Influence of overnight orthokeratology lens fitting decentration on corneal topography reshaping
Background This retrospective study was designed to investigate the sole influence of orthokeratology (OK) lens fitting decentration on the Zernike coefficients of the reshaped anterior corneal surface. Methods This study comprised a review of 106 right eyes and measurements of corneal topography both before OK and at 1-month follow-up visit. A routine was designed to calculate local corneal ...
متن کاملInfluence of Overnight Orthokeratology on Corneal Surface Shape and Optical Quality
Purpose To investigate the changes of corneal surface shape and optical quality during orthokeratology. Methods 49 eyes of 26 patients (10.63 ± 2.02 years old) who underwent overnight orthokeratology for myopia were prospectively examined. The corneal surface shape parameters, including surface regularity index (SRI) and surface asymmetry index (SAI), were attained with an OPD-III SCAN. The h...
متن کاملInfluence of overnight orthokeratology on axial elongation in childhood myopia.
PURPOSE This prospective study was conducted to assess the influence of overnight orthokeratology (OK) on axial elongation in children, with those wearing spectacles as controls. METHODS One hundred five subjects (210 eyes) were enrolled in the study. The OK group comprised 45 patients (90 eyes, age 12.1 ± 2.5 years, mean ± SD; OK group) who matched the inclusion criteria for OK. The control ...
متن کاملPseudomonas aeruginosa corneal ulcer related to overnight orthokeratology.
BACKGROUND Overnight orthokeratology was thought to be a safe and non-invasive alternative for low-grade myopia and astigmatism correction. We assessed histories, clinical courses, and visual outcomes of the patients with pseudomonal keratitis related to overnight orthokeratology. METHODS The records of six patients with pseudomonal keratitis related to overnight orthokeratology were reviewed...
متن کاملPredictive role of corneal Q-value differences between nasal–temporal and superior–inferior quadrants in orthokeratology lens decentration
BACKGROUND To investigate the association between pretreatment corneal parameters and orthokeratology lens decentration. METHODS This retrospective study included a total of 108 eyes in 60 myopia patients, who were divided into a lens-decentration and a control group. Various pretreatment corneal parameters were analyzed by receiver operating characteristic curves (ROC curves), including corn...
