Abstract: The present invention relates to a multi-purpose ophthalmological apparatus, comprising first optical means, provided with one or more first mires, and sensing means for acquiring along a first optical path an image comprising said one or more first mires reflected by a patient's eye, characterised in that it comprises separating optical means for separating the first optical path from at least one second optical path, and in that it further comprises second optical means, provided with one or more second mires, located along the first optical path between the separating optical means and the sensing means, whereby said image further comprises said one or more second mires reflected by the patient's eye.

Abstract: The invention relates to a container (1) for forced irrigation, particularly for ocular surgery intervention, comprised of three elements (2, 3, 4), provided side by side, coupled each other along their perimetral edge, so as to realise a first (5) and a second (6) pocket, said pockets (5, 6) being provided with independent substance introduction and withdrawal means (8, 9), contents of the two pockets (5, 6) not being physically in communication each other.

Abstract: The invention concerns an improved tip (1) for oculistic surgery, particularly for the removal of cataract, having a proximal joint end (2) and a distal end (4), contacting the crystalline during the surgical intervention, wherein the distal end (4) contacting a corneal or sclera tissue is coated with an anti-friction treatment, based on carbon and tungsten carbide.

Abstract: This invention relates to an optimization method for driving a piezoelectric actuator by dynamic detection of its electromechanical characteristics, as well as to a device, in particular a phacoemulsifier based thereupon. The piezoelectric actuator includes a voltage driven, two-terminal piezoelectric transducer. The method for detection of its electromechanical characteristics is such that the drive of the transducer is cyclically discontinued in order to detect the characteristic parameters of its free motion by detection of the parameters of the signal generated by the transducer at the ends of the two terminals.
