Abstract: In certain embodiments, an ophthalmic laser surgical system for treating a floater in a vitreous of an eye includes a floater detection system, a laser device, and a computer. The floater detection system determines the location of the floater in the vitreous of the eye. The laser device directs a laser beam along a laser beam path towards the floater.
