Abstract: A calibration method for a camera-based measuring device comprises positioning a calibration object simulating an anterior region of the eye on a holder arranged movably in a first direction relative to a camera of the measuring device within a view field of the camera. The first direction is toward and away from the camera substantially along a camera axis. A motorized drive unit, in drive connection with the holder, is firstly controlled to drive the holder, with the calibration object positioned thereon in the camera view field, relative to the camera along the first direction at least once past a position of maximum definition of an image of the calibration object taken by the camera. A ratio between an actual size and an imaging size of the calibration object is determined on the basis of a camera image of the calibration object taken at the position of maximum definition.

Abstract: In certain embodiments, an apparatus for accommodating a computer includes a horizontal platform, docking station, and cable pathway. The horizontal platform can support a medical device. The horizontal platform has an upper surface and a rectangular recessed portion. The docking station is disposed at least partially within the recessed portion, and can connect to either a first or second computer. Each computer has a top surface and can be in an open or closed state. The cable pathway between the medical device and docking station can accommodate cables that connect the medical device to the docking station. The recessed portion can accommodate either the first or second computer when either the first or second computer is connected to the docking station, such that the top surface of the accommodated computer is level with the upper surface of the horizontal platform when the computer is in the closed state.
