The present invention is directed to a method for intercoupling an ophthalmologic interventional system to an eye of a patient, comprising: (i) providing a patient contact interface comprising: a. a hollow reservoir housing defining an interior volume and having proximal and distal ends, wherein the distal end comprises an eye interface surface configured to be removably and sealably coupled to the eye of the patient, and wherein the proximal end is configured to be mechanically interfaced with the interventional system in a manner that allows for open access to the interior volume for transporting liquids or gases in or out of the interior volume； and b. an optical element fixedly coupled to the hollow reservoir housing and occupying a portion of the interior volume； wherein the interior volume of the reservoir housing is configured to accommodate a liquid layer formed within the interior volume of the reservoir housing and positioned, via one or more loads that include gravitational loads, between the optical element and the eye, wherein liquid can be added to and removed from the liquid layer by direct pouring； (ii) removably and sealably coupling the distal end of the housing to the eye of the patient； (iii) mechanically interfacing the proximal end of the housing with the interventional system； and (iv) adding liquid to and/or removing liquid from the liquid layer by direct pouring.
