I underwent lasek eye surgery before 3 weeks and i have blurry vision, is it normal?

Can be: After lasik surgery your eyes will be very dry, because the nerves that tell your tear glands to make tears have been severed. Until these nerves regrow (which they will), you will need artificial eye drops on a regular basis. When i had lasik, my eyes were blurry when i woke because they were dry, but this got better with drops and time. Check with your surgeon too though.

Check with Dr: Vision may heal slowly after prk or lasek. Check with your surgeon to ensure that your healing is on track. Vision after lasik usually returns rapidly, usually a significant amount by the next day.

LASEK : No it's not normal. You may need punctal plugs.
