Abstract (en)

[origin: WO9958047A1] A combination of a confocal scanning laser ophthalmoscope and external laser sources (52, 54) is used for microphotocoagulation of the retina or the measurement of wavefront aberrations of the eye optics. An opto-mechanical linkage device (100) with beamsplitter (56) allows independent positioning of the pivot point (16) of the lasers of a scanning laser ophthalmoscope and the pivot point of non-scanning external laser beams. A similar pivot point location is used to minimize wavefront aberrations and to enable precise focusing of a therapeutic laser beam (52) on the retina. The pivot point of an external diagnostic laser beam (54) is systematically moved across the anatomical pupil when wavefront aberrations are to be measured. One confocal detection pathway of the scanning laser ophthalmoscope is used to localize fiducial landmarks on the retina. A second synchronized detection pathway is used to characterize the spot on the retina that is produced by the external laser beam. External laser beams (52, 54) can be polarized to eliminate specular reflections, and pulsed in anti-aliased fashion with its own confocal detection.
