1. A system for intercoupling an ophthalmologic interventional system to an eye of a patient, comprising: a. a hollow reservoir housing defining an interior volume and having proximal and distal ends, wherein the distal end comprises a 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;b. an optical element fixedly coupled to the hollow reservoir housing and occupying a portion of the interior volume; andc. 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 the eye interface surface comprises a compliant circumferential seal member, and the seal member comprises two circumferential layers with a vacuum space interposed between the two layers. 2. The system of claim 1, wherein the hollow reservoir housing comprises two parts that may be removably coupled to each other. 3. The system of claim 2, wherein the two parts are removably coupled to each other using a configuration selected from the group consisting of: a vacuum coupling interface, an interference fit interface, an electromagnetic coupling interface, a manually-actuated mechanical interface, and an electromechanically-actuated mechanical interface. 4. The system of claim 1, wherein the liquid layer comprises about 2 cubic centimeters in volume. 5. The system of claim 2, wherein the hollow reservoir housing comprises a proximal part and a distal part, and wherein the optical element is fixedly coupled to the distal part. 6. The system of claim 2, wherein the hollow reservoir housing comprises a proximal part and a distal part, and wherein the optical element is fixedly coupled to the proximal part. 7. The system of claim 1, wherein the optical element comprises a lens having proximal and distal surfaces. 8. The system of claim 7, wherein the distal surface of the lens is a convex surface. 9. The system of claim 1, further comprising a vacuum loading device configured to apply a vacuum load into the vacuum space. 10. The system of claim 9, wherein the vacuum loading device is configured to apply a vacuum load of between about 200 mm of mercury and about 600 mm of mercury. 11. The system of claim 1, wherein at least one of the circumferential layers has a tapered cross section. 12. The system of claim 1, wherein at least one of the circumferential layers comprises a shape that is at least partially spherical. 13. The system of claim 1, wherein the liquid layer comprises a material selected from: water, saline, oil, viscoelastic gel, and perfluorocarbon liquid. 14. The system of claim 1, wherein the liquid layer is in immediate contact with the optical element.
