Cataracts

A cataract is any opacity to the lens inside the eye.  This clouding will cause blurred vision along with other visual disturbances such as glare.  CataractCataracts will make it more difficult to drive especially at night due to the glare.  It can also affect quality of life in how you’re able to do things such as hobbies and leisure activities.  There are now many surgical options ranging from traditional implants to the new and improved multi focal implants.  These new lenses can allow patients to see both far distances and up close for reading without the use of glasses.

Corrective lenses / Implant options:

1.)  Conventional lenses.  These lenses would replace your cataracts, and both eyes would be corrected for far vision.  Measurements made prior to surgery allows the surgeon to choose a lens that can allow you to either need no glasses for distance tasks, or require only a minor prescription.  You will need reading glasses for near tasks with this option.

2.) Monovision with conventional implants.  This form of correction would make one eye for distance and one eye for near.  This may allow you to see both far and near without glasses.  We don’t usually recommend this unless a patient has first tried this with contacts or lasik.

3.)  Toric implants.  These are a special kind of conventional lens, and they can correct your astigmatism inside the eye.  The goal is to make you much less dependent on glasses, and it works much like option 1.  These are not yet available in multifocal lenses.

4.)Multifocal lenses.  These are the newest and most technologically advanced lenses available to patients.  These have variable zones on the implant that allows the lens to give both far and near correction simultaneously.  These may not be for everyone depending on your current glasses prescription, but for many, they’ve given patients the ability to not need glasses at all after surgery.

Names of multifocal lenses:  Restor, Rezoom, Crystalens.  These lenses don’t yet correct for astigmatism, but that option should be available late 2011 or early 2012.

There are many choices for the types of implants that are available, and the wrong choice could have lasting affects on our vision.  Please call and make an appointment so we can help you make the best decision for your eyes.
