A laser delivery system for ophthalmic surgery includes a laser engine, configured to generate a laser beam, an optical block, to receive the laser beam generated by the laser engine and to precompensate an aberration of the laser beam, and an XY scanner, to receive, directly or indirectly, the precompensated laser beam outputted by the optical block and to scan the laser beam in a direction essentially transverse to an optical axis of the laser delivery system.
