purpose : to compare intraocular pressure (iop) readings measured by the ocular response analyzer (ora) with those measured by the goldmann applanation tonometer (gat) in keratoconic eyes following penetrating keratoplasty (pkp) and evaluate the influence of anatomical and biomechanical properties of the grafts on the iop measurements methods : in this cross-sectional study conducted on 45 kera...

PURPOSE To examine the interrelationships among the Ocular Response Analyzer (ORA; Reichert Ophthalmic Instruments, Buffalo, NY), Goldmann applanation tonometer (GAT), and corneal geometry measurements in a young, healthy sample. METHODS Central corneal radius, ORA, GAT, and central corneal thickness (CCT) measurements were taken in 99 subjects (age, 21 ± 2 years) who were free of ocular and ...
