Healing and expectations with PRK
Keep your eyes moisturized as much as possible, for the first few days post op, keep them closed as much as possible. Listen to some podcasts or books on tape.
Take some extra vitamin C- it can aid in collagen healing.
If they give you "pain drops" attempt not to take them, it slows the healing.
Put a cold pack on to limit swelling. Its normal for your lids to be puffy and even the white part of your eye to have swelling which makes it even more uncomfortable, so get the cold pack on right away and have your husband replace it often.
Be patient with the vision. I had pretty bad erosions on my cornea after LASIK and I saw triple images for 2-3 weeks.
