Before Undergoing Cataract Surgery San Antonio Patients Should Know What To Expect

By Coleen Torres


Patients who suffer from cataracts have difficulty seeing clearly since the normally clear lens of the eye becomes cloudy, preventing light from entering properly. If not treated, the vision will worsen to the point of blindness. Fortunately this condition can be easily corrected with a straightforward surgical procedure. If they wish to learn more about cataract surgery San Antonio TX patients should visit an opthalmologist.

This type of surgery is performed under local anesthetic, and it involves first making a tiny incision on the side of the cornea, often with a laser. Next, a device which generates ultrasonic vibrations is inserted that will cause the diseased lens to break apart into tiny pieces to the point where it is liquified, these particles are then suctioned out. This process is called "phacoemulsification".

The original lens is replaced with an artificial one called an "intraocular lens" which is intended to last indefinitely and does not require any specific measures to maintain it. Intraocular lenses are made out of transparent plastic, acrylic, or silicone materials.

Patients are able to return home an hour or two after the procedure since it is performed on an outpatient basis and generally can be completed in under an hour's time. Most people are awake during the operation but may be given a sedative. The surgeon will only operate on a single eye, so those who require cataract removal in both will need to undergo a second operation several weeks later.

Following the procedure, patients can anticipate some minor discomfort in the eye, and it may also water more readily and be sensitive to sunlight. These complaints are easily remedied with analgesics, and sunglasses to provide protection from the sun when outdoors. The doctor will prescribe eye drops to prevent infection, and otherwise just taking it easy for a day after the surgery and not over-exerting oneself is all that's needed for recovery.

Improvement of vision should be noted in the patient the day after surgery. In a month's time of so, he or she will be prescribed new glasses and at this point the full extent of the improvement in eyesight should be apparent. Taking care to use all medications prescribed following surgery is important to obtain the best results possible.

Generally a lens implant is a permanent fixture that will last for the patient's lifetime and will not need to be replaced. Although rarely, there may be clouding of the lining of the lens several months or years after it has been installed. This happens as a result of cell growth in the membrane of the eye which surrounds the synthetic lens.

A simple, painless, in-office procedure called "YAG laser capsulotomy" is used to correct this issue if it occurs. This is carried out with a special laser device that removes the excess cell growth which is clouding the lens, which restores the patient's vision. It only takes a few seconds to do this procedure. A cataract cannot grow back once an intra-ocular lens is implanted however.
