Abstract
Patterned laser treatment of the retina is provided. A visible alignment pattern having at least two separated spots is projected onto the retina. By triggering a laser subsystem, doses of laser energy are automatically provided to at least two treatment locations coincident with the alignment spots. All of the doses of laser energy may be delivered in less than about 1 second, which is a typical eye fixation time. A scanner can be used to sequentially move an alignment beam from spot to spot on the retina and to move a treatment laser beam from location to location on the retina.
Claims23
A method for laser treatment of tissue of a patient, the method comprising:
- displaying a visible alignment pattern that defines a plurality of separate treatment locations on the tissue;
- and
- triggering a laser subsystem with an operator action to deliver sequential doses of laser energy to at least two of the treatment locations defined by the alignment pattern within a time period of about 1 second.
