WebPurpose: To create a correction formula to determine the real intraocular pressure (IOP) after LASIK considering the altered corneal thickness, corneal curvature, and corneal stability. Methods: This prospective clinical trial comprised 101 eyes of 59 patients (34 women and 25 men) that underwent LASIK with a mean preoperative spherical … 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.
