Wearing contact lens before LASIK measurement. Should this be a problem?

Contact lenses can warp or alter the shape of the cornea.  For this reason, we like the patients to be out of their contacts for 1-3 days prior to the pre operative evaluation.   For RGP contacts we have the patient out for 4 or more weeks or will put them in a soft lens for several weeks and then have them out of the soft lens for 3 days.   If the measurements vary from visit to visit, we will have the patient out of their contacts until they are stable.  If you are not out of your contacts and your measurements are off, it is more likely that you will need a retreatment or "enhancement" for the best results.

It is extremely important to have accurate measurements of the refractive status of the eye prior to any refractive surgery, in particular corneal shape, curvatures, and other parameters. All of which could be affected by contact lens wear.I always advise my patients to keep soft contact lenses off for 2 weeks and hard ones for one month.Please always seek medical advice directly from your specialist
