Abstract

An incision and placement marker (100) is used to place incision and positioning marks on the eye as well as to center a vacuum centering guide. A corneal spreader (150) forms pockets in the corneal tissue at the incision site. Clockwise and counter-clockwise glides (240) ease the insertion of clockwise and counter-clockwise dissector blades. A field dissector inspection gauge (400) is provided to check the planarity and concentricity of dissector gauges. Forceps (500) have a space having a predetermined shape to hold an implant at a predetermined acute angle. A kit includes the incision and placement marker (100), corneal spreader (150), glide (240), field dissector inspection gauge (400), and, optionally, the forceps (500). Methods of using the instruments are also provided.
