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.
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".
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.
It is normal to experience a bit of discomfort afterwards, and the eye may water easily and be more sensitive to the sun. Pain is usually mild and won't last long, easily controlled with over-the-counter analgesics, and wearing sunglasses will be helpful when outside in the sun. Just a day of rest with no strenuous activity is really all that's needed to recover, and eye drops will be prescribed to help prevent infection.
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.
Lens implants are permanent fixtures which should not need to be replaced and are designed to last for the lifetime of the patient. Although it is possible in some people who undergo the procedure, for the cells in the surrounding ocular membrane to affect the function of the new lens. This typically happens several months or just over a year after surgery.
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.
