Aberrations under different correction methods. RMS: root mean square; UC: uncorrected (naked eyes); Total: total aberrations (2nd-to-7th-order aberrations, removing second-order defocus); HOA: higher-order aberrations (including 3rd-to-7th-order aberrations); Trefoil: trefoil aberrations (including C (3, − 3) and C (3, 3)); Coma: coma aberrations (including C (3, − 1) and C (3, 1)); SA: spherical aberrations (C (4, 0)). “a” indicates statistical significance (p < 0.05) compared with the naked eye, and “b” indicates statistical significance (p < 0.05) compared with single vision soft contact lenses (SVSCLs)
