Binocular open-view system to perform estimations of aberrations and scattering in the human eye
(2015-11-10)
Article
Open AccessWe present a system that integrates a double-pass (DP) instrument and a Hartmann-Shack (HS) wavefront sensor to provide information not only on aberrations, but also on scattering occurring in the human eye. A binocular ... -
Clinical evaluation of an automated subjective refraction method implemented in a computer-controlled motorized phoropter
(Elsevier, 2018-10-01)
Article
Open AccessPurpose To investigate a new algorithm to perform an automated non-cycloplegic refraction in adults. Methods Fifty healthy subjects were measured twice (test–retest) with the new automated subjective refraction method ... -

Effect of apparent depth cues on accommodation in a Badal optometer
(2017-11-01)
Article
Open AccessBackground: The aim was to analyse the effect of peripheral depth cues on accommodation in Badal optometers. Methods: Monocular refractions at 0.17 and 5.00 D of accommodative stimulus were measured with the PowerRef ... -
Effect of Experimental Conditions in the Accommodation Response in Myopia
(2017-10-19)
Article
Open AccessSIGNIFICANCE The accommodative response is more affected by the type of refractive error than the method of stimulation, field of view (FOV), or stimulus depth. PURPOSE This study aims to analyze the effect of stimulation ... -

Medida de la birrefringencia óptica en las fibras textiles. Parte 1. Demostración teórica
(2006-07)
Article
Open AccessEn este trabajo se desarrollan los aspectos teóricos de la medida de la birrefringencia en cuerpos anisotrópicos por el método de Nikitin-Berek. También se desarrolla su aplicación específica a medidas de la birrefringencia ... -
Medida de la respuesta acomodativa con un sistema de doble paso: aplicación al estudio de la acomodación en función de la edad.
(Universitat Politècnica de Catalunya, 2012-10-22)
Doctoral thesis
Open AccessAccommodation, defined as the dioptric change of the eye, enables clear vision at different distances. Its study is interesting due to different aspects: the progressive loss of amplitude of accommodation known as presbyopia, ... -
Medida del retraso acomodativo con la técnica de doble paso
(2009)
Conference report
Restricted access - publisher's policyLa acomodación se define como el cambio dióptrico en la potencia del ojo, que permite ver nítidamente a diferentes distancias. La profundidad de foco del ojo hace que se puedan ver objetos cercanos nítidamente con menor ... -

New compact open-field double-pass system with asymmetric focus
(2018-01-01)
Article
Open AccessEvery day more people are using multifocal systems to correct presbyopia, as for example contact lenses or intraocular lenses. As a consequence, the necessity to do an appropriate characterization of their optical quality ... -
Optical quality and intraocular scattering assessed with a double-pass system in eyes with contact lens induced corneal swelling
(2014-08-01)
Article
Restricted access - publisher's policyPurpose: To evaluate the impact of contact lens (CL)-induced corneal swelling on the optical quality of the eye by means of the double-pass technique.; Methods: Measurements of 6 healthy subjects were obtained in 5 visits ... -
Optics of astigmatism and retinal image quality
(INTECH, 2012-02)
Part of book or chapter of book
Open AccessIn the first part of this chapter, the optical condition of astigmatism is defined. The main causes and available classifications of ocular astigmatism are briefly described. The most relevant optical properties of image ... -

Reducing speckle in double-pass systems using focus tunable lenses
(2014)
Conference report
Restricted access - publisher's policySpeckle arises in double-pass systems when coherent light is reflected by the retina. Since it degrades the images that are used to characterize the eye, there is special attention in reducing speckle when working with ...
