The contact lens after PRK -- is there possibility that it will move out of place within that 1 week of healing ?!

Dislocation of the bandage lens placed after prk surgery is rare. If it happens it should not be a cause for concern. The lens helps in the healing process and reduces discomfort. Under the unusual circumstance that it moves out of place or falls out of the eye healing will still progress. Your surgeon can replace the lens as necessary.
