The relationship between fixation stability and retinal structural parameters in children with anisometropic, strabismic and mixed amblyopia
(2023-07-06)
Article
Open AccessBackground: Amblyopia is an ocular condition leading to structural and functional changes. The relationship between these changes is complex and remains poorly understood. (2) Methods: Participants included 31 children ... -
Loss of blink regularity and its impact on ocular surface exposure
(2023-07-13)
Article
Open AccessBackground: Changes in blink parameters have been found to influence ocular surface exposure, eliciting symptoms of dry eye and ocular signs. The aim of the study was to highlight the relevance of including blink regularity ... -
Quality of life of caregivers of children with visual impairment: a qualitative approach
(Elsevier, 2023-05-16)
Article
Restricted access - publisher's policyBackground: Receiving a diagnosis of a child with untreatable visual impairment (VI) may have a negative impact on parents and caregivers, and affect their quality of life (QoL). Aims: To use a qualitative research approach ... -
Beam-shaping extended depth of focus intraocular lens: optical assessment with corneas of increasing spherical aberration
(2023-02)
Article
Restricted access - publisher's policyPURPOSE: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 ... -
Retinal vessel local tortuosity under a macula-to-optic disc central-framing change
(2023-03-01)
Article
Open AccessSome 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 ... -
Pitfalls of using NIR-based clinical instruments to test eyes implanted with diffractive intraocular lenses
(2023-04-01)
Article
Open AccessThe strong wavelength dependency of diffractive elements casts reasonable doubts on the reliability of near-infrared- (NIR)-based clinical instruments, such as aberrometers and double-pass systems, for assessing, post-surgery, ... -
Optical and clinical outcomes of an enhanced monofocal intraocular lens for high hyperopia
(2022-09)
Article
Open AccessPurpose: To evaluate the optical and clinical performance of an enhanced monofocal intraocular lens (IOL) (TECNIS Eyhance ICB00; Johnson & Johnson Vision) in patients with high hyperopia and a short axial length. Methods: ... -
Nonlinear encryption for multiple images based on a joint transform correlator and the Gyrator transform
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-02-01)
Article
Open AccessA novel nonlinear encryption–decryption system based on a joint transform correlator (JTC) and the Gyrator transform (GT) for the simultaneous encryption and decryption of multiple images in grayscale is proposed. This ... -
Double image encryption system using a nonlinear joint transform correlator in the Fourier domain
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-02-02)
Article
Open AccessIn this work, we present a new nonlinear joint transform correlator (JTC) architecture in the Fourier domain (FD) for the encryption and decryption of two simultaneous images. The main features of the proposed system are ... -
Halo in extended depth of focus and bifocal intraocular lenses
(2022-07)
Article
Restricted access - publisher's policyPurpose: To evaluate the size and intensity of the halos generated in distance vision by bifocal and extended depth of focus (EDOF) intraocular lenses (IOLs) as a function of pupil size, lens base power and lens addition. ...
