As soon as a flap is made essentially everyone gets dry eyes after LASIK. For that reason, we suggest that patients start on a drop called Restasis which increases your own natural tear production as soon as possible before surgery. Many patients are sensative to preservatives early after surgery and we recommend tear drops without preservatives for the first week after surgery. After the first week, most people can use tear drops with preservatives or without. The key is to use them with adequate frequency and in general, most people have better vision after surgery when they use lubrication at least every hour or two for the first several weeks.
