It sounds like you are experiencing significant dryness in your eyes. Are you using preservative free artificial tears every hour? If you are, your doctor may suggest starting a thicker gel-like preservative free drop, lubricating ointment for use at bedtime, punctal plugs, or restasis. Dryness commonly causes the eye to feel irritated and may affect vision since the tear film is not stabilized. I recommend that you go back to see your doctor to ask about the other solutions listed above.
