I am 9 months post lasik with moderate dry eyes. I'm past the typical 6month healing marker. Will my eyes continue to heal?

No. Your eyes are completely healed from the lasik procedure. If you have dry eyes, you will need to treat them. Consult with your ophthalmologist for treatment options.
May. Your dry may get better with time or may stay the same. Please make sure to optimize your tear film with the artificial tears, lid hygiene (using heat pack over the lids and baby shampoo wash the lashes), omega3 intake. If your dry eye persist then you may need punctal plagues to close your tear drainage and medication (restasis). Please consult with your eye doc.
