Dual-Scheimpflug measurements of corneal power, pachymetry, ACD, and corneal aberrations for Zernike terms in the middle of the Zernike tree showed excellent repeatability.

The TSAS may be a useful, noninvasive instrument for evaluating tear stability and for classifying DTS severity.

The accuracy of IOL power calculation was comparable with AutoK, the Placido-based corneal topographer, and the combined Placido-based and dual Scheimpflug corneal topographer.
