A microsurgical system with an integrated substance chamber is provided herein for delivering substance (e.g., a drug, retina patch, dye, etc.) to a surgical site through a tool component of the microsurgical instrument, such as a tissue removal component. The system may include a tissue removal handpiece having a tissue cutter disposed at a distal end. The system may further include a first fluid conduit and a second fluid conduit. The first fluid conduit may couple a fluidics subsystem to the tissue removal handpiece to permit removal of cut tissue. The second fluid conduit may couple a substance chamber to the tissue removal handpiece. The system may additionally include a control system that enables or facilitates selective control of fluid through the tissue removal handpiece to introduce substance from the substance chamber to a surgical site through a port in the tissue cutter.
