I had lasik surgery plus cross linking done 25 days ago. OD: -12.00 OS: -11.00. After surgery results were: OD: 20/25. OS: 20/25. OU: 20/20. My concern now is I have dull pain behind my right eye. And I have a constant headache on my right side of the head. My right eye feels drier than my left. I also feel nauseous at times. I feel some discomfort on my right eye as well.
