Hazy Days – How Lasik Clears Up Those Days.
Many people depend on wearing glasses or contacts everyday. Glasses and contacts can be a hassle though, especially for active people on the go. With Lasik vision correction surgery, losing contact lenses or forgetting where you put your eyeglasses can be a thing of the past. For most people who have Lasik surgery, vision is greatly improved reducing or completely eliminating the need for corrective lenses.
There is always new technology with Lasik procedures. There are several types of Lasik procedures that can successfully be used on a patient. The type of procedure that you will have will depend on what your Lasik doctor prefers and what works best for your eyes. WAVEFRONT Lasik is the most commonly used Lasik procedure. There are also procedures called diagnostic workstation and Orbscan technology.
In general, Lasik is performed to restore vision and the results are immediate. A surgical instrument called a microkreatome is used during the procedure to create a thin, circular flap in the cornea. This flap can also be created using a laser, which is usually more precise and has a higher success rate.
After the flap on the cornea has been cut, the doctor folds the flap out of the way and removes some of the corneal tissue. This is done using what is called an eximer laser. This laser uses cool ultraviolet light beams to remove very small pieces of the tissue. After the tissue is removed, the cornea is reshaped causing it to work better focusing light into the eye and onto the retina. This results in the patient immediately having better, clearer vision that before the procedure. The flap is put back in place to cover the area where the tissue was removed.
The Lasik surgery is both a quick and relatively painless procedure for most patients. During the surgery, patients remain awake and are able to walk out after the procedure. The procedure is also painless because the surgeon will give the patient eye drops that anesthetize the eye before the surgery begins. Some patients who are uncomfortable about the procedure can be given a mild sedative before the procedure begins. Before the procedure begins, the patient will lie down and the doctor will place a special device to keep the eyelids open during the surgery. Also, this device has a suction ring on it to keep the eye pressurized. Once the surgery begins, it only takes about one minute for the whole procedure to take place.
If your doctor uses a laser during your procedure, the computer is adjusted so that the laser can remove the right amount of corneal tissue. While the procedure is painless and quick, you might hear the clicking sound of the laser and be able to smell a slightly acidic order. This is caused by the tissue removal. The surgeon has complete control of the laser and it can be stopped at any time during the procedure. If you choose to have both eyes done, the doctor might choose to wait for a little while before operating on the next eye. Some patients prefer to have the second eye done a week or more after the initial procedure.
WAVEFRONT is generally considered the most trusted procedure and is though to produce the best results. This procedure is popular because as a general rule, WAVEFRONT can be customized to treat your eyes. This gives much better results to the patient. Also, with this technique, some patients have better vision, sometimes 20/15 after having WAVEFRONT Lasik. In a study comparing WAVEFRONT to the conventional Lasik procedure, 90 to 94 percent of all patients had 20/20 vision or better after the procedure. This is compared to 80 percent of patients that achieve 20/20 vision with the conventional method. Also, many doctors prefer the WAVEFRONT procedure. This is because this procedure decreases the risk of complications such as haloes or night glare
The diagnostic workstation technology has advantages because it can cover a much larger area since the pupil can dilate up to twice the normal size. The Orbscan technology also has its advantages. It can determine without a doubt if you are a good candidate for this procedure. The Orbscan has the ability to be more accurate diagnosis and treatment of vision problems.
