Concerns after LASIK

It has been about five years since I had LASIK. Since changing jobs last year, I have been under a lot of stress, especially due to the heavy computer work. I noticed my vision in my right eye deteriorating significantly, so I got blue light glasses fitted and always wear them while working. Lately, however, I feel a foreign body sensation in my right eye, and it stings and feels uncomfortable. Does anyone know if re-surgery is possible after LASIK? I should have taken better care of my eyes, and now I am regretting it belatedly.
