Corneal changes and wavefront analysis after orthokeratology fitting test.
PURPOSE To evaluate corneal changes and ocular aberrations during an orthokeratology test. DESIGN A prospective, nonrandomized cohort study. METHODS Fourteen myopic patients (26 eyes) underwent an orthokeratology fitting test with the BE contact lens (Ultravision Pty, Ltd, Brisbane, Australia). Best spectacle-corrected visual acuity (BSCVA), uncorrected (Ultravision Pty, Ltd, Brisbane, Aust...
متن کاملCorneal response to short-term orthokeratology lens wear.
PURPOSE This study investigated short-term corneal changes induced by reverse-geometry lenses worn for orthokeratology. METHODS Nine young adult subjects wore reverse-geometry rigid gas-permeable lenses (BE; UltraVision Contact Lenses, Brisbane, Australia) in one eye only for 10, 30, and 60 min in the open eye and 8 h in the closed eye. The fellow eye acted as a non-lens-wearing control. Corn...
متن کاملThe relationship between corneal biomechanics and anterior segment parameters in the early stage of orthokeratology
To investigate the relationship between corneal biomechanics and anterior segment parameters in the early stage of overnight orthokeratology.Twenty-three eyes from 23 subjects were involved in the study. Corneal biomechanics, including corneal hysteresis (CH) and corneal resistance factor (CRF), and parameters of the anterior segment, including corneal curvature, central corneal thickness (CCT)...
متن کاملCorneal thickness changes in hyperopic orthokeratology measured by optical pachometry.
PURPOSE To investigate the time course of corneal thickness changes in overnight hyperopic orthokeratology (OK) lens wear for a 4-day lens-wearing period. METHODS Fourteen subjects (age range, 20-37 years) were fitted with hyperopic OK lenses in one eye only. The fellow eye acted as a non-lens wearing control. Lenses were worn overnight only for 4 nights, and changes from baseline in subjecti...
متن کاملcorneal thickness changes after soft contact lens removal
purpose: to evaluate corneal thickness changes after soft contact lens (scl) removal in lasik candidates. methods: fifty lasik candidates (100 eyes) with history of daily wear scl for at least 6 months were enrolled in this descriptive study. central corneal thickness was measured by ultrasonic pachymetry immediately after lens removal and then repeated daily at the same time, until the thickne...
