While this technological innovation gets high praises, you must still do your homework and learn about it before you undergo the procedure. Experts from Del Negro & Senft Eye Associates list the things you need to know about LASIK:

Before surgery

Laser vision correction is a procedure proven effective for specific problems such as astigmatism, nearsightedness (myopia), and farsightedness (hyperopia). An ophthalmologist will not refer patients with substantial refractive errors.

Meticulous screening is very important, so rely on the recommendation of experienced doctors. If you are a suitable candidate, the surgeon will prepare you for the procedure, and you must pay attention to the guidelines to lower the risk of infection and other complications.

During surgery

The third option in the management of vision problems after eyeglasses and contact lenses is Laser Vision Correction. A qualified surgeon performs the elective procedure, which involves an excimer laser. The light beam is .25 microns wide, or 0.5% of the width of a strand of your hair. The surgeon reshapes the cornea to correct vision problems. Be prepared to receive medication for relaxation if the doctor thinks this is advisable.

After surgery

Usually, after the procedure, patients notice an improvement in their vision. Technological improvements make current equipment safer and more reliable, reducing the risk for complications markedly. Since your eyes can be sensitive to light after the procedure, you must be protective. Apply prescribed steroid and antibiotic drops. Healing should not take too long if you have good general health.

The excimer laser was developed in 1970, and now it is making it possible for people to see better and participate more effectively and safely in daily life.
