I provide both sunglasses and sleeping goggles to my Lasik patients and encourage them to wear the sleeping goggles for three nights. I do extend that, in some cases, however. A few examples would be for patients who sleep with their head buried in the pillow, or others who may have young kids that come bounding into their bed at 3AM. In these cases I recommend a week or even longer. The main notion is to protect the eyes from trauma for the first week or two post Lasik and to acknowledge that "Murphys Law" is very much in effect after any surgery. That being said, I have not had a Lasik flap move after surgery in 10 years. I feel the all laser aspect of the surgery is the reason for this. Mechanical creation of the flap(which I don't do any longer) has a higher incidence of flap movement post op. The laser created flaps(thats all I do) are much more stable.
