Abstract

A multiple target ophthalmic surgery instrument is comprised of a single primary optic fiber that transmits laser light to the instrument, and a plurality of additional optic fibers that receive the laser light from the primary optic fiber and project the laser light as a plurality of beams from the plurality of additional optic fibers. In this manner, the instrument splits the single laser light beam received from a single laser light source into the multiple of laser beams and targets the multiple laser beams at multiple spots of a surgical site in the eye.
