Abstract
The disclosure provides an ophthalmic surgical microscope including an optical axis. The ophthalmic surgical microscope also includes at least one light source configured to provide illumination having a wavelength range between 575 nm and 625 nm. The ophthalmic surgical microscope further includes a control device for directing the illumination at an acute angle relative to the optical axis of the microscope.
