Patient interface for ophthalmologic diagnostic and interventional procedures
First Claim
1. A method for intercoupling an ophthalmologic interventional system to an eye of a patient via a patient interface system, the patient interface system comprising a top portion and a bottom portion, the bottom portion having a hollow reservoir housing defining an interior volume and having proximal and distal ends, the top portion having proximal and distal ends and an optical element, the optical element occupying a portion of the interior volume defined by the hollow reservoir, the method comprising:
- a. removably and sealably coupling the distal end of the bottom portion to the eye of the patient;
b. mechanically interfacing the proximal end of the top portion with the interventional system;
c. coupling the top portion with the bottom portion while keeping an open access between the top portion and the bottom portion to provide access to the interior volume for transporting liquids or gases in or out of the interior volume;
d. forming a liquid layer within the interior volume above the eye; and
e. applying one or more loads to the liquid layer, such that the liquid layer is positioned within the interior volume and is located between the optical element and the eye.
