One of the things that I researched prior to surgery were how to deal with the potential deficits. I was extremely nearsighted and couldn't deal with the thought of not being able to wear contacts. I went and had Lasik prior to surgery and was extremely pleased. It gave me comfort going into my AN surgery that I could deal with the loss of any new sensations, knowing that I just gained a huge improvement in my vision without contacts or glasses. The only limitation my opthmalogist gave was that he preferred that I didn't have AN surgery for at least 4 weeks after Lasik, and to make sure that when I was in for AN that my eyes did not dry out (that meant having the MD order drops every 4 hours).
