DETERMINATION OF THE OPTIMAL POSITIONING OF OPHTHALMIC DEVICES BY THE USE OF PROCESSING TECHNIQUES AND SELF-FOCUS OF IMAGES.

摘要

Ophthalmic laser vision correction device, characterized in that it comprises a positioning system (200), which includes: an image collection system (202) that can be operated to collect a series of images of an eye, in which a relative distance between the image collection system and the eye is varied; a processing system (204) functionally coupled to the image collection system (202), in which the processing system (200) can be operated to: perform (304) a sharpness function in each of the collected images; compare (306) the results of the sharpness function; identify (308) the image associated with the highest sharpness function, optimizing the image focus within the image that has the highest sharpness function; and identify (310) the relative distance between the image collection system and the eye for the image associated with the highest sharpness function; and in which the positioning system (200) can function to match (312) a real distance between the ophthalmic device and the eye with the relative distance between the image collection system (202) and the eye for the associated image With the highest sharpness function.
