[Thésaurus Mesh]Réfraction oculaireMots-clés : Comparaison clinique technologie de réfraction haute résolution Résumé : SIGNIFICANCE: Recently, novel refraction technology allows subjective refractions to be performed with a higher-resolution. Itis unclear, however,if these benefits are noticed and appreciated by the patient during the examination and after dispensing. PURPOSE: This study investigated benefits and drawbacks of high-resolution refraction technology over standard, specifically in terms of the refraction, glasses prescription, and participant's perceptions of the technology. METHODS: Sixty progressive-addition-lens wearers (aged 35 to 70 years) and 60 single-vision wearers (18 years or older) were randomized to a high-resolution refraction (Vision-R 800; Essilor Instruments, Dallas, TX; essilorinstrumentsusa.com) and standard refraction in a 2-week crossover dispensing design. Refractive results were converted to M, J0, and J45 and analyzed using multivariate t tests. Bayesian estimation was used to analyze differences between refraction type and age group for subjective outcomes. RESULTS: Differences in refractive error between the two refractions were small, and none differed statistically (P > .05) or clinically (e.g., Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus HELB]:Optique:aberromètreRésumé : SIGNIFICANCE: Measurement of ocular aberrations is a critical component of many optical corrections. PURPOSE: This study examines the accuracy and repeatability of a newly available high-resolution pyramidal wavefront sensor–based aberrometer (Osiris by Costruzione Strumenti Oftalmici, Firenze, Italy). METHODS: An engineered model eye and a dilated presbyopic eye were used to assess accuracy and repeatability of aberration measurements after systematic introduction of lower- and higher-order aberrations with calibrated trial lenses (sphere +10.00 to −10.00 D, and astigmatic −4.00 and −2.00 D with axis 180, 90, and 45°) and phase plates (−0.57 to 0.60 μm of Seidel spherical aberration defined over a 6-mm pupil diameter). Osiris aberration measurements were compared with those acquired on a previously calibrated COAS-HD aberrometer for foveal and peripheral optics both with and without multizone dual-focus contact lenses. The impact of simulated axial and lateral misalignment was evaluated. RESULTS: Root-mean-square errors for paraxial sphere (corneal plane), cylinder, and axis were, respectively, 0.07, 0.11 D, and 1.8° for the engineered model and 0.15, 0.26 D, and 2.7° for the presbyopic eye. Repeatability estimates (i.e., standard deviation of 10 repeat measures) for the model and presbyopic eyes were 0.026 and 0.039 D for spherical error. Root-mean-square errors of 0.01 and 0.02 μm, respectively, were observed for primary spherical aberration and horizontal coma (model eye). Foveal and peripheral measures of higher- and lower-order aberrations measured with the Osiris closely matched parallel data collected with the COAS-HD aberrometer both with and without dual-focus zonal bifocal contact lenses. Operator errors of focus and alignment introduced changes of 0.018 and 0.02 D/mm in sphere estimates. CONCLUSIONS: The newly available clinical pyramidal aberrometer provided accurate and repeatable measures of lower- and higher-order aberrations, even in the challenging but clinically important cases of peripheral retina and multifocal optics.
