Lasik surgery is very popular type of vision correction. It was introduced in the 1990s and has gained a staunch following. Since then, millions of people have had their vision corrected by Lasik surgery. Here is some information about Lasik surgery.
There are several different types of vision problems that can be corrected by Lasik surgery. Nearsightedness is caused by a cornea that is too steep. Lasik surgery helps to flatten this problem. Far sightedness individuals have a cornea that needs to be steeper. The other common eye problem that can be corrected using Lasik surgery is astigmatism.
Lasik surgery works by using laser tool to make a round incision in your cornea. This incision creates a flap. Underneath the flap the doctor will do the necessary correction. The flap will then be replaced and reconnected. The entire procedure will only take approximately fifteen minutes per eye to complete.
Recovery time for LASIK surgery is very short and relatively painless. It is an outpatient surgery, and you should be in and out of your doctor’s office in about an hour’s time. Although you should not drive yourself home or operate a vehicle the day of the procedure, within a day or two, your vision should clear and you can resume normal activities. There should be only mild discomfort for a day or two. Most people report it feeling like there is a grain of sand or speck of dust in their eye.
Lasik surgery has a very good success rate. There are only a small percentage of patients whose vision is worsened. These people comprise less than one percent of all Lasik surgeries performed. Many people report dry eye or light around the edge of their vision. These symptoms should fade over time. There are four main types of Lasik surgery. The first is the original type of laser eye surgery called PRK. This type of Lasik surgery lifts the flap and scrapes off some of the offending cells. This is not as common now as other types.
The next Lasik surgery is called E-LASIK or Lasek. This is more delicate surgery and uses a finer blade. It is ideal for patients with mild to moderate short sightedness and who have corneas that are too delicate for traditional surgery. The third type of laser surgery is called EPI-LASIK. EPI-LASIK surgery is also for people whose cornea are too thin for regular Lasik surgery. A flap is not cut in the cornea as with the others. Instead a special instrument is used to get under the cornea so that the laser can do its work. The final type is normal Lasik surgery that is used primarily for patients who are very near or far sighted.
