An ophthalmic system for visualization of interactions between ocular matter and a probe tip of a probe within or in contact with an ocular space of an eye includes: a visualization tool having a field of view that includes at least a portion of the ocular space of the eye where the probe tip interfaces with the ocular matter; and a stroboscopic illumination source configured to stroboscopically illuminate at least the portion of the field of view at an illumination frequency. A method of operating a stroboscopic illumination source during an ophthalmic surgical procedure includes: identifying an illumination source type of the stroboscopic illumination source; identifying a probe type; identifying a first procedure trigger; and operating the stroboscopic illumination source based on the probe type, the illumination source type, and the first procedure trigger.

Ophthalmic surgical microscope with stroboscopic illumination

Methods are disclosed for operating a laser. Such methods may comprise operating the laser to emit electromagnetic energy in an infrared range in pulses with a pulse duration of greater than 1 ns. The wavelength of infrared electromagnetic energy may be in a range of about 2.6μ to about 3.3μ or about 1.8μ to about 2.1μ. The pulses may have a pulse energy selected to deliver an energy density of 2,500 J/cmor greater. The laser electromagnetic energy may be delivered for a medical application, such as cataract surgery to break apart a cataractous lens by photodisruption.

Efficient lasers for tissue disruption

Systems and methods are disclosed for a surgical laser system with illumination. In some embodiments, a laser system comprises a surgical laser and an illumination source having their outputs combined into a fiber-optic cable and directed by the fiber-optic cable to a target surface. The illuminating visible light may be continuous and/or in pulses. Surgical laser pulses and illumination pulses may be synchronized for a stroboscopic effect. The laser system may also monitor laser electromagnetic radiation that is returned back through the fiber-optic cable.
