Materials customization method by diagnosis of biofunctionality of retinal photoreceptor cells and biomedical equipment


The present invention relates to a new biomedical equipment and materials customization method based on the diagnosis of biofunctionality of photoreceptor cells, by performing ophthalmic tests of users chromatic vision, in an interactive and non-invasive way, in the “Integrated Cabin for Vision Clinical Analysis” equipment adapted to the different ergonomic conditions and patients health situations, including elderly users, people with temporary or permanent disabilities, adults or children. The method consists of various activities that serve to diagnose the biofunctionality of retinal photoreceptor cells (L, M and S cones) and use biometric data obtained in multimedia eye´s  neural network (optical) to implement a function associated with user’s retinal biofunctionality. The invention has application in the production of customized materials (products) based on the chromatic visual ability of its end users and as telemedicine support in ophthalmology .

Innovative aspects & main advantages

The present invention relates to a novel biomedical device “Integrated Cabin for Vision Clinical Analysis” and to a method of customization of ophthalmologic color vision testing, in an interactive and non-invasive manner. Instead of the usual color perception tests based on the ordering of colored stones, in this invention computational tests of chromatic vision are used in order to identify the preferred color coordinates of each personalized user, in multimedia output.
The method contributes to the follow-up of eye health through the early diagnosis of visual diseases and disabilities, which can be useful for the prevention of avoidable blindness.
