    摘要: The invention refers to A system (10) for registering and tracking the position of a person's eye, in particular for refractive ophthalmic surgery. According to the invention, the system is designed such that eye images containing at least the iris and the pupil of the eye are made at a first wavelength of light and that eye images containing scleral blood vessels are made at a different second wavelength of light. The invention furthermore refers to a corresponding method for registering and tracking the position of a person's eye.
