First Claim
Patent Images
1. An interface for coupling a patient'"'"'s eye to a surgical laser system, the interface comprising:
- an attachment ring configured to overlay the anterior surface of the eye, the attachment ring comprising an inner surface;
a lens cone defining a first plane surface and configured to couple to a delivery tip of the surgical laser such that the delivery tip is positionally referenced to the first plane surface, the lens cone comprising;
an apex ring coupled to the first plane surface, the apex ring comprising a distal end; and
an applanation lens disposed at a distal end of the apex ring and positioned in a second plane surface parallel to the first plane surface such that the delivery tip is positionally referenced to the second plane;
a gripper comprising;
a first receptacle configured to receive the attachment ring;
a gripper portion having an inner surface;
a receiver portion having an inner surface; and
a central orifice configured to receive the lens cone, the gripper stabilizing the relative positions of the lens cone and the attachment ring when the lens cone and attachment ring are received within the gripper; and
a chamber configured to receive a liquid, the chamber formed by the inner surface of the attachment ring, the inner surface of the gripper portion, the inner surface of the receiver portion, and the applanation lens when the lens cone and attachment ring are received within the gripper.
