Abstract
An improved, asynchronous method of operating a microsurgical instrument, such as a vitrectomy probe. The instrument includes a port for receiving tissue and an inner cutting member. A flow of tissue is induced into the port with a vacuum source. The port is at least partially occluded with the tissue. The occlusion is detected, and the inner cutting member is actuated to close the port and cut the tissue.
