Patent number: 10022048Abstract: Method, system and computer program for measuring light diffusion in the eyeball or in the ocular region. The method comprises: projecting a punctiform light beam onto the retina; correcting low-order ocular aberrations of the eye; capturing and recording an image of the retinal plane formed after reflection of the punctiform light beam on the retina and a double passage through the ocular media of the eye; and at the same time as capturing the image of the retinal plane, performing a high- and low-order ocular aberration measurement in the plane of the pupil and performing a light diffusion measurement, combining ocular aberration measurement information with information on the image of the retinal plane. The system and the computer program are adapted for implementing the method.Type: GrantFiled: July 29, 2015Date of Patent: July 17, 2018Assignee: UNIVERSITAT POLITECNICA DE CATALUNYAInventors: Jaume Pujol Ramo, Montserrat Arjona Carbonell, Carlos Enrique Garcia Guerra, Mikel Aldaba Arévalo, Meritxell Vilaseca Ricart, Fernando Díaz Doutón

Patent number: 9750406Abstract: The invention relates to a method for the detection of visual function losses. The method comprises analysing the optical quality of a patient's eye based on one or more retinal images thereof or based on information relating to retinal images corresponding to an eye having an anterior segment and intraocular means that are healthy. The method comprises: detecting a visual function loss of the visual system of functional or pathological etiology, based on the result of the aforementioned analysis; and determining if this loss is due to a reduced and/or limited neural response, which induces alterations in the innervation of the intrinsic ocular muscles of the eye.Type: GrantFiled: May 3, 2013Date of Patent: September 5, 2017Assignee: UNIVERSITAT POLITECNICA DE CATALUNYAInventors: Jaume Pujol Ramo, Juan Carlos Ondategui Parra, Maritxell Vilaseca Ricart, Montserrat Arjona Carbonell, Rosa Borrás Garcia

Patent number: 8764191Abstract: It is applied to bifocal, multifocal or progressive intraocular lenses or contact lenses, multifocal corneal ablation or other multifocal configurations, comprising means for projecting the image of a point light source on the retina of a patient and an assembly for directly recording the light reflected in said retina after the double passage of the light through the ocular means, integrating a first focus corrector device inserted in the path of the light beam guided towards the retina and a second focus correction device inserted in the light beam reflected from the retina, to be guided towards the mentioned recording means, each of said focus correction devices having independent control means for controlling the operation thereof.Type: GrantFiled: May 3, 2011Date of Patent: July 1, 2014Assignee: Universitat Polytècnica de CatalunyaInventors: Jaume Pujol Ramo, Sergio Òscar Luque, Fernando Díaz Doutón

Method and System for Simulating/Emulating Vision Via Intraocular Devices or Lenses prior to Surgery
Publication number: 20130250245Abstract: A method and system for simulating/emulating vision using intraocular devices or lenses prior to surgery, preferably using multifocal and monofocal intraocular lenses. The invention allows the patient, prior to surgery, to compare the differences in the perception of an image as seen with the intraocular lens and with normal vision, determining which type of lens the patient prefers, and in turn allows the ophthalmologist to measure which provides the better visual performance. The invention comprises a system containing the intraocular lens, called an artificial eye, a lens for transporting the image from the intraocular lens and eliminating the blur introduced by the artificial eye, and at least one telescope or optometer which transports the intermediate image from the intraocular lens onto the patient's pupil. In this manner, the patient is shown how he/she would see after surgery with each type of lens proposed by the ophthalmologist.Type: ApplicationFiled: October 14, 2011Publication date: September 26, 2013Inventors: Sergio Oscar Luque, Jaume Pujol Ramo -

Patent number: 8488851Abstract: The invention relates to a system and method for measuring light diffusion in the eyeball or eye region, by recording and processing retinal images. The inventive system includes a double-pass ophthalmoscopic system having means for correcting low-order aberrations. Said system can be used to record images of the plane of the retina on a CCD camera, the outer part of said images containing information relating to ocular scattering. The aforementioned images can be used to obtain the objective scattering index (OSI), providing the ratio between the energy on the outer part of the image and the energy in the central part, or, alternatively, the modulation transfer function (MTF) area can be used for this purpose once the low frequencies have been filtered. According to the inventive method, the low-order aberrations are corrected before a retinal image or a temporal sequence of retinal images is captured and recorded.Type: GrantFiled: May 5, 2008Date of Patent: July 16, 2013Assignee: Universitat Politecnica de CatalunyaInventors: Pablo Artal Soriano, Jaume Pujol Ramo, Sergio Oscar Luque, Antonio Benito Galindo, Guillermo Pérez Sanchez

Patent number: 8366270Abstract: The invention relates to a method and system for the objective measurement of ocular accommodation. A double-pass ophthalmoscopic system is used which incorporates a periscope allowing the patient to binocularly see real objects in an open field and images of the retinal plane to be recorded on a CCD camera. The method includes obtaining, for different values of accommodation stimulation, a set of retinal images corresponding to different focal values in the retina, obtaining the different focal positions in the retina by moving the two lenses incorporated in the ophthalmoscopic system. The image with the best optical quality is obtained for each set of images and by associating the selected image with the known value of the accommodation stimulation it is possible to objectively measure the accommodation.Type: GrantFiled: April 30, 2009Date of Patent: February 5, 2013Assignee: Universitat Politecnica de CatalunyaInventors: Jaume Pujol Ramo, Sergio Oscar Luque, Mikel Aldaba Arévalo
