Canvis relatius en la refracció perifèrica en escolars.
(Universitat Politècnica de Catalunya, 2015-06-29)
Bachelor thesis
Open AccessDiversos estudis han demostrat que la retina perifèrica juga un paper important en la determinació del creixement de l’ull, que té un efecte sobre el creixement de la longitud axial, i pot participar en el procés ... -
Canvis relatius en la refracció perifèrica en infants preescolars.
(Universitat Politècnica de Catalunya, 2015-06-29)
Bachelor thesis
Open AccessNombrosos estudis han demostrat que el desenvolupament de l’error refractiu és un procés manipulable, fins i tot un cop finalitzat el procés d’emmetropització. S’ha suggerit que quan es fa coincidir una imatge enfocada ... -
Cascaded Conical Refraction
(Universitat Politècnica de Catalunya / Universitat Autònoma de Barcelona, 2011-07-19)
Master thesis
Open AccessEnglish: After a brief introduction to the conical refraction phenomenon, the formation of transverse intensity patterns by a cascade of biaxial crystals with alignedoptic axes is studied in detail. Up to 2^(N-1) concentric ... -
Correlación y concordancia entre la técnica de retinoscopia de Mohindra y la retinoscopia con ciclopléjico en la infancia
(2022-01)
Article
Open AccessAntecedentes y objetivo: La retinoscopía, como técnica objetiva de evaluación del estado refractivo, es especialmente útil en la edad infantil. La técnica de Mohindra (RM) es una alternativa para aquellos pacientes en los ... -

Generalized ray tracing method for the calculation of the peripheral refraction induced by an ophthalmic lens
(2015-02-01)
Article
Restricted access - publisher's policyPeripheral refraction, the refractive error present outside the main direction of gaze, has lately attracted interest due to its alleged relationship with the progression of myopia. The ray tracing procedures involved in ... -
Impact of lens material on objective refraction in eyes with trifocal diffractive intraocular lenses
(2021-01-01)
Article
Open AccessPurpose: Compare subjective (Rx) and objective (ObjRx) refractions outcomes with two autorefractors models and an aberrometer in eyes implanted with a hydrophobic trifocal IOL (FineVision POD F GF, Physiol, Liége, Belgium) ... -
Ionospheric signal propagation simulator for earth observation missions
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Open AccessFollowing the discovery of the ionosphere by Marconi in 1901, different disciplines have been influenced from the ionospheric effects on radio-waves, such as communications or Earth Observation missions. The ionosphere ... -
Macular changes in children with refractive amblyopia
(Universitat Politècnica de Catalunya, 2018-02-01)
Master thesis
Open AccessPURPOSE: To determinewhether amblyopia is associated with changes in retinal thickness.METHODS: Study design was observational, combining retrospective and prospective elements. Twenty-nine subjects aged between 4 and 12 ... -

System for objective assessment of the accommodation response during subjective refraction
(Association for Research in Vision and Ophthalmology (ARVO), 2023-05)
Article
Open AccessPurpose: To evaluate a system based on a Hartmann–Shack wavefront sensor attached to a phoropter that allows the user to obtain real-time information about the refractive state of the eye and the accommodation response ... -
Wide-angle reflection and refraction seismic profile from the outer part of the gulf of Cadiz: nearest-seis cruise.
(SARTI (Technological Development Centre of Remote Acquisition and Data processing Systems), 2010-03-10)
Article
Open AccessWe will explain the first interpretations from a marine refraction and wide-angle reflection seismic profile acquired in the outer part of the Gulf of Cadiz in November 2008, in the framework of the Nearest-Seis cruise.
