What Is Cataracts?

Cataracts

Cataracts

The natural lens of the eye helps to focus light on the retina inside the eye to produce clear images.  A cataract is a clouding of the eye’s natural lens as people age.  A cataract can also be caused from an eye injury, certain diseases, certain medications or long-term exposure to sunlight.   It is one of the leading causes of vision loss in the United States.

A cataract can be the reason that objects become blurred, bright colors seem dull, or seeing at night becomes more difficult.  Occasionally, changing your eyeglass prescription may help to improve your vision for a while.  When you can no longer see well enough to do the things you like to do, cataract surgery should be considered to improve your vision.  To determine if your cataract should be removed, your ophthalmologist will perform a thorough eye examination.

Cataract Surgery

Cataracts Surgery

In cataract surgery, the cloudy lens is removed through a tiny incision.  After the cataract is removed, the natural lens is replaced with a permanent lens, called an intraocular lens implant (IOL).  These IOLs come in different focusing powers.  At your evaluation, your eyes will be measured to determine the proper focusing power of the IOL for your eyes.  Different IOL options are available to help give you the best vision to complement your own individual lifestyle.

All Laser Cataract Surgery

LenSx Laser

LenSx Laser can correct for this low astigmatism by creating limbal relaxing incisions, allowing more patients to be candidates for these Multifocal IOL’s. For patients with moderate to high astigmatism, the Toric lens delivers clear distance vision with less dependence on prescription glasses; near and intermediate vision will still require glasses. Accurate positioning of these Toric IOL’s for optimal visual performance has been aided by perfecting all aspects of the circular opening made with the LenSx Laser.

Is Your Vision Interfering With Your Daily Activities?

Is your vision cloudy?

If so, you may have cataracts. If you are exploring treatment options, the TECNIS Symfony® IOL may be the right choice for you. TECNIS Symfony® IOL is the first and only Extended Depth of Focus (EDOF) presbyopia-correcting IOL that provides continuous, high quality vision at any distance.

Dr. Rosenbaum proudly has this technology in his Lansing, Michigan office which he’s pleased to offer to his patients.

“When the last prescription only helped for a couple of months, I knew I had to do something. I wanted the latest technology. Now I can see lines more sharply. I see colors more vividly.”

- TECNIS Symfony® IOL Patient

TECNIS Symfony® IOL is the first lens of its kind to combine two unique technologies for outstanding visual performance:

Elongating the focus of the eye to provide continuous, high-quality vision.

Corrects chromatic aberration (color distortion) to provide sharp vision in all lighting conditions.

Seamless Vision You Can Rely On

MONOFOCAL IOLs

Monofocal IOLs are used to restore vision for one area of focus – usually distance. Glasses may still be needed for near and intermediate distance activities.

EXTENDED DEPTH OF FOCUS IOL

Extended depth of focus IOL provides a continuous range of high-quality vision – from near to far and points in between – and may reduce the frequency of wearing glasses.

Additional Intraocular Lens (IOLs)

Monofocal IOLs 

are the traditional lenses used for cataract surgery.  This type of lens is very effective at restoring functional distance vision.  They have one point of focus.  While distance vision is improved, most patients still need to wear glasses for other distances, like reading and computer work.  Monofocal IOLs don’t correct astigmatism, so people who have astigmatism may still need to wear distance glasses.

Multifocal IOL 

is a “deluxe” type of lens designed to replace cataracts and help correct more than one point of focus.  Their goal is to correct distance vision and other ranges, like reading or intermediate, to give you greater independence from glasses.  This lens may not be recommended for patients with astigmatism.  Most insurance companies will pay a small portion of this IOL.

Accommodating IOL 

is a “deluxe” type of lens designed to mimic the eye’s natural process of accommodation.  Accommodation is the eye’s natural ability to bend its lens to focus. The eye naturally loses its accommodating power as it ages due to the hardening of the natural lens.  This makes it necessary to wear reading glasses or bifocals.  The accommodating IOL helps restore the ability to accommodate and reduces dependence on glasses.  Most insurance companies will pay a small portion of this IOL.

Toric IOL 

is a lens designed to correct astigmatism.  Astigmatism is when the surface of the cornea has both flatter and steeper curves, similar to the shape of a football .  When the cornea has an uneven curvature, vision becomes distorted.  In order to correct this distortion, correction has to be placed in your glasses or contact lenses.   If you need cataract surgery and have astigmatism, you may want to consider a Toric IOL to help correct the astigmatism to give you the best possible quality of vision after surgery.  While distance vision is improved, most patients still need to wear glasses for other distances, like reading and computer work.  Most insurance companies will pay a small portion of this IOL.
