Heller says Paterson was evaluated at Mount Sinai Medical Center, where he learned that pressure in his left eye had increased, causing the pain. The governor also has a cataract in his left eye.
After the procedure to relieve the buildup of fluid pressure, Paterson left to attend his son's graduation and serve as commencement speaker.
Heller says he'll return to the doctor's office for a follow-up visit to ensure the procedure was successful.
