Intraocular Lens Implant Types

Intraocular Lens Implants or IOLs are artificial lenses that are used to replace natural lenses that have become clouded with Cataracts. They can also be used as a solution for people who suffer from presbyopia, a condition in which the lens becomes less flexible thus losing its ability to focus on near objects. There are a number of types of Intraocular Lens Implants (IOL) that can be used today. 

Monofocal Lens Implants (IOL) vs. Multifocal Lens Implants (IOL)

The traditional type of intraocular lenses are called Monofocal Lens Implants and are used to correct problems with distance vision leaving patients to rely on glasses or contacts for near vision. At Baltimore Washington Eye Center Drs. Betancourt and Spagnolo offer our patients Multifocal Lens Implants to help them see more clearly at a range of distances. This technology allows us to replace the eye’s natural lens with a new artificial lens that can help restore visual clarity to near, intermediate and distance vision.

Astigmatism Correcting Toric IOLs

If you have astigmatism, you may still experience blurred and distorted vision after traditional Cataract Surgery unless you wear eyeglasses because ordinary Monofocal IOLs cannot correct astigmatism. If freedom from glasses for distance vision is important to you, you now have a better option. The unique design of a toric IOL makes it possible to reduce or eliminate astigmatism and significantly improve uncorrected distance vision and may reduce or eliminate the need for corrective lenses for seeing at a distance for those patients who had astigmatism before their Cataract Surgery.

Spherical Aberration and Cataracts

Your eyes contain some imperfections called aberrations. An aberration is an irregularity in the shape of the eye's refractive surface that can distort vision. One type of common aberration is spherical aberration. Spherical aberrations are generally associated with:
  • Blurriness
  • Halos
  • Loss of contrast
  • Poor night vision
Drs. Betancourt and Spagnolo often implant an Aspheric Lens Implant designed to reduce spherical aberration and improve contrast sensitivity in order to help patients see better in low contrast environments such as for driving in dim illumination or during rainy, foggy times. Aspheric Lens Implants offer these advantages over traditional lens implants and some can even correct astigmatism.
