Is it normal to have double vision after a lasik consultation?

No. You could be experiencing temporary ghosting of your vision from the dilation.
Maybe. During a lasik evaluation, your eyes are dilated with some powerful drops which may affect focus and eye alignment. If the effect doesn't resolve in a day, call your eye doctor.
Double vision. The double vision is likely due to the pupil dilation. It should resolve as the eyes return into normal.
