1. ) A multiple target ophthalmic surgery apparatus comprising:
- an instrument having a handle that is dimensioned to be held and manipulated by a single hand of a user of the instrument and a rigid tubular tip that extends from the handle to a distal end of the tip that is dimensioned for insertion into an eye in performing ophthalmic surgery procedures;
at least one primary optic fiber having a length that extends from the instrument handle to an end of the at least one primary optic fiber, the length of the at least one primary optic fiber enabling the instrument handle to move freely relative to the end of the at least one primary optic fiber;
a light source connector on the end of the at least one primary optic fiber, the light source connector being connectable to a separate light source to transmit light from the light source through the at least one primary optic fiber to the instrument handle; and
,a plurality of additional optic fibers having lengths that extend through the instrument tip to distal ends of the plurality of additional optic fibers having distal end surfaces adjacent the distal end of the instrument tip, the distal end surfaces of the plurality of additional optic fibers facing in a plurality of different directions to project light transmitted through the plurality of additional optic fibers in a plurality of different directions.

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.
