Corneal biomechanics as a function of intraocular pressure and pachymetry by Dynamic Infrared Signal and Scheimpflug Imaging Analysis in normal eyes – Accepted Manuscript

Abstract: Purpose: To evaluate corneal biomechanical deformation response using Ocular Response Analyzer (ORA) and Corvis ST data.Design: Prospective Observational case control studyMethods: 1262 eyes of 795 patients were enrolled. 3 groups were established, according to the corneal compensated intraocular pressure (IOPcc), group I (10-13mmHg), group II (14-17mmHg), and group III (18-21mmHg). Each group included 3 subgroups, based on central corneal thickness (CCT), subgroup 1 (465-510㎛), 2 (510-555㎛), and 3 (555-600㎛). In addition, similar groups of CCT were divided into subgroups of IOPcc. Corneal hysteresis (CH) and corneal resistance factor (CRF) were derived from ORA. The parameters of highest concavity with (Read more...)
