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.
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.
The patient should note an almost immediate improvement in his or her vision, as early as the day after surgery. A new glasses prescription will be provided to the patient, and after a month, the full extent of the improvement should be realized. Following the doctor's orders where the use of any prescribed medications is concerned, is essential to obtaining optimal results.
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.
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.
