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 ...
