Intraocular Lens Implant (IOL) Information

Intraocular Lens Implants, Intraocular Lenses, Lens Implants or IOLs are tiny plastic artificial lenses that are used to replace eye’s natural crystalline lenses that have become clouded with cataracts or to treat the common age related problem of presbyopia. Presbyopia is a condition in which the crystalline lens becomes less flexible, thus losing its ability to focus on arm’s and near objects. Today there are several types of lens implants that can be used to correct vision when a cataract has been removed. Here is what you should know:

Monofocal Lens Implants vs. Multifocal Lens Implants
The traditional type of lens implant is called a Monofocal Lens Implant because it offers patients improvement in vision at one set distance distance-usually for seeing far away. More that 75% of patients who have Monofocal Lens Implants require reading glasses, bifocals or trifocals in order to see up close or at arm’s length after Cataract Surgery. Dr. Leslie Doctor offers patients at Doctor & Associates the opportunity to have Multifocal Lens Implants. This advanced lens implant technology allows her to replace the eye’s natural lens with a new artificial lens that can help restore visual clarity to near, intermediate and distance vision with a reduced need for or even complete independence from eyeglasses.

Astigmatism Correcting Toric Lens Implants
If you have astigmatism before cataract surgery, you may still experience blurred and distorted vision after traditional cataract surgery because a traditional lens implant cannot correct astigmatism. If you have astigmatism before cataract surgery you may still require glasses, contact lens or further surgery to get clear vision. If freedom from glasses for distance vision is important to you, you now have a better option. Dr. Leslie Doctor implants astigmatism correcting lens implants where the unique lens design makes it possible to reduce or eliminate astigmatism and significantly improve your uncorrected distance vision so that you may reduce the need for corrective lenses compared to a traditional IOL.

Aspheric Lens Implants
Most eyes have optical distortions-called aberrations-that cause a number of vision problems for patients. One type of aberration commonly that is particularly troubling to patients is called spherical aberration. Spherical aberration can lead to a reduction in vision acuity and function. Spherical aberration is generally associated with:
  • Blurriness
  • Halos
  • Loss of contrast
  • Poor night vision
If you have spherical aberration and are having Cataract Surgery, Dr. Leslie Doctor can implant a lens designed to reduce spherical aberration so that you experience an increase in contrast sensitivity that will help you see in dim illumination, foggy and rainy conditions and at dusk. Patients who have aspheric lens implants typically appreciate enhanced clarity and improved image quality.
