalmologist about intraocular multifocal lenses. They can give you back natural, clear vision whether you are looking at something near, something in the distance, or somewhere in between.
Details on Multifocal Lenses
Also known as presbyopia intraocular lenses, multifocal lenses allow for normal vision–close, distant, and in-between–after cataract surgery. These silicone or acrylic lenses work within the structure of the eye, allowing for sharp, clear, colorful images. They replace the natural lenses in the eye which, with age and other influential factors, become clouded and discolored due to cataracts.
Most people who undergo cataract removal surgery–in fact, up to 4 million annually in the US–opt for what’s called multifocal lenses, intraocular lenses, or IOLs. These intraocular lenses approximate natural, youthful vision in amazing ways.
Monofocal intraocular lenses usually produce excellent distance vision focusing but cannot accommodate midrange or up-close images. However, some kinds of multifocal lenses work almost seamlessly with the patient’s brain to bring numerous focal distances into sharp focus. Toric multifocal lenses accommodate the special vision needs of individuals who have astigmatisms, or errors in refraction due to odd curvatures in the cornea.
Are Multifocal Lenses the Right Choice for You?
This is something to discuss with your ophthalmologist. The doctor will examine your eyes with special attention paid to the lens which brings light into focus on the highly vascularized retina. The retina then sends these images via the optic nerve to the brain for interpretation.
When cataracts are severe enough to produce halos around lights, reduce contrast and discolor and distort images, then it likely is time for surgery. This vision deterioration only worsens with age, exposure to sunlight, certain medications, and even heredity.
Regarding lens choice, you should consider the extra cost of multifocal lenses. Most health insurance only covers mono-focal lenses, and the patient must pick up the extra cost of the multifocal IOLs.
