My right eye constantly feels like there is something in it 2 weeks after LASIK. Will this feeling go away?

You are most likely experiencing dryness as its only been 2 weeks. The tear drops do not last long unless you are using the gel drops so you will need to stay consistent with them. Avoid conditioned air blowing directly at your face such as in the car as this air is low in humidity and will dry you out very fast. If you are staring at the computer alot for work remember to blink as this is what initiates tear production. Drink lots of water too. Dryness is a known side effect of Lasik so it shouldn't worry you too much as long as it does not persist.

Dryness is common in the early stages of healing after LASIK. When eyes are dry, it can feel like something is in there. You can try preservative free tears every 1-2 hours to alleviate the sensation. If it still feels uncomfortable, please see your doctor to ensure that you are healing properly. 

Foreign Body Sensation after LASIK usually gets better.I tend not to see it for those you start tears 4 times a day before the surgery.Sometimes the post operative drops can be a cause but don't stop them without consulting your surgeon and showing them the bottles.Unfrozen Autologous Serum works wonders quickly for tough cases.Best of luck to you.
