Is LASIK Safe?


LASIK has among the highest safety rates of any medical procedure. The safety and effectiveness of LASIK is proven by an enormous body of scientific evidence gathered by hundreds of academic medical researchers. It is on the basis of this clinical data– one of the largest ever compiled concerning a medical procedure – that LASIK can be considered very safe and effective.

  • More than 300 published, peer-reviewed clinical studies of primary LASIK were conducted over a 10-year period: 1998 – 2008. (Ophthalmology 2009)
  • The safety and effectiveness of LASIK surgery continues to improve, thanks to increasingly sophisticated technology, surgical skill and optimal patient selection.  Today, serious complications are reported in under 1 percent of patients. (


Although LASIK is proven to be a very safe option for vision correction, it is important to understand that LASIK is surgery and, like all surgery, there are risks.

  • For LASIK, risks and complications may include dry eye, glare/halos and double vision, which usually resolve over time or in some cases can be managed with enhancements or subsequent therapy.
    • Dry eye, glare, halos and double vision are common vision symptoms that you may be experiencing as part of your vision before having LASIK. It is important to discuss all of your vision issues with your surgeon prior to LASIK.
  • There is a healing process following the LASIK procedure. During the recovery period, some patients experience some temporary symptoms or postoperative complaints. These usually resolve with time or may require treatment. These are not sight-threatening complications or adverse events.
