SUB-NANOSECOND LASER SURGERY SYSTEM UTILIZING MULTIPLE PULSED LASER BEAMS

摘要

A system for laser ophthalmic surgery includes: a single laser source, under the operative control of a controller, configured to alternatively deliver a first treatment laser beam and a second treatment laser beam. The first treatment laser beam has a pulse energy of 10 to 500 µJ. The second pulsed laser beam has a second pulse energy of about 0.1 to 10 µJ, lower than the first treatment laser beam. An optical system focuses the first treatment laser beam to a first focal spot and directs the first focal spot in a first treatment pattern into a first intraocular target. The optical system also focuses the second treatment laser beam to a second focal spot and direct the second focal spot in a second treatment pattern into a second intraocular target. The first intraocular target and second intraocular target are different.
