I had laser surgery on 5/9/14. I had some dry eye issues before whenever I wore my contacts. I understand that is usual with contact wearing. I wore my glasses M-F for work & contacts on most weekends. My Dr. advised me everyone's are different & some become more dry than others. I also had the dissolvable tear drops put in, I was -3.50 in both eyes before surgery & could see much better the next day.
