Patent ID: 7628488

Claim:
A method of orienting the eye of a patient to help prevent the eye from moving in a manner that would interfere with treatment being carried out by an ophthalmologic treatment device, the method comprising the steps of: projecting a fixation mark to be displayed in the field of vision of the eye to be treated; allowing the patient to orient the eye to be treated on this fixation mark through foveal fixation; and moving the fixation mark in the field of vision of the patient during the treatment being carried out by the ophthalmologic treatment device; wherein the movement of the fixation mark is used to position the eye in a specific manner so that (a) the patient can easily follow the fixation mark and (b) the movement of the fixation mark makes the eye less likely to move in a manner that would interfere with the treatment being carried out by the ophthalmologic treatment device.
