摘要：
According to an exemplary embodiment, a process for coupling a mechanicalinterface unit (34) to a suction-ring unit (16) retained on an eye by suctionforceincludes a step of relative approximating of the interface unit to the suction-ringunit in an axial direction as far as a first, predetermined relative positionof thetwo components, which is preferentially detected by suitable sensorics. Whenthe first relative position is attained, the evacuation is begun of a suctionchamber(42) formed between the interface unit, the suction-ring unit and the surfaceof the eye, whereby the partial vacuum generated establishes in the suctionchamber a contact between the surface of the eye and an applanation plate (40)retained on the interface unit, or enlarges a region of existing contact. Theaspirating of the eye onto the applanation plate prevents compression loadsandshear loads on the eye such as normally cannot be avoided when impressing theplate onto the eye.
