Active Life-Style Lens Options


Selecting Your Intraocular Lens

The decision as to which type of lens implant you want is an important one because it will affect how you see for the rest of your life.

  • Monofocal IOLs: These provide a single zone of clear focus and are usually targeted to provide good distance vision when patients do not have astigmatism. Patients receiving Monofocal IOLs typically require the use of bifocals or reading glasses after surgery.
  • Monofocal Toric IOLs: These are specialized Monofocal lOLs that also correct astigmatism.
  • Multifocal IOLs: These provide a wider range of vision for distance and near and in most patients eliminate the need for glasses altogether

Tecnis Multifocal Lens

Tecnis Multifocal LensThe advanced Tecnis Multifocal Lens is an implantable lens that significantly improves vision after cataract surgery and corrects presbyopia; a common age-related condition, beginning around the age of 40 when the natural lens inside the eye begins to harden and becomes less flexible. This reduces the eye's ability to switch focus from near, far and in between, and back again.

The multifocal lens implant helps replace reading glasses or bifocals. This lens lets patients see in the distance and then immediately look down and read without needing to use either distance or reading glasses. The eye automatically focuses from far to near and back again immediately, and as often as needed.

Immediately after surgery, some patients may notice rings around lights when driving at night. However, as the eye adjusts to the lens over time, the visual impression of rings typically lessens or goes away. Most patients don't comment on them at all. A patient wanting to enjoy freedom from glasses after cataract surgery might be a good candidate for the multifocal lens.


Crystalens LensCrystalens is an accommodating intraocular lens that, unlike a standard IOL, can treat both a person's cataracts and presbyopia—loss of near and intermediate vision. You probably noticed in your forties that you started to lose some of your up-close vision and had to start wearing reading glasses. Crystalens not only treats your cataracts (a clouding or hardening of your lens) but can also reduce or eliminate your dependence on glasses. It does so by recreating accommodation similar to your eye's natural lens. The unique Crystalens can reduce or eliminate glasses for most activities, including reading a book, working on the computer, and driving a car.

Crystalens was modeled after the human eye. Like the natural lens, it uses the eye muscle to flex and accommodate in order to focus on objects in the environment at all distances. Crystalens dynamically adjusts to your visual needs.

Crystalens is:

  • The first and only FDA-approved accommodating intraocular lens
  • The only FDA-approved intraocular lens that uses the natural focusing ability of the eye
  • The only FDA-approved presbyopia-correcting IOL for cataract patients that provides a single focal point throughout a continuous range of vision

Few patients with Crystalens have experienced problems with glare, halos and night vision. Crystalens focuses only on one image to the back of the eye, unlike a multifocal lens that projects multiple images, requiring your brain to “adjust” to the differences.

The Greater New Bedford Surgical and Laser Center

The Greater New Bedford Surgical and Laser Center was opened in 1986 with the express purpose of rendering high quality, state of the art eye surgery to patients of all ages, especially those with cataracts, glaucoma, or cornea disease. The Center is designed specifically with the needs of the patient in mind. The entire process from initial examination to final outcome is conducted in a pleasant comfortable environment.

After a patient decides to have surgery, he or she is assigned his or her own Surgical Counselor who is available to answer questions and provide assistance. These individuals are specially trained to assist the patient throughout the entire surgical experience, including follow up care for as long as necessary. Patients are encouraged to contact their counselor for any questions, no matter how simple or complex.
