How Lasik Works

Lasik eye surgery has become more and more popular of late. Most people with vision problems are probably aware by now of the procedure’s potential to correct common eyesight issues such as farsightedness, nearsightedness and astigmatism. As lasik has become increasingly available and more affordable, its rise in popularity should be no surprise as millions of people suffer from poor or declining eyesight. So what is lasik surgery and how does it work?

Laser assisted in situ keratomileusis, more commonly known as LASIK surgery, is a kind of refractive surgery that reshapes the cornea which results in the increased ability of the eye to see. The lasik surgeon uses an instrument called a microkeratome to create a round, very thin flap in the outer tissue of the patient’s cornea. The flap is then folded out of the way while the surgeon uses an excimer laser to reshape and flatten the cornea. Once the patient’s cornea has been reshaped, the flap is replaced. The actual lasik surgery procedure takes roughly fifteen minutes per eye. The patient remains awake throughout the entire duration of the procedure.

While lasik surgery is a very popular option for people with common eyesight problems, the procedure is not for everyone. If you are thinking about having lasik surgery, talk to your eye doctor about it. Your eye doctor will be able to give you a complete and thorough description of each step in the procedure. Lasik centers will often have written materials like brochures, live seminars you can attend or even videos you can watch to learn more about the surgery. In addition, your doctor will be able to determine if you are a good candidate for lasik and discuss the risks and benefits with you as well. Talking to your doctor and asking any questions you have is the best way to stay informed about lasik.
