Abstract: In certain embodiments, an apparatus is provided for performing a subretinal injection into a subretinal space between a retina and a retinal pigment epithelium of an eye. The apparatus includes an injection needle having a proximal end and a distal end, the distal end configured to be insertable into the subretinal space at a position on a surface of the retina. The apparatus includes a multi-lumen tubing having a distal end coupled to the proximal end of the injection needle and a proximal end coupled to a fluid control unit. The apparatus includes a stabilizer configured to immobilize the injection needle at the position on the surface of the retina. The fluid control unit has a plurality of fluid reservoirs containing a non-treatment solution, a treatment solution, and a working fluid which are injectable into the eye via separate lumens of the multi-lumen tubing.

Abstract: Projection of visible, non-treatment light onto an eye to illuminate specific areas of the surgical field is disclosed herein. A surgical system may include a surgical console; a microscope communicatively coupled to the surgical console; a camera communicatively coupled to the surgical console; and a projector operable to project light onto an eye. The projector may be communicatively coupled to the surgical console. A method for light projection may include collecting information from an eye using a camera; determining the light projection based, at least in part, on the collected information; and projecting visible, non-treatment light onto the eye using a projector.
