evaluation of corneal biomechanical properties following scleral buckling using the ocular response analyzer
purpose : to evaluate corneal visco-elasticity and intraocular pressure (iop) changes measured by an ocular response analyzer (ora) after scleral buckling methods : fifty-six eyes with history of scleral buckling surgery three months ago were included in the study. corneal hysteresis (ch), corneal resistance factor (crf), corneal-compensated iop (iopcc) and goldmann-correlated iop (iopg) were m...
متن کاملEvaluation of Corneal Biomechanical Properties Following Penetrating Keratoplasty Using the Ocular Response Analyzer
PURPOSE To evaluate corneal biomechanical properties in eyes that had previously undergone penetrating keratoplasty (PK) using the ocular response analyzer (ORA). METHODS We recruited 26 patients who had received unilateral PK. Corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann-correlated intraocular pressure (IOPg), and cornea-compensated intraocular pressure (IOPcc) were mea...

متن کاملA Comparison of Corneal Biomechanical Properties of Chronic Smokers and Non-Smokers Using the Ocular Response Analyzer
Chronic smoking has negative effects on the ocular surface; chronic smokers had lower Schirmer scores in the corneas [1], a higher degree of squamous metaplasia [2,3], a higher grade of lipid layer changes in tears [3], and lower tear film break-up time compared with non-smokers [1-4]. Smoking also affects tear secretion and protein components in tears [5,6]. Furthermore, cigarette smoking may ...
متن کاملCorneal thickness- and age-related biomechanical properties of the cornea measured with the ocular response analyzer.
PURPOSE The Ocular Response Analyzer (ORA) is a new instrument that measures the corneal biomechanical response (corneal hysteresis, CH) to rapid indentation by an air jet. CH is the difference in applanation pressures (P1, P2) between the rising and falling phases of the air jet. The investigation had two parts: a characterization study and a validation study. In the characterization study, th...
