Artificial lenses (IOLs) are implanted in the eye to replace natural lenses for patients with cataracts, presbyopia or severe refractive errors. Until recently, IOLs were only available to correct distance vision. These monofocal lenses helped improve distance vision after cataract surgery, but patients still needed glasses or contact lenses for near vision activities like reading and playing cards. Now, advancements in technology have produced multifocal IOLs that allow patients to see clearly at all distances — near, far and many distances in between. Multifocal IOLs such as ReStor® and Tecnics™ preserve distance vision and correct presbyopia so cataract surgery patients — and patients seeking treatment for refractive errors alone — can enjoy clear sight without relying on glasses.  Toric IOLs are specially designed for patients with pre-existing astigmatism and are used instead of, or in addition to, limbal-relaxing incisions.

Clear Lens Extraction replaces the natural lens with a multifocal IOL for patients wishing to correct high farsightedness, high nearsightedness or presbyopia without undergoing a corneal modification procedure such as LASIK.

If you have been diagnosed as having cataracts and are experiencing one or more of the following vision problems, you may be a candidate for a multifocal IOL:

  1. Difficulty reading
  2. Difficulty seeing close objects
  3. Difficulty driving, especially at night
  4. Frequent changes in glasses prescription
  5. Need for bifocals

ReSTOR® LensUsing apodization, diffraction and refraction technologies, the ReSTOR® lens improves upon ordinary replacement lenses (IOLs) by providing comprehensive focusing capabilities so patients can see clearly in a range of lighting conditions and at all distances — at noon or midnight, nearby or far away, and many distances in between. Up to 80% of patients who use the ReSTOR® lens don’t need to rely on glasses or contact lenses after surgery.

TECNIS® MULTIFOCAL LENS
The advanced TECNIS® Multifocal is an implantable lens that significantly improves vision after cataract surgery and corrects presbyopia. Designed to help you regain younger vision and be free of glasses, the TECNIS® Multifocal Lens can provide you with high-quality vision at all distances and in all lighting conditions—even in dim light.
If you enjoy activities such as reading, boating, quilting, playing golf, sightseeing, or surfing the Internet, the TECNIS® Multifocal Lens allows you to lead an active lifestyle.


Toric IOLs
Some people with astigmatism and cataracts may benefit from the implantation of toric IOLs instead of, or in addition to, limbal-relaxing incisions. Specially designed for patients with pre-existing astigmatism, toric lenses improve vision from cataracts and astigmatism at the same time. Patients enjoy a quick recovery.

Limbal-relaxing Incisions (LRI)
Patients with astigmatism who are undergoing cataract surgery can choose to have limbal-relaxing incisions made to reduce their dependence on glasses for clear vision. Limbal-relaxing incisions are tiny cuts made around the edge of the cornea, called the limbus. These incisions “relax” the cornea’s steep curvature and improve the way the eye focuses light. Limbal-relaxing incisions have been shown to heal faster and cause fewer side effects than other astigmatic keratotomy (AK) procedures.

 

Clear Lens Extraction (CLE)
Clear lens extraction replaces the natural lens with a multifocal IOL for patients wishing to correct high farsightedness, high nearsightedness or presbyopia without undergoing a corneal modification procedure such as LASIK. The procedure is the same as that used in cataract surgery; the only difference is that CLE is performed to achieve refractive correction rather than cataract removal. CLE has a low risk of side effects, involves a rapid recovery, and offers patients dramatic improvement in vision quality. After surgery, patients enjoy clearer vision and greater focusing power.
You may be a candidate for clear lens extraction if you:

  1. Want to reduce or eliminate your dependence on glasses or contacts
  2. Are over 50 years old
  3. Have high myopia (nearsightedness), high hyperopia (farsightedness), or presbyopia, with or without cataract
