Mono vs. Multifocal IOLs

by: Advanced Laser | July 23, 2012

With over 22 million Americans affected, cataracts are the most common cause of vision loss in patients over the age of 40. Cataracts can greatly decrease the quality of your vision, so it’s important to visit a skilled Oklahoma City eye doctor for treatment. At the Advanced Laser and Cataract Center, Dr. John Belardo features the latest technology for patients with cataracts, including ReSTOR® multifocal intraocular lenses.


A cataract is a buildup of protein in the eye that results in a cloudy eye lens. Cataracts cause many problems, including blurred, dim vision; halos or glares; and difficulty seeing at night. Cataracts may affect one or both eyes, and can only be corrected with cataract surgery.

Cataract Surgery

Although many patients develop cataracts, they can be successfully treated with cataract surgery, a commonly performed vision procedure. There are several different types of cataract surgeries available to effectively restore a patient’s vision. Before performing any procedure, Dr. Belardo first meets with patients for a consultation to determine what surgical options will best fit your needs, including what type of replacement lens (IOL) to use. Cataract surgery is a quick, painless procedure requiring no stitches, and is usually completed in about 30 minutes. During cataract surgery, Dr. Belardo carefully removes the cloudy lens of the eye through a small incision and replaces it with a clear synthetic lens, called an intraocular lens, or IOL. Once in place, IOLs are permanent, and do not require any additional care after the eye has healed.

Monofocal vs. Multifocal Intraocular Lenses

There are two main types of IOLs: multifocal and monofocal. The difference between the two types of lens implants is actually similar to the difference between monofocal and bifocal glasses.

  • Monofocal IOLs are focused at a precise point, and usually require reading glasses or contact lenses in order to augment close-distance vision.
  • Multifocal IOLs enable patients to see near, intermediate, and far distances, often without the aid of glasses. Multifocal lenses can also be used to treat presbyopia, an age-related condition that causes patients to lose their ability to focus clearly on objects in close range.
