How long has LASIK been performed?: LASIK has been performed internationally for approximately 10 years. It was first performed in clinical trials in the U.S. in 1995. Ophthalmologists have been reshaping the cornea for over 50 years, creating a protective layer of tissue for over 35 years, and using the excimer laser since the 1980s.

Who can LASIK benefit?: LASIK will benefit those patients with near or farsightedness or astigmatism. Candidates should have a strong desire to be less dependent on corrective lenses and willing to accept the risks of surgery.

What results can I expect from LASIK?: At one year after the VISX CustomVue procedure*

  • 100% of the clinical study participants could pass a driving test without glasses or contacts
  • 98% of the clinical study participants could see 20/20 or better without glasses or contacts
  • 70% of the clinical study participants could see 20/16 or better without glasses or contacts

Four times as many clinical study participants were very satisfied with their night vision after the VISX CustomVue procedure, compared to their night vision before with glasses or contacts.

Are the results from LASIK permanent?: The effects of LASIK are permanent. They do not wear off. But it is important to realize that your eyes can still change internally.
If I have LASIK and my vision changes later in life, can it be redone?
Re-treatment may be a solution to changing vision later in life, and other options exist. You need to consult with your doctor to determine which option is best for you.

What type of anesthetic is used for LASIK?: The procedure is done with a topical anesthetic (eye drops) to numb the eye.

Does LASIK hurt?: Because patients are given eye drops to numb the eye, you will experience no pain during the procedure. When the surgeon applies the vacuum ring, the patient experiences a sensation of pressure. The instrument surgeons use to create the flap, and the laser do not cause any pain. For several hours after the procedure, many patients describe a mild burning sensation, such as after opening the eyes while swimming in chlorinated water. After the first few hours, this feeling usually subsides.

Will I need to wear glasses once my eyes have healed?: Most patients do not have to use glasses during their daily life. However, patients over the age of 40 may need to wear glasses for reading. This is caused by the normal aging of the eye that occurs with or without LASIK.
