Title:
PATIENT INTERFACE FOR OPHTHALMIC SURGERY
Document Type and Number:
WIPO Patent Application WO/2019/116173
Kind Code:
A3
Abstract:
In certain embodiments, a patient interface apparatus for ophthalmic surgery comprises an annular member and an evacuation conduit. The annular member has an outer side, an inner side, a distal side, and a proximal side. The inner side defines an opening that allows for a laser beam to reach a treatment region of an eye free from reflection or refraction. The proximal side has a contact surface shaped to affix to a surface of the eye, and a groove that defines a suction chamber with the surface of the eye. The evacuation conduit is capable of fluid communication with the suction chamber, and conducts fluid away from the suction chamber to affix the contact surface to the surface of the eye.
