Abstract
A surgical tool for eye surgery that utilizes a stiffening sleeve and employs a needle of extendible reach. The reach off the needle into the eye is dynamically adjustable by forcible interaction between the stiffening sleeve and a cannula at an outer location of a patient's eye. An end of the tool may retract to facilitate extension of the needle for added reach. Additionally, the sleeve may be further independently retracted for even greater reach of the needle implement toward a surgical site within the eye of the patient.
