Image Formation in the Living Human Eye
Autors: Pablo Artal
Journal: The Annual Review of Vision Science
Volume: 1
Pages: 1 – 17
Year: 2015
ISBN: 978-0-8243-5101-4
ABSTRACT
The human eye is a relatively simple optical instrument that imposes the first performance limits on the visual system. This review describes the main optical properties of the eye: geometric image formation, aberrations, and intraocular scattering. The article also […]
Impact of scatter on double-pass image quality and contrast sensitivity measured with a single instrument
Autors: Juan M. Bueno, Guillermo Pérez, Antonio Benito and Pablo Artal
Journal: BioMedical Optics Express
Volume: 6, No. 12
Pages: 4841- 4849
Year: 2015
ISBN: 2156-7085
ABSTRACT
We compared objective Double-Pass (DP) image quality data with subjective visual parameters measured within the same modified instrument for different amounts of scatter. The original DP imaging channel of a clinical instrument was maintained intact and two […]
Effect of the equivalent refractive index on intraocular lens power prediction with ray tracing after myopic laser in situ keratomileusis

Journal:Journal of Cataract & Refractive Surgery
Volume: 41 (5)
Pages: 1030 – 1037
Year: 2015
ISBN: 0886-3350
ABSTRACT
PURPOSE:
To determine the impact of the equivalent refractive index (ERI) on intraocular lens (IOL) power prediction for eyes with previous myopic laser in situ keratomileusis […]

Pages: 2125–2135
Year: 2015
ISBN: 0886-3350
PURPOSE: To assess the feasibility of a new injectable telescopic intraocular lens (IOL).
SETTING: London Eye Hospital, London, United Kingdom.
DESIGN: Prospective interventional pilot study.
METHOD: Eyes with bilateral, intermediate, or advanced dry age-related macular degeneration (AMD); preoperative decimal […]
Spatial properties of fundus reflectance and red–green relative spectral sensitivity
Autors: Dimitrios Christaras, Harilaos Ginis, Pablo Artal
Journal: Journal of the Optical Society of America A
Volume: 32 (9)
Pages: 1723-1728
Year: 2015
ISBN: 1084-7529
Abstract
We investigated the spatial characteristics of the diffuse light in the eye at two different wavelengths and the extent to which this may affect red–green relative spectral sensitivity. The fundus reflectance of six subjects was […]
Second-harmonic generation microscopy of photocurable polymer intrastromal implants in ex-vivo corneas
Autors: Juan M. Bueno, Raquel Palacios, Alexandros Pennos, and Pablo Artal
Journal: Biomedical Optics Express
Volume: 6 (6)
Pages: 2211-2219
Year: 2015
ISBN: 2156-7085
Abstract:
A custom adaptive-optics (AO) multiphoton microscope was used to visualize the corneal stroma after the insertion of a photocurable polymer material. A lamellar pocket was created and a certain amount of polymer in liquid form was injected. This turned into […]
An aspheric intraocular telescope for age-related macular degeneration patients
Autors: Juan Tabernero, Muhammad A Qureshi, Scott J Robbie, and Pablo Artal
Journal: BioMedical Optics Express
Volume: 6 (3)
Pages: 1010-1020
Year: 2015
ISBN: 2156-7085
Abstract:
We have designed an intraocular telescope for the posterior chamber of the human eye of patients with age related macular degeneration. The basic design is composed of two decentered high optical power lenses ( + 66D and −66D) […]
Location of Achromatizing Pupil Position and First Purkinje Reflection in a Normal Population
Autors: Silvestre Manzanera, Pedro M. Prieto, Antonio Benito, Juan Tabernero, and Pablo Artal
Journal: IOVS
Volume: 56 (2)
Pages: 962-966
Year: 2015
ISBN: 0146-0404
PURPOSE. Quality of vision in patients who have undergone corneal refractive surgery depends
upon the optimal centration of the procedures used. The center of the pupil is used as a
reference point in some corneal ablation procedures. The […]
Dynamics of the near response under natural viewing conditions with an open-view sensor
Autors: Emmanuel Chirre, Pedro Prieto, and Pablo Artal
Journal: Biomedical Optics Express
Volume: Vol. 6, Issue 10
Pages: 4200-4211
Year: 2015
ISBN: 2156-7085
ABSTRACT:
We have studied the temporal dynamics of the near response (accommodation, convergence and pupil constriction) in healthy subjects when accommodation was performed under natural binocular and monocular viewing conditions. A binocular open-view multi-sensor based on an invisible […]

Year: 2015
ISBN: 1081-597X
Abstract
PURPOSE: To evaluate the safety and efficacy of the iolAMD technology (London Eye Hospital Pharma, London, UK), which includes two injectable, hydrophobic acrylic intraocular lenses (IOLs) in a pilot study of patients diagnosed as having cataract […]
