Optoelectronic binocular instrument for the automatic correction of presbyopia and method for the binocular correction of the presbyopia. The instrument has two optoelectronic lenses () 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.

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. Preferably the intraocular lens works in combination with a capsular ring, to which the haptics are fixed and whose external diameter determines the power of the lens. The change of power mechanism in the lens initiates with the contraction of the ciliary muscle of the patient in response to the accommodative force.

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.

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.
