Abstract

A planning device for a scanning pattern of a closed structure in an eye, an ophthalmic laser treatment device and corresponding methods including a scanning pattern of a closed structure in a tissue of a patient's eye in a single-pass method for the control of an ophthalmic laser treatment device, in which a starting point of the macroscopic scanning pattern which contains the scanning pattern is arranged in a region in which the angle between a direction of progress of the macroscopic scanning pattern and a direction of a maximum offset caused by movements of the eye relative to the ophthalmic laser treatment device is minimal, or in a region of a minimum change in the macroscopic scanning pattern (n the z-direction per unit of time, or in a region in which a direction of progress of the macroscopic scanning pattern is parallel to a direction of maximum offset.
