High intensity focused ultrasound device with a concave segment shaped transducer for eye treatment

A device to treat an ocular pathology comprising

• at least one eye ring wherein a proximal end of said eye ring is configured to be applied onto an eye globe and
• an ultrasound beam generator for generating high intensity focused ultrasound, said ultrasound beam generator being fixed on a distal end of the eye ring, and wherein the ultrasound beam generator comprises at least two transducers wherein each transducer is a flat segment having a rectangular profile that extends parallel to the proximal and distal edges of the eye ring, and at least two focusing acoustic elements extending under a respective transducer, where each focusing acoustic element presents a cylindrical segment shape configured to be tuned towards the eye globe, the transducers being distributed circumferentially,
• wherein the device is configured to treat the whole circumference of the eye in only one step,
• wherein the ultrasound beam generator comprises a standing crown holding the at least two transducers, said standing crown being fixed on the distal end of the eye ring in such a way that the transducers extend toward the revolution axis of said eye ring, and
• wherein an external annular flange comprises a concave profile having a radius of curvature configured to be fit to curvature of the eye globe.
