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 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...
متن کاملcontrast sensitivity and higher-order aberrations in myopes
purpose: to investigate the relationship between higher-order aberrations (hoas) and contrast sensitivity function (csf) in myopes. methods: in this cross-sectional study, hoas and csf were measured in myopic eyes over a 6-mm pupil. pupil diameter was measured in photopic condition. the correlation between hoas and csf was investigated using multivariate linear regression analysis. results: sev...
متن کاملMonocular amblyopia and higher order aberrations
This study compared the corneal and total higher order aberrations between the fellow eyes in monocular amblyopia. Nineteen amblyopic subjects (8 refractive and 11 strabismic) (mean age 30 ± 11 years) were recruited. A range of biometric and optical measurements were collected from the amblyopic and non-amblyopic eye including; axial length, corneal topography and total higher order aberrations...
