What are the advantages of LASIK?

LASIK has many benefits, including:

  • It works. It corrects refractive error. About 95% of patients are satisfied with the outcome of LASIK (based on a government-sponsored, patient-reported outcomes study).
  • LASIK surgery is associated with very little pain.
  • Vision is corrected nearly immediately or by the next day after LASIK.
  • Recovery is quick. Usually, no bandages or stitches are needed after LASIK.
  • Adjustments can be made years after LASIK to correct vision even further.
  • After having LASIK, most patients no longer need corrective eyewear (glasses, contacts, etc.).

What are the disadvantages of LASIK?

  • Changes that are made to the cornea cannot be reversed after LASIK.
  • LASIK is generally not covered by insurance plans, and is paid for by the patient.
  • LASIK eye surgery is technically complex. Problems can occur when the doctor creates the flap, which can permanently affect vision. The use of femtosecond lasers has reduced this risk.
  • Rarely, complications related to LASIK laser eye surgery can cause a reduction in the best vision achievable with or without glasses.
