Trends in refractive surgery in the United States.

To determine the latest trends in refractive surgery in the United States, a survey dealing with volumes, types, preferences, and use of emerging technology was sent to 5000 U.S. members of the American Society of Cataract and Refractive Surgery. Refractive surgery techniques and the use of lasers, microkeratomes, pupillometry instruments, postoperative medications, wavefront analyzers, and topographers were examined.
