An intraocular lens (IOL) is the replacement lens that is surgically implanted in the eye to replace the existing clouded lens during cataract surgery.
The good news is that you’ve encountered cataracts at a time when intraocular lens technology has taken great leaps of progress. Traditionally, the replacement lens used for cataract surgery was a monofocal IOL. This type of lens restored good functional distance vision, but people still needed to continue wearing reading glasses. Today, you also have the option of a multifocal lens, which can improve vision in a full range of distances from near to far.
The multifocal lens is a breakthrough lens for cataract surgery that lets patients see from near to far, usually without glasses. An innovative optical technology makes this lens uniquely effective, especially when placed in both eyes. A similar technology has been used for years in microscopes and telescopes to improve image quality and has now been patented for use in intraocular lenses.
Most multifocal lens patients find that they can read a book, work on the computer, drive a car – day or night – and play golf or tennis with an increased freedom from glasses.
Cataract surgery with the multifocal lens enables most people to see the big picture without missing the details, usually without glasses. Such dramatically improved eyesight immediately multiplies the possibilities in your life. Passengers could become drivers again. Golfers could keep their eye on the ball and enjoy the surrounding scenery. Travelers on safari could spot animals and identify them in their guidebook, not mention see the expressions on everyone else’s face.
Your doctor will go into detail, offer a comprehensive evaluation, as to whether you are a candidate for this exciting technology. There will also be a discussion about what you can expect, including side effects which are usually temporary.
Other Lens Options
The replacement lens (IOL) may also be used to correct distance and near vision. Astigmatism can also be corrected with this lens!
