Fig. 4From: Myopic Laser-Assisted Subepithelial Keratectomy (LASEK) outcomes using three different excimer laser platforms: a retrospective observational studyAttempted versus achieved spherical equivalent refraction scatterplots at 3 months after LASEK with MMC for myopia correction in the Allegretto, Esiris and Technolas groups. The linear regression equation and coefficient of determination (r2) are displayed. LASEK = Laser-assisted subepithelial keratomileusis; MMC = Mitomycin C. a- Allegretto, b- Esiris, c-TechnolasBack to article page
