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.
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.
A synthetic lens, known as an "intraocular lens" is implanted in place of the original one. These are designed to direct light onto the retina much like a natural lens does, and are made from clear acrylic, plastic, or silicone. Once installed they are meant to be permanent and don't need any special care to maintain them.
A cataract operation is typically an outpatient procedure, and the patient can return home shortly after. It is normally completed in less than an hour, and in most instances the patient remains awake but sedated throughout the procedure. Surgeons prefer to only operate on one eye at a time, so if the patient has cataracts in both eyes, two surgeries will be needed, usually several weeks apart.
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.
If a patient is found to be experiencing membrane overgrowth that is clouding the surface of the intraocular lens implant, the opthalmologist will perform and quick and painless procedure called a "YAG laser capsulotomy". This can be performed in the doctor's office and effectively restores normal eyesight immediately. The thing about cataracts is that they cannot grow back on an artificial lens, so there is no need to be concerned about that happening.
