Premium Lens (IOL) Implant Options
Cataract surgery remains the most frequently performed surgery in the United States and is arguably the safest surgery performed as well. The surgery itself remains unchanged but the lens technology has improved dramatically. If you had quality distance vision as well as potentially near vision following cataract surgery without the need for glasses or contacts, your quality of life would dramatically improve. Cataract surgery is a once in a lifetime surgery. You are given the choice of vision correction options and lens, thus making one of the most important health decisions.
Previously, individuals suffering from cataracts had only a standard lens implant option (monofocal) as an option. With advancements in lens technology, there are a number of intraocular lenses available including: accommodative, multifocal and toric implants. Dr. Adelson will help determine which IOL is best for you based on the unique characteristics of your eye and your overall needs.
1. Accomodative Implants
The Accommodative IOL is designed to mimic the movement of the natural lens of the eye. The natural lens is flexible and easily moves back and forth within the eye as we change our visual focus from up close to far away. As we get older, the eye loses its flexibility and can no longer easily accommodate changes in our focus. To mimic the natural lens, the accommodating IOLs are able to move and change shape inside the eye to allow focus at multiple distances. Even with this technology advancement, accommodating IOLs are able to provide some range of focus, but cannot make an exact copy of the vision you had in your 20’s.
See CYSTALENS for more details.
2. Multifocal Implants
With bifocal glasses, the focus changes depending on the area of the lens you look through. A multifocal lens implant provides several zones of focus simultaneously. Your brain will learn to automatically select the focus that is appropriate for the task at hand. This is very much like having a conversation in a room where there is background music and you have the ability to ignore to listen to each other.

3. Toric Implants
Patients who have significant amounts of astigmatismmay want to consider and discuss with Dr. Adelson their candidacy for a specialty implant called a toric intraocular lens. Astigmatism is a focusing problem caused by the irregularly curved surface of the eye, creating blurred and
double images when viewing objects at any distance. Standard monofocal, multifocal and accommodating IOLs can improve nearsightedness and farsightedness, but not astigmatism.
Toric IOLs are uniquely designed to reduce astigmatism and may be an option for patients who are having lens exchange surgery with or without cataracts. To obtain the best vision without glasses following lens surgery, the Toric IOL is the best option for patients with significant astigmatism.
See Toric IOL for more details.
4. Monofocal Implants
These lenses remain the standard lens commonly implanted with cataract surgery and the lens that all patients had implanted prior to the premium lenses coming into existence. Not everyone is a good candidate for the ReSTOR or Crystalens, and not everyone has astigmatism and needs the Toric lens. More than 70% of the lenses that we use today are still monofocal lenses. The drawback to this lens is it does not correct for astigmatism and it does not correct for near vision so reading glasses will still be required. These lenses are typically covered by Medicare and most other insurance plans.
