Little Eye pain and irritation.

I'm feeling little pain and irritation in the eye. I underwent LASIK treatment in 2016. 3 months back I felt pain from right eye to right ear. I consulted eye doctor and I explained him about my issue and said that I use laptop at least 5 hours a day. He said it's computer vision syndrome and he prescribed Systane Ultra eye drops. But didn't relieve any pain or irritation. 1 month back, I consulted ear doctor and explained about my pain from eye to ear. He said it's common to get eye pain during ear pain and prescribed tablets. I used them and I got relieved from ear pain. But pain and irritation in the eye is still there. Now I'm not using laptop also and if I watch TV, I use anti glare glasses. Which medication should I use to get relieved from this light pain and irritation?
