Q: What is LASIK?

LASIK (Laser-Assisted-In-Situ Keratomileusis) is an FDA-approved outpatient procedure that uses the excimer laser to reshape the cornea to correct your vision. LASIK changes the shape of the cornea, the clear covering of the front of the eye, to correct refractive errors of myopia, hyperopia, and astigmatism. LASIK typically takes about 10 minutes to perform on each eye and is one of the most frequently performed healthcare procedures in North America

There are several steps involved in the patient's LASIK experience:

	Immediately prior to your procedure, your eyelids and lashes will be cleaned. A mild sedative may be given. Anesthetic drops are applied to the eye, to completely numb the eye for comfort, and a lid holder is used to keep your eyelid open.
	A protective flap is created and gently lifted by the surgeon. The corneal flap preserves the surface layer of the cornea so discomfort following LASIK procedures is minimized.
	Your surgeon uses information from your comprehensive testing to set a surgical plan that is programmed into the laser. The computer calculates the required treatment and directs the laser.
	Computer-controlled pulses of cool laser light are applied to the inner layers of your cornea. The inner corneal layer is reshaped with the laser to match your contact lens or glasses prescription.
	The surgeon gently replaces the flap and aligns it to its original position. It heals naturally and securely.
