Guide To Cataract Surgery San Antonio Patients Will Find Helpful

By Coleen Torres


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.

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.

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.

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.

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.
