You might also notice unusual sensitivity to bright light or double vision. 3 Undercorrections: You won't benefit from LASIK if the laser used removes a small tissue from the cornea. This side effect is common in patients with nearsightedness, and a repeat LASIK is done to remove more tissues. 4 Overcorrections: In some situations, the laser may remove excess tissue from the cornea.
