Abstract
The invention provides an apparatus and method for scanning, imaging and treating the retina of an eye. The apparatus (10) comprises a source of collimated light (14), a two-dimensional scanning device (16) having two axes of rotation (16a, 16b), wherein the axes of rotation (16a, 16b) are orthogonal and substantially planar, and wherein the source of collimated light (14) and the two-dimensional scanning device (16) combine to provide a two-dimensional collimated light scan from a point source (22). The apparatus (10) further comprises a scan transfer device (18), wherein the scan transfer device (18) has two foci (18a, 18b) and the point source (22) is provided at a first focus point (18a) of the scan transfer device (18) and an eye (12) is accommodated at a second focus point (18b) of the scan transfer device (18), and wherein the scan transfer device (18) transfers the two-dimensional collimated light scan from the point source (22) into the eye (12).
