Systems and methods for drug delivery to ocular tissue

A device for delivering a medicament to ocular tissue, the device comprising:

• a housing having;
• a needle defining a needle axis;
• a carriage positioned within the housing and coupled to the needle, wherein the carriage is translatable along the needle axis, and wherein the carriage includes a threaded outer surface;
• a nut positioned within the housing and engaged with the threaded outer surface;
• a motor coupled to the nut;
• and
• a controller configured to:
• receive an activation signal;
• and
• cause, in response to the activation signal, the motor to apply a torque to the nut, thereby causing the nut to rotate and causing the carriage and the needle to translate distally along the needle axis.

A device for delivering a medicament to ocular tissue, the device comprising:

• a container configured to contain the medicament;
• a needle in fluid communication with the container, wherein the needle defines a needle axis;
• a collar coupled to the container and the needle, wherein the collar includes a threaded outer surface;
• an eye shield coupled to a distal end of the device, wherein the eye shield includes a contoured surface configured to conform to an outer surface of an eye, and wherein the eye shield is configured to translate along the needle axis relative to the collar;
• and
• a wheel engaged with the threaded outer surface, wherein rotation of the wheel is configured to cause the eye shield to translate along the needle axis.
