A cataract is when the natural lens of the human eye becomes cloudy or hazy. Usually cataracts develop in the older segment of the population because the lens of the eye is a living structure and also ages.

There are various types of clouding of the lens. When the entire lens becomes yellow-brown in color, the term nuclear sclerotic cataract is used. If spoke-like lines develop, the term cortical cataract is used. When a small patch of haze develops on the central posterior part of the lens, the term posterior subcapsular cataract is used. Various combinations can occur together. Other types of opacities, spots, flecks, and discolorations can occur in the lens, each with its accompanying descriptive term.

Cataracts are not only an isolated problem of the elderly, they can occur in newborns, children, young adults, too. Various insults can cause the formation of cataracts, including x-ray or radiation exposure, ultraviolet light, medicines, toxic chemicals, infections, inflammation, trauma. Birth problems or developmental problems of the eye can lead to cataract formation. Cataracts can cause unique visual difficulties, depending on the type.

a clear lens allow light rays to focusWhen the natural lens is clear light rays pass through it and become focused on the back of the eye.


A clear lens allows clear visionHere is an example of a view of a clock through a clear lens.



A clody lens scatters light raysWhen the natural lens becomes cloudy and hard the light rays become scattered. Much of the focus is lost or distorted, resulting in decreased vision.

Usually a patient may complain that their vision is foggy, blurry, hazy, or smokey. Colors may seem washed out. They may experience glare or halos around bright lights.  Activities of daily living may be more difficult to accomplish such as reading books, labels, instructions, seeing signs, driving, sewing, computer work.

A cloudy lens causes cloudy visionThis is an example of a view of a clock through a cloudy hard lens. Is this happening to you?

Sometimes a cataract may cause other severe vision threatening conditions such as a form of glaucoma.  Cataracts are diagnosed at the time of a complete eye examination. The decision to remove a cataract occurs when the patient’s vision is not adequate enough to safely do activities of daily living and Dr. Gualtieri has made certain no other conditions are responsible for the decreased vision.

Dr. Gualtieri performing cataract surgery 

Today modern "no-stitch" cataract surgery is a reality. Cataracts can be removed on an outpatient basis by a skilled surgeon and microsurgical computer controlled instruments. The surgery time (personally done by Dr. Gualtieri) is about 30 minutes. The entire out-patient surgery block of time is 3 hours because there is a hour before for preparation and an hour after for light recovery & observation. You will go home with a small patch over the eye and returning to normal activities immediately after surgery is possible !

The actual surgery consists of first numbing the eye with topical anesthetic drops. Then a small 3-mm incision is made. Through this incision, an instrument called a phacoemulsification ultrasound probe

The ultrasound probe gently vacuums out the cataractThe probe is a hollow tube, which vibrates with ultrasound and emulsifies and vacuums out the cataract. 

The new implant lens is inserted into the eyeA new flexible clear plastic lens implant is placed though the incision and positioned inside the clear capsule "bag" that remains after the cataract is removed. The incision is self-sealing so stitches are not needed. The patient leaves the operating room with new better vision and new found independence.   The surgery time is about 30 minutes. The entire out-patient surgery block of time is 3 hours because there is a hour before for preparation and an hour after for light recovery & observation. You will go home with a small patch over the eye and return to normal activities as tolerated immediately!

PREPARING FOR CATARACT SURGERY

After the diagnosis of a cataract, the patient should expect the following:

1. A pre-operative visit with Dr. Gualtieri where a brief history and physical exam is performed, special eye measurements are made, the type of IOL is chosen, pre-operative forms and consents are signed, and medications are obtained. We offer an eye kit containing all the necessary medications and supplies to care for the eye after surgery. The out-of pocket cost is $30. An option is prescriptions for you pharmacy and copays for the 4 medicines that could total much more than $30

2. Surgery day. You will usually arrive at the surgery center 1 hour before the surgery to be prepped. You will be dressed in a gown, connected to vital sign monitor, and receive, pre-operative eye drops. Dr. Gualtieri and the anesthesiologist will visit with you before starting the case. The procedure will last about 30 minutes. You will be awake but sleepy and very comfortable. After the operation, you will go to a recovery area for a final check, then home to start your eye medications.
