Intraocular Lens Implants (IOLs)

There are three types of IOLs that are used to replace the natural lens once it is removed during cataract surgery. A lens implant is essential to focus light to the retina where images are captured and then sent to the brain allowing us to see. There is one type of “standard” lens and two types of Advanced Technology lenses.

Monofocal IOLs (Standard)

Monofocal IOLs focus light from only one set point in space, usually distance. These lenses allow for clear vision without glasses at a point predetermined by the patient and surgeon. Most patients elect to have Monofocal IOLs set for clear distance vision. Patients understand that they will need glasses to focus at intermediate and near distances such as when working on the computer and reading.

Some patients elect to have one eye focused at distance and the other eye focused at near. This choice is called Monovision and uses monofocal IOLs to help patients be free of glasses. However, some people cannot adapt to the difference in focus between their eyes. Monovision can be simulated with a contact lens trial and is highly recommended prior to surgery.

Advanced Technology IOLs

Multifocal IOLs

Restor IOL image exampleThe newest technology available are Multifocal IOLs. These lenses are designed to correct both cataracts and Presbyopia, or the inability to see at intermediate and near affecting almost everyone over the age of 40. These special lenses aim to restore vision at distance, intermediate, and near without the need for glasses. Multifocal IOLs use special technology incorporated into the design of the lens to provide its special focusing power. For patients who want to see at all ranges, Multifocal IOLs are becoming the most commonly chosen and most popular lens implants for patients undergoing cataract surgery. Not all patients are candidates for Multifocal IOLs. To see if you are a candidate and can benefit from this advanced technology, make an appointment with us for a thorough consultation.

Toric IOLs

Toric IOL image ExampleSome patients with cataracts also suffer from high levels of Astigmatism. Astigmatism results from an abnormal shape of the cornea (the front windshield of the eye). In patients with astigmatism, the cornea is more cylindrical like the shape of a football, rather than more spherical like the shape of a basketball. Astigmatism produces blurred images, which more often than not cannot be corrected fully with glasses. Many patients with higher levels of astigmatism choose Toric IOL implants. Toric IOL implants can fully correct both cataracts and higher levels of astigmatism giving patients the clearest and sharpest vision possible. To see if you are a candidate and can benefit from this advanced technology, make an appointment with us for a thorough consultation.
