Comparison of Myopic Small Incision Lenticule Extraction (SMILE) With VISUMAX 500 Versus VISUMAX 800 Platforms
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.
• Cycloplegic spherical equivalent of \>-1.00D
• Refractive cylinder -2.00 D or less; anisometropia \<1.00D
• Best spectacle corrected visual acuity (BSCVA) of 6/12 or better in both eyes
• Spherical or cylindrical error has progressed at -0.50 D or less per year from date of baseline measurement in both eyes
• Contact lens wearers must have removed contact lenses at least 2 weeks before the baseline measurement
• No evidence of irregular astigmatism on corneal topography in both eyes
