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.
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".
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.
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.
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.
Most patients will experience improved vision as early as the day after the operation. New eyeglasses will be prescribed and once about a month has passed since the surgery, the maximum degree of improvement will be apparent. It is important for the patient to use all medications the doctor prescribes in order to ensure the best outcome 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.
