Summary

Small incision lenticule extraction (SMILE) procedure is a well-known procedure for the correction of myopia. The purpose of this research study is to compare the two SMILE procedures with different laser platforms (VISUMAX 500 and VISUMAX 800) used for the correction of short-sightedness. The VISUMAX 800 and VISUMAX 500 perform the same procedure, but the VISUMAX 800 is a newer platform. This study is being done to see if the newer VISUMAX 800 provides the same or better results than the VISUMAX 500.
