Multifocal Intraocular Lens Implants
"An intraocular lens implant is an artificial replacement for the lens of your eye. It's part of the surgery to fix cataracts.
Implanting Multifocal IOLs
An intraocular lens implant, or IOL, is made of a clear plastic, and it's about a third the size of a dime.
There are several different types:
Monofocal IOL: This is the most common. Unlike your natural lens, which can stretch or bend to help your eye focus, this implant stays focused at one fixed distance. If yours focuses at a distance, you might be able to see things far away but need glasses to read or see close up.
Multifocal implant: Like glasses with bifocal or progressive lenses, this lens has areas that help you see things at different distances. It could take several months for your brain to adapt so your vision seems natural.
Toric IOL: You'll get this is if you have astigmatism, or a cornea that's more football-shaped than round. This can make vision blurry all over, not just close up or far away. This lens lessens astigmatism so you won't need glasses to correct it after your surgery.
If you have a cataract, you'll see an ophthalmologist. This doctor specializes in eye problems. He'll probably tell you it's best to wait to remove the cataract until it starts to affect your daily life. He can do the surgery at a hospital or an outpatient clinic."
