Is there a limit to how much artificial tears (preservative free) you can use in a day after Lasik?

Too Many Artificial Tears after LASIK
As long as they are preservative-free, you cannot overuse artificial tears after LASIK. I tell my patients to put them in at least 4 times per day and any other time their eyes feel uncomfortable or blurry. I also tell them that they can't overuse them but they can run into problems not using them enough.
Artificial Tears After LASIK
Too much or too little artificial tears
The eye itself will not be bothered by excessive drops even if the eyelids were to react in this way. Eye doctors are generally more worried about dryness on the cornea than about too much exposure to the artificial tears on the eyelids.
Most LASIK patients start reducing the amount of artificial tears as they feel less dryness although they are typically instructed to continue on a set regimen for up to 3 months following the surgery.
