If you are a good candidate for LASIK eye surgery, you have probably wondered, how exactly does LASIK work? This is a great question, and you should talk with your doctor about the different options and procedures that are specifically available to you and what you can expect.However, you should also keep in mind that LASIK surgery isn’t viable for all patients and you may need to be open to other options to improve your eyesight.
How the LASIK Eye Surgery Procedure Works
The LASIK procedure involves using a computer-controlled laser to reshape the cornea and correct refractive errors such as nearsightedness, farsightedness and astigmatism. The surgery typically takes less than 30 minutes (about 10 minutes per eye) to perform, and you should plan to have a friend or family member drive you to and from surgery.
The eye surgeon starts by placing a numbing drop in the eye to make the patient more comfortable, then the area around the eye is cleaned. Next, a tool called a lid speculum is used to keep the eyes open during surgery.
Either a mechanical microkeratome (blade device) or laser keratome (laser device) is used to cut or separate a flap of tissue on the cornea. This flap is lifted and folded back. The laser is then used to reshape the cornea by removing or ablating tissue beneath the flap.
The excimer laser used in some LASIK procedures is a cool, ultraviolet beam that severs the bonds that hold the tissue together. As this tissue is vaporized, the shape of the cornea is altered. The amount of tissue removed depends on the patient’s eyeglass or contact lens prescription, which is essentially etched into the cornea by the laser.
Reshaping the cornea allows light to focus more precisely on the retina for improved vision. The corneal flap is replaced, requiring no stitches. However, a protective shield will be placed over the eye to keep the flap in place until healing is underway. Patients can expect hazy or blurry vision and some discomfort or mild pain after surgery. Other side effects may result from a LASIK procedure.

LASIK recovery varies from patient to patient. Talk with your surgeon prior to surgery about the risks and side effects you can expect, and be sure to contact him or her immediately if any extreme discomfort or vision loss occurs. Regular follow up visits to monitor your vision are necessary for LASIK eye surgery patients.
