摘要： 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.

摘要： 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.

摘要： 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.
