System (1) for 3d characterization of the mechanical response of the cornea (2), comprising a dynamic topoptic topographic device (14), whose capture means (15) of images are phenoptics with multiview processing, and where the processing means (16) comprises registration, recognition and triangulation of views, a deformation device (17) of the cornea (2), by constant air pressure (10), and means (13) of computation and characterization of the mechanical behavior of the cornea (2). Measurement procedure with system (1) of 3d characterization comprising the previous obtaining of an expert model (7) based on the biomechanical modeling of multiple corneas, and the characterization of the topographic profile (18) of the cornea (2), application of air pressure (10), characterization of the topographic profile (18) during the deformation, storage and processing (19) of obtained images, obtaining the biomechanical profile (20) of the cornea, and obtaining (21) of its stress-strain curve .
