Finding a Surgeon
Only ophthalmologists (Eye MDs) are permitted to perform Lasik. Ask your Eye MD or optometrist for a referral to an Eye MD who performs Lasik. The American Academy of Ophthalmology website www.eyenet.orgfeature “Find an Eye MD” can provide you with a list of their members who perform Lasik. Ninety-five percent of all ophthalmologists (Eye MDs) are Academy members. Also, the International Society of Refractive Surgery website www.LocateAnEyeDoc.com will provide you with names of refractive surgeons.

Ask your surgeon the following questions:

  • How long have you been doing Lasik surgery?
  • How much experience do you have with the Lasik procedure?
  • How do you define success?
  • What’s your success rate?
  • What is the chance for me (with my correction) to achieve 20/20?
  • How many of your patients have achieved 20/20 or 20/40 vision?
  • How many patients return for enhancements?
  • What laser will you be using for my surgery?

Make sure your surgeon is using a laser approved by the U.S. Food and Drug Administration (FDA). As of this publication’s printing, the FDA has approved five lasers for Lasik; they are manufactured by VISX, Summit, Bausch and Lomb, Nidek and ATC. Contact the FDA for updates.

  • Who will handle after-surgery care? Who will be responsible?
  • What about risks and possible complications?

Risks and Possible Complications
Before the surgery, your surgeon should explain to you the risks and possible complications, and potential side effects, including the pros and cons of having one or both eyes done on the same day. This is the “informed consent” process. Some risks and possible complications include:

  • Over- or under-correction. These problems can often be improved with glasses, contact lenses and enhancements.
  • Corneal scarring, irregular astigmatism (permanent warping of the cornea), and an inability to wear contact lenses.
  • Corneal infection.
  • “Loss of best corrected visual acuity” - that is, you would not be able to see as well after surgery, even with glasses or contacts, as you did with glasses or contacts before surgery.
  • A decrease in contrast sensitivity, “crispness,” or sharpness. That means that even though you may have 20/20 vision, objects may appear fuzzy or grayish.
  • Problems with night driving that may require glasses.

Flap problems, including: irregular flaps, incomplete flaps, flaps cut off entirely, and ingrowth of cells under the flap.
The following side effects are possible, but usually disappear over time. In rare situations, they may be permanent.

  • Discomfort or pain
  • Hazy or blurry vision
  • Scratchiness
  • Dryness
  • Glare
  • Haloes or starbursts around lights
  • Light sensitivity
  • Small pink or red patches on the white of the eye

Surgery: What to Expect Before, During and After

Before…

You’ll need a complete eye examination by your refractive surgeon. A preliminary eye exam may be performed by a referring doctor (Eye MD or optometrist). Take your eye prescription records with you to the exams. Your doctor should:

  • Dilate your pupils to fine-tune your prescription.
  • Examine your eyes to make sure they’re healthy. This includes a glaucoma test and a retina exam.
  • Take the following measurements:
    • The curvature of your cornea and your pupils. You may be rejected if your pupils are too large.
    • The topography of your eyes to make sure you don’t have an irregular astigmatism or a cone-shaped cornea - a condition called Keratoconus.
    • The pachymetry - or thickness - of your cornea. You need to have enough tissue left after your corneas have been cut and reshaped.
    • Ask you to sign an informed consent form after a thorough discussion of the risks, benefits, alternative options and possible complications. Review the form carefully. Don’t sign until you understand everything in the form.

If your doctor doesn’t think Lasik is right for you, you might consider getting a second opinion; however, if the opinion is the same, believe it.

If you qualify for surgery, your doctor may tell you to stop wearing your contact lenses for a while before the surgery is scheduled because contacts can temporarily change the shape of the cornea. Your cornea should be in its natural shape the day of surgery. Your doctor also may tell you to stop wearing makeup, lotions or perfume for a few days before surgery. These products can interfere with the laser treatment or increase the risk of infection after surgery.

During…
Lasik is an outpatient surgical procedure. The only anesthetic is an eye drop that numbs the surface of the eye. The surgery takes 10 to15 minutes for each eye. Sometimes, both eyes are done during the same procedure; but sometimes, surgeons wait to see the result of the first eye before doing the second eye.

The Surgical Procedure: A special device cuts a hinged flap of thin corneal tissue off the outer layer of the eyeball (cornea) and the flap is lifted out of the way. The laser reshapes the underlying corneal tissue, and the surgeon replaces the flap, which quickly adheres to the eyeball. There are no stitches. A shield - either clear plastic or perforated metal - is placed over the eye to protect the flap.

After…
Healing is relatively fast, but you may want to take a few days off after the surgery. Be aware that:

You may experience a mild burning or sensation for a few hours after surgery. Do not rub your eye(s). Your doctor can prescribe a painkiller, if necessary, to ease the discomfort.

Your vision probably will be blurry the day of surgery, but it will improve considerably by the next day when you return for a follow-up exam.

If you experience aggravating or unusual side effects, report them to your doctor immediately.

Do not drive until your vision has improved enough to safely do so.

Avoid swimming, hot tubs and whirlpools for two weeks after surgery.

Alternatives to Lasik
You may want to discuss some surgical alternatives to Lasik with your eye doctor:

  • Photorefractive keratectomy (PRK) is a laser procedure used to reduce myopia, hyperopia and astigmatism without creating a corneal flap.
  • Astigmatic keratotomy (AK) is an incisional procedure to reduce astigmatism.
  • Intrastromal corneal rings are clear, thin, polymer inlays placed on the eye to correct low myopia only.
