  • Publication number: 20240264430
    Abstract: A tunable lens includes a soft transparent polymer layer whose shape (optical profile) is dynamically modified by actuation of one or more piezoelectric actuators or shaping/reshaping of a transparent piezoelectric layer with a plurality of actuation zones on it. Through control of the actuation voltage a particular shape corresponding to a desired focal distance is obtained. Thus, spherical or aspherical reshaping of the tunable lens may be accomplished through the transparent piezoelectric layer.

  • Publication number: 20230149155
    Abstract: An apparatus for eye surgery may comprise a nozzle having a delivery lumen, an implant bay coupled to the nozzle, an implant disposed in the implant bay, and an actuator coupled to the implant bay. The actuator may comprise a housing; a bore through the housing; a plunger disposed within the bore; and a compression ring. The plunger can be configured to advance within the bore, thereby advancing the implant from the implant bay through the delivery lumen, and the bore can be configured to compress the compression ring as the plunger moves through the bore. In some embodiments, the bore can be configured to increase compression on the compression ring as the first end of the plunger moves through the bore.
