Notes: *IOLMaster 700 – Argos. Note that P-values for keratometry are based on GEE models with covariates of AL and ACD. P-values for postoperative month 1 refraction are based on GEE models with covariates of lens choice, baseline delta K, AL, and ACD.

Abbreviations: D, diopters; SD, standard deviation; SE, spherical equivalent.
