In brief: LASIK in dry eye

After lasik surgery, dryness can worsen for a few months and slow visual recovery.
If dry eye are present preoperatively, it should be treated before surgery. Unless the dry eye is severe, most patients can be treated for the dryness and can proceed with lasik surgery.

In brief: Worse dry eyes

Lasik has known risk factors including causing or worsening dry eyes.
The creation of the flap as well as the laser process disrupts the normal corneal nerves which are part of the sensory pathway for the eye to sense dryness and make tears. After lasik the eyes cannot sense the dryness as well (for a short while) until the nerves grow back. In some patients, the nerves may not grow back well.

In brief: LASIK adds dryness

One of the major complications of lasik is the production of eye dryness.
This is screened for pre-operatively but some probably with borderline dryness or extra sensitivity get "pushed over" into dryness which can be quite bothersome. If you already have symptomatic dryness, then lasik potentially could worsen it and maybe even threaten the vision.
