1. Membrane forceps for performing an ILM (internal limiting membrane) or ERM (epiretinal membrane) peel procedure; comprising: a handle;a tube extending from the handle; andforceps jaws extending from the tube, the forceps jaws being configured to grasp an ILM or ERM between two opposing grip faces configured to abut each other when the forceps jaws are closed, the forceps jaws also comprising an outer surface, external to the grip faces, having a series of ridges, the series of ridges being structurally configured to aid in scraping the ILM or ERM and gaining an edge of the ILM or ERM;wherein the series of ridges are disposed substantially parallel to leading edges at distal-most ends of the forceps jaws;wherein the series of ridges comprise surface features having a peak to valley height within a range of about 3-40 microns; andwherein the outer surface is angled relative to a longitudinal axis of the tube at an angle having a value between about 25 degrees and 65 degrees to lie substantially parallel to tissue within an eye that is to be scraped when the membrane forceps is in the eye. 2. The membrane forceps of claim 1, wherein the leading edges lie in a plane substantially perpendicular to the longitudinal axis of the tube. 3. The membrane forceps of claim 1, wherein the forceps jaws comprise a first jaw and a second jaw, the first jaw comprising a leading edge, of the leading edges, extending obliquely relative to the longitudinal axis of the tube extending between the first and second jaws. 4. The membrane forceps of claim 1, wherein the series of ridges are substantially parallel to each other. 5. The membrane forceps of claim 1, wherein the series of ridges comprise an array of points extending away from the outer surface. 6. The membrane forceps of claim 5, wherein the series of ridges comprise an array of points extending away from the outer surface in a knurl pattern. 7. The membrane forceps of claim 6, wherein the knurl pattern is a diamond-shaped knurl pattern. 8. The membrane forceps of claim 1, wherein the forceps jaws comprise a first jaw and a second jaw, each of the first and second jaws comprising a leg and a bend that is made in an oblique direction relative to the longitudinal axis of the tube extending between the first and second jaws. 9. The membrane forceps of claim 1, wherein the forceps jaws are configured to be closed by forward motion of the tube over legs of the forceps jaws. 10. The membrane forceps of claim 1, wherein at least one of the series of ridges forms a distal most line of the forceps opposite the handle. 11. The membrane forceps of claim 1, wherein the outer surface extends in a proximal direction from the leading edge. 12. The membrane forceps of claim 1, wherein the series of ridges are a series of rows, each having an array of points extending away from the outer surface. 13. The membrane forceps of claim 1, wherein the first and second jaws are asymmetrical.
