I was just discussing this very issue with the Allergan representative and no formal studies have been completed. Since Latisse only goes on the lashes, and since even if a small amount made it into the eye it is a safe glaucoma medication (Lumigan), it is not believed that Latisse should be a problem after LASIK.
A better question might be how soon after LASIK can you use Latisse, and this is more difficult to answer. We are telling patients to discontinue Latisse a day prior to LASIK and not to resume it for at least a month to allow the flap to heal without the potential of trauma from the application, and to avoid any possible interference with healing. Our recommendation is that it be on hold for 6 weeks and restarted after the 6 week post op visit. If there are any signs of dry eye at six weeks we might ask them to wait a little longer.
The good news is that it takes Latisse 8-12 weeks to have a maximum benefit, and it takes about that long for the effect to disappear. Therefore, waiting six weeks will not result in a significant loss of the lash enhancement benefit.
