A flexible head section having two (2) arms with each arm having a distal end and a proximal end, with the distal ends of the arms spaced apart forming a gap there-between at a distal tip section. A flexible flange material envelops and encloses the two arms and the gap and extends around a periphery of the flexible head section. A flexible diaphragm is attached to and extends between the two arms to provide a generally spoon-shaped flexible head section. The flexible head section is linked to the compressible handle section with the linkage being configured such that upon compression of the handle section the arms articulate with respect to each other thereby causing narrowing of the flexible head section to allow for insertion into the orbit and positioning between soft tissue and bone while the flexible diaphragm remains in sufficient tension to not obstruct the view of the operator into the orbit. When compression is released the flexible diaphragm develops sufficient tension and rigidity for applying sufficient force to retract the orbital contents of a patient to allow access to orbital walls.
