    Lentes que controlan la luz.
    (Franja visual, 2020) Bonnin Arias, Cristina Natalia; Sánchez Ramos, Celia; Rodríguez Alonso, Xabier; Gutiérrez Jorrín, Sara
    Este artículo se propone conocer la cantidad de luz para todo el espectro visible que alcanza los ojos de las personas en un día nublado y en un día soleado; en función de la posición de mirada del individuo. Se ha querido realizar un ejercicio experimental en esta primera parte, para conocer cuánta luz en fotones llega hasta los ojos de los peatones. Para ello y en todas las medidas se ha utilizado el espectrofotómetro OceanOptics USB2000+ junto con el software SpectraSuite. Este dispositivo realiza mediciones en cuantas de luz (fotones) del rango del espectro comprendido entre 200 y 1100 nm. Como receptor se empleó una fibra óptica muy sensible.

    Protección del sol en la montaña: Los ojos son más vulnerables.
    (Franja visual, 2020) Bonnin Arias, Cristina Natalia; Gutiérrez Jorrín, Sara; Rodríguez Alonso, Xabier; Domínguez Valdés, Teresa; Sánchez Ramos, Celia
    El uso de lentes para protección solar está extendido a casi todos los ámbitos de la vida diaria en exterior; sin embargo, determinadas activi dades y condiciones requieren una especial atención al seleccionar los lentes más adecuados. Éste es el caso de los deportes y actividades de montaña (senderismo, alpinismo, escalada y otros).

    Protección ocular en deportes acuáticos.
    (Franja visual, 2019) Bonnin Arias, Cristina Natalia; Sánchez Ramos, Celia; Rodríguez Alonso, Xabier; Gutiérrez Jorrín, Sara.
    Como de todos es sabido, existen dos tipos de deportes acuáticos, aquellos que se realizan fuera del agua, también llamados deportes náuticos, como el surf, la vela o el piragüismo; y los que se realizan dentro del agua, como la natación, el waterpolo o la natación en aguas abiertas, y por tanto también existen diversas opciones para la protección ocular.

    La luz solar: ¿Cómo se modifica para iniciar la visión?
    (franja visual, 2018) Bonnin Arias, Cristina Natalia; Gutiérrez Jorrín, Sara.; Rodríguez Alonso, Xabier; Sánchez Ramos, Celia
    La energía radiante es una forma de energía que puede propagarse en el vacío y está constituida por ondas electromagnéticas. El espectro electromagnético es la distribución energética del conjunto de las ondas que emite (Espectro de emisión) o absorbe (espectro de absorción) una sustancia e incluye una amplia gama de radiaciones, desde los rayos gamma y los rayos X, pasando por la radiación ultravioleta, la luz "visible" y los rayos infrarrojos, hasta las ondas de radio.

    RapiDA V1: Repeatability
    (2023) Martínez Álvarez, Belén; Toure Sarr, Mame Diatou; Sarco Silva Erika; Bonnin Arias, Cristina Natalia; Blázquez Sánchez, Vanesa; Sánchez Ramos, Celia
    Dark Adaptation (DA) refers to the slow recovery of visual sensitivity in the dark, mediated primarily by rods, after being exposed to intense or prolonged illumination. It has been shown that DA is slower in aging and in age-related eye diseases such as macular degeneration (AMD). It may be a key biomarker of retinal health. (Murray et al., 2022) Traditionally the method of measuring DA with produces a triphasic curve which can last between 30 to 40 minutes. The RapiDA device, has been designed to produce a biphasic curve: the alpha point, cone threshold (CT), tau, the cone time constant and S2 the slope of the rod-only section. These data can be collected within 10 minutes.

    Evaluation Of The Effects Of Tecnis Eyhance And Acrysof Iq Vivity Intraocular Lenses On Visual Quality Under Different Lighting Conditions.
    (2023) Baoud OuldHaddi, Inas; Dorronzoro Ramírez, Emilio; Flores Cervantes, Dayan; Blázquez Sánchez, Vanesa; Bonnin Arias, Cristina Natalia; Sánchez Ramos, Celia
    Introduction: Presbyopia correction surgeries undergo a thorough evaluation, combining objective measurements like visual acuity, contrast sensitivity, glare disability, and halometry, along with subjective assessments through satisfaction questionnaires. This comprehensive approach ensures accurate assessment of outcomes. To meet individual patient needs, various designs and types of intraocular lenses are available. Among the latest advancements are Extended Depth of Focus (EDOF) lenses, providing both distance and intermediate vision capabilities, offering improved visual functionality for presbyopia patients. Purpouse: To analyze the effect of the design of Tecnis® EyhanceTM and AcrySof® IQ VivityTM, extended range intraocular lenses on patients visual quality under photopic and mesopic lighting conditions. Setting: The study was performed at the Hospital Universitario Sanitas la Moraleja in Madrid. All surgeries were performed by the same experienced surgeon (E.D.R). The study followed the principles of the Declaration of Helsinki. CONCLUSION: The AcrySof® IQ VivityTM and Tecnis® EyhanceTM designs provide optimal AV, at distances (far and near), in both photopic and mesopic illumination conditions. The AcrySof® IQ VivityTM IOL provides better intermediate VA, in mesopic conditions, than the Tecnis® EyhanceTM IOL. However, this difference does not translate into a perceived subjective improvement in patients quality of life. The design of the AcrySof® IQ VivityTM and Tecnis® EyhanceTM extended range

    Analysis Of The Effects Of Two Extended-Depth- Of -Focus Intraocular Lenses On Visual Quality Under Different Illumination Conditions.
    (2023) Baoud Ould Haddi, Inas; Dorronzoro Ramirez, Emilio; Flores Cervantes, Dayan; Blázquez Sánchez, Vanesa; Bonnin Arias, Cristina Natalia; Sánchez Ramos, Celia
    INTRODUCTION: Currently, patients have an increased demand and high expectations for good visual quality and spectacle independence after surgery. In addition, said surgery is being performed earlier and earlier due to the visual demands that require good vision at all distances. Especially, in intermediate distances due to the appearance of new technologies and the continuous work on screens. For this reason, there is a continuous evolution of IOL designs. PURPOSE: To analyze the effect of PhysiOL ®IsoPure123™ and AcrySof ®IQ Vivity™ extended range intraocular lens design on patients visual quality under photopic and mesopic illumination conditions. Setting: The study was performed at the Hospital Universitario Sanitas la Moraleja in Madrid. All surgeries were performed by the same experienced surgeon (E.D.R). The study followed the principles of the Declaration of Helsinki. CONCLUSION: Both AcrySof ®IQ Vivity™ and PhysiOL ®IsoPure 123™ intraocular lens designs provide optimal VA for far and near distances in both photopic and mesopic illumination conditions. The AcrySof ® IQ Vivity™ IOL provides better intermediate VA under mesopic conditions than the PhysiOL ® IsoPure 123™ IOL, with this difference being clinically significant. There was no statistically significant difference between the two intraocular lenses in relation to the perception of halos.
