Pachymetry and iop adjustment
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. Broadly, a decrease in IOP is found post-surgery, with LASIK reducing IOP to a greater extent than PRK, and myopic WebSince OHTS, doctors are advised to measure corneal thickness along with IOP. But the existing nomograms that adjust for corneal thickness are considered unsatisfactory. Hence the search for a device that measures pressure independent of corneal variables. ... In the meantime, Dr. Stamper recommends that physicians perform pachymetry on every ...
