Web20 aug. 2024 · The IOP NCT was measured using a noncontact IOP tonometer (Cannon Inc; Topcon, Tokyo, Japan). The bIOP was measured using Corvis ST. Joda et al. [ 18] used numerical analysis and validation against clinical data to develop a method to obtain the biomechanically corrected intraocular pressure (bIOP) measurements. WebIn normal young subjects, IOP NCT usually overestimates IOP GAT by 1–2 mmHg ( 21 – 23 ). Compared with that in our study, the mean difference between IOP NCT and IOP GAT in the present study was greater, which might be related to the different measuring principles and corneal biomechanics in high myopia populations.
