Effects of Hydrogel Contact Lens on Corneal Biomechanics and Intraocular Pressure

INTRODUCTION:To compare the corneal biomechanical parameters and intraocular pressure (IOP) measurements with Ocular Response Analyzer (ORA) and non-contact tonometry (NCT) before and after contact lens (CL) application. 2METHODS: Fifty-eight healthy individuals were included in this prospective study.Only one eye of each individual was chosen randomly in.Corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann-correlated IOP (IOPg), corneal-compensated IOP (IOPcc) measured by ORA, and IOP measured by NCT were compared before and an hour after the hydrogel CL (with back vertex power of -3.00 Diopter) (1-Day Acuvue Moist-Etafilcon A, Johnson&Johnson) application.The data were analysed using a paired sample t-test.RESULTS: Fifty-eight eyes of 58 participants were included in the study.19 participants were female and 39 were male.The mean age of the participants was 26.53 ± 5.09.There was no statistically significant difference between the measurements of two different devices (measurements without and with CL p = 0.230 and p =
