Abstract
Surgical instruments and, particularly, ophthalmic surgical instruments are disclosed. Example surgical instruments include forceps for removal of an internal limiting membrane (ILM). The example forceps may include a textured surface formed at a distal end of the forceps jaws. The textured surface may have a plurality of microposts that operate to increase a coefficient of friction between the ILM and the forceps in order to reduce a normal force, applied by the forceps, needed to engage the ILM.
