Assessment of corneal biomechanics, tonometry and pachymetry with the Corvis ST in myopia [PDF]

Scientific Reports, 2021
AbstractTo evaluate the repeatability of Corvis ST corneal biomechanical, tonometry and pachymetry measurements, and agreement of pachymetry measures with the Pentacam HR and RTVue OCT. Three consecutive measurements of the right eye of 238 myopic subjects were acquired with the Corvis ST, Pentacam HR, and RTVue OCT.
