WebCCT is even more unreliable as a correction factor for IOP if the cornea has been surgically modified, because both the CCT and the corneal biomechanics have likely been altered. In one study, 13 applanation tonometry produced both lower and higher IOP measurements postoperatively versus preoperatively, despite all subjects' having reduced corneal … Web3 jan. 2024 · One of the limitations of this method is that it is strongly affected by the central corneal thickness (CCT) so that increasing the CCT leads to an overestimation of IOP [4, 5]. To reduce the effect of CCT on IOP measurement, a parameter called IOP corneal-compensated (IOPcc) was introduced by the ocular response analyzer (ORA).
