In a multicenter database, modern formulas outperformed Haigis-L and Shammas-PL, while versions using posterior corneal curvature were more accurate than corresponding no-PCC methods.
In a retrospective series of 158 eyes, retreatment improved vision and refraction, but LASIK, PRK and ICL groups differed greatly in size and were selected by clinical indication.
In a multicenter retrospective cohort of 919 patients, SMILE was associated with less residual myopia and greater refractive stability, but procedure selection was not randomized.
In an early nonrandomized series, ray-tracing LASIK more often achieved 20/20 and left less cylinder than SMILE Pro, but the comparison reflects one surgeon's initial experience.
A network meta-analysis of 50 studies and 5,141 eyes compared aberrations after laser procedures and phakic ICL implantation. ICL ranked best, but optical metrics are not equivalent to overall clinical effectiveness.
A retrospective comparison of 598 eyes found high refractive accuracy after FS-LASIK, SMILE and phakic ICL implantation, but different central and peripheral aberration profiles at six months.
