Abstract: The present description relates to a 2D visual code based on the superposition of pure flat waves framed in black, designed to be read at long distances, with different types of degradation (noise, blurring or movement) and in adverse lighting conditions. To this end, the information carrying elements are waves that are distributed over the whole image. The combination of waves with different directions, frequencies, amplitudes and phases permits generating a high number of configurations that may be decoded in a robust and efficient manner.

Abstract: Optoelectronic binocular instrument for the automatic correction of presbyopia and method for the binocular correction of the presbyopia. The instrument has two optoelectronic lenses (103, 110; 203, 204) and a capturing subsystem for taking images of the eye. By means of the pupil tracking, which performs the processing of the eye's images, the system determines the distance where the subject is looking at. The pupil tracking works at a very high speed, using a high-performance graphic processor and a highly parallelized algorithm for pupil tracking. The method consists of two phases. In the first one a calibration is accomplished, the subject is asked to look at targets at different distances and the size and position of the pupil is measured. In the second phase the correction is performed by the instrument, the system continuously captures and processes images to calculate the correction to apply and, finally, corrects the presbyopia by applying said correction.

Abstract: The new variable power accommodative intraocular lens is comprised by a central body or optical zone that has at least four refracting interfaces that separate different materials. These are connected by means of a substrate that holds them in an equatorial manner, and which includes the bases of the fasteners of the lens embedded in its core. The lens changes its power in response to variations in the equatorial diameter of the materials that comprise the optical zone. Thanks to its design, the lens can achieve variations in the optical powers greater than one diopter per micrometer of equatorial compression. This is achieved through the real change of the curvature radii of the refracting interfaces that comprise the optical zone, as well as the central thicknesses along the length of the optical axis of the different materials that limit said refracting interfaces.

Abstract: The intraocular aberration correction lens is shaped by an optical area that has a gradient in the chromatic dispersion value of the material or materials that shape it, in such way that said gradient is parallel to the optical axis. The net value of the chromatic dispersion in the anterior area of the lens is different from the value in its posterior area. For this, the use of a single material or various is possible. The anterior and posterior surfaces of the lens, as well as the separation between adjacent materials, if applicable, have a geometric shape so that the group comprising the intraocular lens and the eye that contains it display a correction, or significant reduction, of the optical aberrations, both the chromatic ones and the monochromatic ones on and outside the optical axis. The lens can be given areas with different optical powers in a way that enables clear and simultaneous vision at different distances.

Abstract: The present invention relates to a method for measuring ocular scattering, comprising the steps of: sequentially projecting images from an extensive light source, corresponding to different visual angles, onto the retina; recording the output light in a camera or detector once it has passed through the eye twice; calculating the intensity at the center of each recorded image; calculating the PSF for each angle from the previous intensities; and calculating the average of the value of the PSF between the angles. The invention also relates to a system for carrying out said method. The invention can be used to measure the intensity of the scattered light in an objective manner.

This body is, in turn, covered by a sterile sleeve (2) that enables it to be used in different animals. A flexible duct (3) runs coaxially and its distal end connects with a bevelled needle (4) that permits insertion in the oviduct (12) at an angle of 45°. The proximal end of the flexible tube connects with a device (6) that includes a sheath (7) closed at the other end by a piston (8) that slides along the inside of the sheath and that enables the precision insertion of low-volume liquids.

This is achieved through the real change of the curvature radii of the refracting interfaces that comprise the optical zone, as well as the central thicknesses along the length of the optical axis of the different materials that limit said refracting interfaces.

Abstract: An ophthalmic instrument for measurement of ocular refraction and visual simulation and a method of measurement obtaining the ocular refraction in a binocular manner, which incorporates a digitally controlled phase modulator for generating best ophthalmic correction in each subject. The instrument enables measuring refraction, not only associated with blurring and astigmatism, but also optical aberration of any order. The phoropter can simulate vision by any phase profile, including those of a diffractive or discontinuous type. The instrument also incorporates a subsystem for presentation of stimuli that produces stereoscopic vision of the same, enabling the subject to enjoy a three dimensional perception during the process, and two output pupils. The instrument, by its electro-optical features, enables simulation of vision as it would be modified after submitting an eye to different surgical techniques, such as refractive surgery or interocular lens implantation.
