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. Web15 feb. 2024 · IOP correction factors are based on structurally normal corneas with no pathology. Thicker edematous cornea will result in artefactually lower GAT readings owing to reduced rigidity.
