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 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.
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.
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.
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.
