WebIn fact, an adjustment based on CCT might lead you to “correct” the pressure downward, when the true IOP is actually greater than the measured pressure, such as with Fuchs' corneal dystrophy. One 580-µm cornea may be altering the IOP reading very differently than another, depending on the biomechanical properties of the individual corneas.

WebIOP based on CCT alone.12 The refractive surgery procedure affects the entire biomechanics of the cornea and, as such, the IOP found post-surgery is as a result of a change in corneal curvature, CCT and elasticity.
