A cataract is a disorder of the eye characterized by the clouding of the normally clear lens. This usually occurs as a result of aging, but it can sometimes be caused by an injury as well, if left untreated, the patient will eventually be unable to see with the affected eye. Surgery is used to correct this condition effectively. If interested in the prospect of cataract surgery San Antonio TX patients must discuss it with their opthalmologist.
This procedure is termed a "phacoemulsification" and is usually done with a local anesthetic. A surgical laser is used to make a small incision in the side of the cornea in order that an ultrasound device can be inserted which will emit vibrations that cause the diseased lens to disintegrate into tiny particles which are then suctioned out of the site.
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.
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.
