In order to make the right decision concerning your eyes, the time to ask “what is laser eye surgery and how will it affect me?” is before you decide to have the procedure.
The cornea is the most important part of the eye. It helps to focus and bend the light so that you can accurately see what’s in front of you. In perfect formed corneas, the person will have 20/20 vision. However, if the shape of the cornea is not perfect, the bending of the light will not be as accurate, resulting in vision that is out of focus or blurry. What laser eye surgery does is to reshape the cornea to the shape necessary for you to see objects clearly.
In the early days of refractive surgery, this reshaping of the cornea was done with scalpels. As laser techniques progressed they soon took over as they allowed the physician to make more precise cuts than a scalpel.
Laser eye surgery is primarily used for three types of vision problems – near sightedness, farsightedness, and astigmatism. In these cases, laser eye surgery can reshape the cornea thus enhancing its focusing power.
What Cautions Are Necessary for Laser Eye Surgery?
The first and most important decision to make if you decide to have laser eye surgery is choosing your physician. The greater the number of successful laser eye surgeries a doctor has performed, the greater the odds shift in your favor for a successful outcome. Therefore, choose a doctor who has performed hundreds of surgeries.
Secondly, not all lasers are equal. You want to be sure of is that the laser your doctor is using is one that has been approved by the Food and Drug Administration. Don’t assume – ask your doctor to be sure.
There are a couple of different types of laser eye surgery that are currently popular – LASIK and Precision.
Originally LASIK was used only for those who are suffering from nearsightedness. Today, however, it can also treat those who are farsighted or have astigmatism. LASIK often has a faster recovery period and vision has noticeable improvements immediately following treatment.
Precisioin sugery is typically done as an outpatient care with eye drops that have local anesthesia. A refractive correction is used with a computer controlled laser beam to reshape the cornea. The recovery period for this procedure is usually about three days. There is no guarantee that this procedure will completely eliminate your need for corrective lenses. Some side effects include seeing a glare or halo around lights but they will often disappear eventually. So now you can also see that the answer to what is laser eye surgery is that it allows individuals to make the decision to improve their quality of life.
Lasik surgery is a bit more than 11 years old. Precision surgery has been around maybe a year or two longer. LASIK surgery is considered more invasive and the skill of the doctor is more important in LASIK surgery than with Precision surgery. One is not necessarily better than the other, it all depends on the particular patient.
Before you choose either LASIK or Precisoin surgery, consult with your ophthalmologist who can recommend to you the best option for your particular circumstance.
