Changes of corneal biomechanics in children using orthokeratology and their roles in predicting axial length progression—A prospective 2‐year study

Acta Ophthalmologica, Volume 101, Issue 7, Page 755-765, November 2023., 2023
Abstract Purpose To determine how orthokeratology (ortho‐k) affects corneal biomechanical properties in myopia control and whether corneal biomechanical parameters can predict clinical efficacy of ortho‐k. Methods A total of 125 children 7–15 years of age using ortho‐k lenses were followed in this clinical practice and data of their right eyes were ...

Intereye Differences in the Clinical Assessment of Intraocular Pressure and Ocular Biomechanics

Optometry and Vision Science, Volume 100, Issue 10, Page 688-696, October 2023., 2023
SIGNIFICANCE Clinicians and researchers will have evidence whether intereye differences confound clinical measurements of intraocular pressure or of ocular biomechanical parameters. PURPOSE The purpose of this study was to determine whether intraocular pressure and biomechanical parameters, as measured by the Ocular Response Analyzer (ORA) and by ...

Study of Corneal Biomechanics Using Corneal Visualization by Scheimpflug Technology in Corneas with Tomographic Ectasia Susceptibility [PDF]

Al-Azhar International Medical Journal, 2000
Background and Purpose: Many people seek LVC surgeries, with some complications that may develop after an intervention such as post-LASIK ectasia, studying corneal biomechanics before LVC surgeries would decrease similar complications and increase LVC ...

Repeatability and comparison of new Corvis ST parameters in normal and keratoconus eyes [PDF]

Scientific Reports, 2019
AbstractTo evaluate the repeatability of corneal biomechanical parameters in normal and keratoconus eyes, and explore factors that affects the repeatability, and further assess the diagnostic ability of new parameters. Seventy-seven keratoconus eyes of 47 patients and 77 right eyes of 77 normal subjects were recruited in current study. All participants
