Abstract

Prior studies have demonstrated conflicting results regarding the relationship between corneal biomechanical properties and refractive error. Thus, the purpose of this study was to compare the corneal biomechanical parameters of myopes and emmetropes.Ninety-four subjects with varying degrees of myopia (aged 29 to 74?years, spherical equivalent [SE] -0.5 to -17.5 D) and 25 emmetropes (aged 19 to 75?years, SE: -0.5 to +0.5 D) presenting at the Queen Mary Hospital, Hong Kong were recruited sequentially for this prospective study. All patients were phakic with no history of coexisting ocular disease. The corneal biomechanical parameters of the right eye of each subject were analysed using the Corvis ST non-contact tonometer. Intraocular pressure (IOP) was measured using both the Corvis ST and the Topcon Non-Contact Tonometer CT-80. Refractive error was measured by non-cycloplegic subjective and objective refractometry.High myopes (SE greater than -6.00 D) demonstrated greater mean outward applanation velocities (p?
