LASIK Surgery Safety: Frequently Asked Questions

  • Is LASIK safe?

    Just the thought of a laser pointed at your eye can seem a bit scary! Although all surgery – even LASIK – has risks, but most people who undergo LASIK treatment do not suffer from serious side effects. The most common risks of LASIK surgery include dry eye syndrome; the possible need for glasses or contact lenses after surgery; visual symptoms including halos, glare, starbursts, and double vision; and loss of vision. Be sure to talk with your doctor about the risks and benefits of LASIK surgery before you decide whether it is the right option for you.

  • Will LASIK affect my night vision?

    Some patients experience difficulty seeing at night or glare with very bright light. In most cases, these conditions are temporary and will disappear once the eyes have fully healed.

  • Will LASIK wear off?

    The effects of LASIK are permanent and will not wear off. One of the largest and longest follow-ups of LASIK patients showed that only 20 percent with low to moderate nearsightedness needed retreatment over a 10-year period.1 It is important to realize, however, that your natural lens inside your eye can still change, especially with aging, and this can impact your vision—this is called presbyopia.

Important Information About the WaveLight® Excimer Lasers

WaveLight® Excimer Lasers are prescription medical devices that are approved for use in performing laser-assisted in situ keratomileusis (LASIK) to correct certain kinds of nearsighted (myopia), farsighted (hyperopia), and astigmatism. Only doctors who have been trained in laser refractive surgery (including laser calibration and operation) should use an WaveLight® Excimer Laser.

You should not undergo LASIK surgery if you are pregnant or nursing; if you have a collagen vascular, autoimmune or immunodeficiency disease; if you show signs of keratoconus or any other condition that causes a thinning of your cornea; or if you are taking isotretinoin (Accutane*) or amiodarone hydrochloride (Cordarone*). The most common risks of LASIK vision correction surgery with refractive lasers include dry eye syndrome; the possible need for glasses or contact lenses after surgery; visual symptoms including halos, glare, starbursts, and double vision; and loss of vision.

Talk to your doctor and review the appropriate WaveLight® Excimer Laser Patient Information Booklet for your condition to learn more about the potential risks and benefits for laser refractive surgery.
