Is LASIK safe?

Simply put, safety is the number one priority during every LASIK procedure. The procedure is short. Many people notice a change to their vision almost immediately.


Maybe that’s why hundreds of thousands of Americans opt for LASIK to change the way they view the world every year.1 It may also be why 98.4% of patients said they would get CONTOURA® Vision again.*,†,2

Does LASIK hurt?

The majority of LASIK patients feel little or no pain at all during the procedure. However, keep in mind that there is no guaranteed level of comfort for a LASIK procedure.


Be sure to discuss the risks and benefits of WaveLight® LASIK technology and CONTOURA® Vision with your doctor so you can make an informed decision that’s best for you. You may just be pleasantly surprised by what you learn.

LASIK risks

Although most people do not experience serious LASIK complications, the procedure may result in dry eyes; the possible need for glasses or contacts after the procedure; visual symptoms including halos, glare, starbursts and double vision; and loss of vision.1 While the risks of these visual symptoms exist, keep in mind that LASIK complications are rare events.1


Discussing the risks of a LASIK procedure with your doctor is one of the best ways for you to evaluate whether or not the procedure is right for you.

Why doctors believe in WaveLight® LASIK technology with CONTOURA® Vision

“A lot of times, even people who have very normal eyes and 20/20 vision will have asymmetry in their astigmatism or they’ll have little bumps and valleys that make their vision less than perfect even when they have contacts or glasses. The only technology in the world that can correct both types of defects is topography-guided [LASIK].”

“It’s a way of measuring the whole profile of the surface of the eye — the surface of the cornea. This innovative procedure can address very fine details, small irregularities and astigmatisms. These are things we can’t fully correct with glasses. By doing a customized laser vision correction, we can try to correct the patient’s prescription and their refraction. The astigmatism and myopia that they may have can be corrected but also those small details as well.”

— Ronald Krueger, MD,** Cleveland Clinic Cole Eye Institute, Cleveland, OH

“We’ve done a very careful clinical trial to study topography-guided LASIK. It measures the refractive status of the eye and the curvature of the cornea, and corrects both. The outcomes that we see are superior to those that we’ve been accustomed to seeing with previous technologies. Therefore, it gives us the opportunity to offer something to our patients that we were not able to offer to them before. We have the opportunity to provide them with vision that is quite often better than glasses and contact lenses.”

“Is this going to be the first-line treatment? I think the answer is ‘yes.’ The only thing that would preclude [most myopic or astigmatic patients] from being a candidate is if we cannot get good topography, meaning we can’t get a good image on the topographer. How often does that happen? That’s pretty rare. So I think it’s going to be applicable to probably 90% [or more] of my myopic, astigmatic patients. It’ll be my first line of treatment.”

*Study description: Prospective, nonrandomized, multicenter study of 249 eyes with myopia (up to -9 D) or myopic astigmatism of 6.0 D or less. Outcome measures included manifest refraction, UDVA, CDVA and visual symptoms up to 12 months.
