    PURPOSE:To assess the optical quality and halo formation of a beam-shaping extended depth-of-focus (EDOF) intraocular lens (IOL) (AcrySof IQ Vivity; Alcon Laboratories, Inc) with corneas of long-range spherical aberration ...

  • System for objective assessment of the accommodation response during subjective refraction 

    García Guerra, Carlos Enrique; Martínez Roda, Juan Antonio; Ondategui Parra, Juan Carlos; Turull Mallofré, Aina; Aldaba Arévalo, Mikel; Vilaseca Ricart, Meritxell (Association for Research in Vision and Ophthalmology (ARVO), 2023-05)
    Article
    Open Access
    Purpose: 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 ...

  • Feasibility of measuring fusional vergence amplitudes objectively

    Two tests to measure fusional vergence amplitudes objectively were developed and validated against the two conventional clinical tests. Forty-nine adults participated in the study. Participants’ negative (BI, base in) and ...

  • A Preliminary study of deep learning sensor fusion for pedestrian detection 

    Chávez Plascencia, Alfredo; García Gómez, Pablo; Bernal Pérez, Eduard; Mas Giménez, Gerard de; Casas Pla, Josep Ramon; Royo Royo, Santiago (Multidisciplinary Digital Publishing Institute (MDPI), 2023-04)
    Article
    Open Access
    Most pedestrian detection methods focus on bounding boxes based on fusing RGB with lidar. These methods do not relate to how the human eye perceives objects in the real world. Furthermore, lidar and vision can have difficulty ...

  • Retinal vessel local tortuosity under a macula-to-optic disc central-framing change 

    Ramírez Cano, Natalia; Rallo Capdevila, Miguel; Millán Garcia-Varela, M. Sagrario (2023-03-01)
    Article
    Open Access
    Some ocular and cardiovascular diseases can be detected through the increased tortuosity of retinal blood vessels. Objective tortuosity measures can be obtained from digital image analysis of a retinography. This study ...

  • Membrane protein detection and morphological analysis of red blood cells in hereditary spherocytosis by confocal laser scanning microscopy 

    Rey Barroso, Laura; Roldán Molina, Mónica; Burgos Fernández, Francisco Javier; Isola, Ignacio Mario; Ruiz Llobet, Anna; Gassiot Riu, Susanna; Sarrate Garcia, Edurne; Vilaseca Ricart, Meritxell (2023-04)
    Article
    Open Access
    In hereditary spherocytosis (HS), genetic mutations in the cell membrane and cytoskeleton proteins cause structural defects in red blood cells (RBCs). As a result, cells are rigid and misshapen, usually with a characteristic ...
