Claim Text:
1. A method comprising: fixing a blade of an ophthalmic surgical instrument in a first position relative to an outer sleeve of the ophthalmic surgical instrument wherein the blade is disposed in a blade mount and wherein the blade mount is fixed to an inner handle of the ophthalmic surgical instrument, the inner handle having a pressure mechanism foundation, a distal outer sleeve interface, a proximal outer sleeve interface, an inner handle base, and an actuation control apparatus; indicating a property of the blade to a surgeon by a blade indication signal of the actuation control apparatus; increasing a total contact area between the surgeon's finger tips and the outer sleeve of the ophthalmic surgical instrument by a plurality of grip points of the outer sleeve wherein the outer sleeve has an actuation pin access port, an outer sleeve proximal core, an outer sleeve distal core, and a pressure mechanism distal interface; providing a first resistive force to resist an actuation of an actuation pin of the ophthalmic surgical instrument out from a proximal detent of the outer sleeve wherein the first resistive force is provided by a spring and wherein the spring has a spring constant-of less than 0.01 N/mm; actuating the actuation pin of the ophthalmic surgical instrument out from the proximal detent of the outer sleeve; rotating the inner handle of the ophthalmic surgical instrument in a first direction relative to the outer sleeve; actuating the actuation pin into an actuation channel of the outer sleeve; providing a second resistive force to resist an actuation of the actuation pin along the actuation channel wherein the second resistive force is provided by the spring; actuating the actuation pin along the actuation channel; aligning the actuation pin for an ingress into an intermediate detent of the outer sleeve; rotating the inner handle in a second direction relative to the outer sleeve; providing a first facilitating force to facilitate an actuation of the actuation pin into the intermediate detent wherein the first facilitating force is provided by the spring; actuating the actuation pin into the intermediate detent; fixing the blade in a second position relative to the outer sleeve wherein the blade extends a first distance from a distal end of the outer sleeve and wherein the blade has a first exposed blade width; preventing unintentional movement of the blade during a surgical procedure; positioning the blade at a first angle relative to a plane normal to a portion of a surface of a tissue; penetrating the tissue with the blade positioned at the first angle relative to the plane normal to the portion of the surface of the tissue wherein the blade is configured to make a first surgical incision of the first exposed blade width; identifying a first surgical incision depth by comparing the portion of the surface of the tissue to a first surgical incision guide of the blade wherein the first surgical incision guide of the blade is located 0.25 millimeters from a distal end of the blade; positioning the blade at a second angle relative to the plane normal to the portion of the surface of the tissue to increase a total surface area of the tissue severed by the blade; providing a third resistive force to resist an actuation of the actuation pin out from the intermediate detent wherein the third resistive force is provided by the spring; actuating the actuation pin out from the intermediate detent; aligning the actuation pin for an ingress into a distal detent of the outer sleeve; providing a second facilitating force to facilitate an actuation of the actuation pin into the distal detent wherein the second facilitating force is provided by the spring; actuating the actuation pin into the distal detent; and fixing the blade in a third position relative to the outer sleeve wherein the blade extends a second distance from the distal end of the outer sleeve and wherein the blade has a second exposed blade width.
