Peripheral refraction and higher-order aberrations with cycloplegia and fogging lenses using the BHVI-EyeMapper
PURPOSE To determine if a fogging lens ameliorates accommodative effects driven by the closed-view design of the BHVI-EyeMapper (EM) instrument. We compared cycloplegic refraction and higher-order aberration measurements of the EM with those obtained with a fogging lens. METHODS Twenty-six, young, participants (15F, 25±5 years, range: 18-35 years, SE: +0.25 D and -3.50 D) with good ocular hea...
متن کاملThe BHVI-EyeMapper: Peripheral Refraction and Aberration Profiles
PURPOSE The aim of this article was to present the optical design of a new instrument (BHVI-EyeMapper, EM), which is dedicated to rapid peripheral wavefront measurements across the visual field for distance and near, and to compare the peripheral refraction and higher-order aberration profiles obtained in myopic eyes with and without accommodation. METHODS Central and peripheral refractive er...
متن کاملInfluence of fogging lenses and cycloplegia on open-field automatic refraction.
PURPOSE To compare refractive values measured with and without cycloplegia, or with fogging lenses, using an open-field auto-refractor. METHODS One hundred and forty-two young adults were enrolled from a university population; 96 were female (67.6%) and 46 were male (32.4%), the age range was 18-26 years (mean 22.3 +/- 3.7 years). The refraction measurement was obtained for the right eye of e...
متن کاملChanges in Peripheral Refraction, Higher-Order Aberrations, and Accommodative Lag With a Radial Refractive Gradient Contact Lens in Young Myopes.
PURPOSE To evaluate changes in the peripheral refraction (PR), visual quality, and accommodative lag with a novel soft radial refractive gradient (SRRG) experimental contact lens that produces peripheral myopic defocus. METHODS 59 myopic right eyes were fitted with the lens. The PR was measured up to 30° in the nasal and temporal horizontal visual fields and compared with values obtained with...
متن کامل[Relationship between high-order aberrations and age and between high-order aberrations and refraction errors].
PURPOSE To evaluate the relationship between high-order aberrations and refractive errors, and between high-order aberrations and age. METHODS An analytic retrospective study of patients that underwent aberrometry examination was conducted. All subjects examined with LadarWave aberrometer at the Hospital de Olhos do Paraná from April 2004 to April 2005 were included in this study. The major i...
