Light sensitivity (photophobia) is a classic symptom of dry eye, and is also present with some other corneal problems.
By chance did you have IntraLASIK (where the flap is cut with the IntraLase laser rather than a microkeratome blade)? There is a well-known photophobia syndrome some people experience after IntraLASIK. It usually goes away relatively soon.
Here is a link to a little more information about that syndrome over on LaserMyEye:
