What is a cataract?


(cat·a·ract) A cataract is the clouding of the crystalline lens in your eye. This opacity obstructs the passage of light resulting in a reduction of clear vision. Normally, light passes through the clear lens and is focused onto the Retina. However, the natural aging process can cause the lens to become cloudy, or milky. The cataract blocks the passage of light through the eye and causes distorted or blurred vision, glare, or difficulty seeing in poor lighting conditions.

There are three types of cataracts:

A nuclear cataract forms in the lens center. Those over 65 are more prone to develop this type of cataract as more than half of all Americans over the age of 65 will develop a cataract.

A cortical cataract forms in the lens, then grows from the outside to the center of the lens. Diabetics are more prone to develop this type of cataract.

A subcapsular cataract forms in the back of the lens. Those with diabetes, high hyperopia (Far-sightedness) or retinitis pigmentosa may be at a higher risk to develop this type of cataract.

 

What are the symptoms?


You may not notice a slight change in your vision, as cataract starts out very tiny, but as it grows from the size of a pin head, you may notice that your vision is becoming blurry, and you may feel as if you are looking through dirty eyeglasses. Object edges may appear to fade into one another and colors may not appear as bright as they should.

The most common symptoms of a cataract are:

Cloudy or blurry vision.

Problems with light, such as headlights that seem too bright, glare from lamps or very bright sunlight.

Colors that seem faded.

Poor night vision.

Double or multiple vision.
 
Frequent changes in glasses or contact lenses.

Optical aids such as eyeglasses or contact lenses are no longer effective.
 

How is a cataract treated?


Cataract surgery is a selective and successful solution to restoring vision when the cataracts seriously impair your vision and affect your daily life. Cataract surgery is the most frequently performed surgery in the United States, with millions of surgeries done each year. Cataract surgery is a routine and relatively painless procedure.

Cataract surgery is generally performed on an out patient basis. You will not need to be hospitalized or put to sleep for for your doctor to perform your surgery. The procedure normally takes less then 15 minutes and you can return home shortly after your procedure. Most people will enjoy improved vision by the day after surgery or within a few days following the procedure.

To begin, your surgeon will administer a light sedative which will relax your nerves and keep you comfortable during the procedure. Anesthetic eye drops will be used to completely numb the eye. The entire procedure is performed through an incision that is smaller the 1/8 or an inch and does not require stitches to heal.

Once the cataract is removed, an intra-ocular lens (IOL) is placed where the cataract lens was removed, to restore your sight. Most patients will not require an eye patch and will not have any discomfort.

Most patients can return to their normal daily routines; including reading, driving, and exercise, the day after surgery.
 

What Causes a Cataract?


It is not completely known why cataracts occur in all instances, but studies on the cause of cataracts will soon teach us on how to more successfully treat and prevent them.

The most commonly known type of cataract is age related.

Ultraviolet light is a known catalyst for the formation of cataracts, so we recommend wearing 100% UV blocking sunglasses which will lessen your exposure over time.

Other studies point to people with diabetes as a higher risk group for cataract development than those who do not suffer from diabetes.

Cigarettes, air pollution, heavy drug usage and severe alcohol consumption may also contribute to your chances of developing cataracts.
 

Can I be too young or old for Cataract Surgery?


Any patient who can undergo a thorough eye examination can undergo surgery if the procedure is performed with a topical anesthetic-drops alone.

 

How soon can I drive after the surgery?


We will require that you have someone drive you home following your procedure. However, you may drive when you feel comfortable enough to drive safely, possibly the next day.

 

Do I have to avoid all activities post-operatively?


No. We typically demonstrate to the patients that they can bend over immediately after surgery, pick up 20-30 pounds, and shower, provided they don't get water into their operative eye. We do ask that they wear an eye shield at bedtime for the first few weeks after surgery so they do not inadvertently rub the eye during sleep. Typical follow-up evaluations are scheduled at 1 day, 1 week, 3 weeks, and 6 weeks, with glasses being prescribed between the 3rd and 6th week visit.

Does Cataract surgery hurt?


The treatment itself is painless. We will place a few numbing drops in your eye(s) to make you more comfortable.

Will I be able to have both eyes treated at the same time?


Surgery can be performed on both eyes on the same day if we conclude you are a good candidate. Should you wish to have one eye done at a time, the doctor will discuss this with you and we can accommodate this as well.

Do you offer payment options?


Our Refractive Surgery Coordinator will be happy to discuss financing information based on your personal needs. Check with your human resources department for any insurance plan or pre-tax dollars options which may help pay for surgery.
