The lens of the eye is normally a transparent structure, however sometimes due to aging or injury, it can become clouded, this is referred to as a "cataract". This condition can lead to impaired vision and possibly blindness if untreated. Fortunately, it can be corrected in most cases with an operation. When considering cataract surgery San Antonio TX patients should first find out what's involved in it.
After the patient is given a local anesthetic, the surgeon will make a tiny incision on the lateral part of the cornea using a laser instrument. Then a device which produces ultrasonic vibrations is inserted in the incision, which causes the diseased lens to disintegrate into small particles which are vacuumed out of the eye. The procedure is known as "phacoemulsification".
In place of the lens, an artificial one is implanted. This type of lens is called an "intraocular lens" and it may be made from transparent plastic, silicone, or acrylic, and it requires no special care once it's in place. It serves exactly the same purpose as the original lens, to direct light onto the retina.
Cataract surgery is an outpatient procedure which usually takes less than an hour, and the patient can return home the same day. Most patients remain conscious while it is being done, as they are give a local anesthetic and sometimes a sedative as well. The surgeon will not operate on both eyes at the same time, so those with two cataracts will need to return several weeks later for a second operation.
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.
Most patients will experience improved vision as early as the day after the operation. New eyeglasses will be prescribed and once about a month has passed since the surgery, the maximum degree of improvement will be apparent. It is important for the patient to use all medications the doctor prescribes in order to ensure the best outcome 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.
Patients who are experiencing this complication, will undergo a quick and painless procedure known as a "YAG laser capsulotomy". This can be done in the opthalmologist's office and only takes a few seconds. A laser is used to remove the obstructive cell growth, allowing the patient to once again see clearly. Cataracts will never regrow however, since they can only form on a natural lens surface.
