After propensity matching 27 eyes per group, no clinically meaningful 12-month difference in haze, vision, tomography or aberrations was detected between strategies.
In a randomized 30-patient study, ray-tracing-guided LASIK did not increase total higher-order aberrations at three months, unlike wavefront-optimized treatment.
In 146 eyes, measured corneal thinning differed from the surgical plan. The gap was associated with baseline corneal geometry and selected aberrations, but an effect on perceived visual quality was not established.
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.
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.
