Cataract Implants|Premium IOLs (Intraocular Implants)


When you have cataract surgery, we will replace your natural lens with an artificial cataract implant. This is done to correct your vision and minimize the need for glasses after cataract surgery. During cataract surgery, a cataract implant is always placed into the eye. There are 3 categories of cataract implants. We can implant :

  • monofocal cataract implants
  • toric cataract implants
  • presbyopic cataract implants

At the Eye Surgery Institute, we will perform a comprehensive examination and provide you with the best implant options available. We will base our recommendations on the health of your eye and your individual needs and goals.

Monofocal implants

A traditional monofocal intraocular lens implant (IOL) is used to restore distance vision. You will typically still use glasses for reading and when on the computer. Monofocal implants are the traditional implants and until recently were the only option available.

A monofocal implant is covered by your medical insurance at the time of cataract surgery. A monofocal implant may be a good option if you do not mind wearing glasses after cataract surgery or if you have other eye diseases that cause you to not be a candidate for other implant options.

Toric implants correct astigmatism

Patients with astigmatism may obtain better vision with a toric intraocular lens.

Toric intraocular implants correct astigmatism. Astigmatism means the cornea is shaped more like a football than a basketball. This can make the vision distorted at all distances without glasses. If astigmatism is not corrected at the time of cataract surgery, you will still need glasses after the surgery for all activities (distance, intermediate and near vision).

Standard intraocular lenses (monofocal IOLs) do not correct astigmatism. I use the Alcon Acrysof toric intraocular lens to reduce dependence on glasses after cataract surgery.

Presbyopic implants

Premium intraocular lenses can improve both distance and reading without glasses at the same time.

The Alcon Restor and Tecnis multifocal allow you to see better at both distance and reading without glasses. These presbyopic premium IOLs are designed to restore a full range of vision and reduce the need for reading glasses or contacts after cataract surgery. You may be a good candidate for a presbyopic premium IOL if you have a desire to be less dependent on glasses and have a healthy eye. I will peform a comprehensive eye examination to determine which options are best for you.
