Abstract

Abstract A device for placing a contact lens in and recovering it from the human eye comprises an oval loop adapted to be placed against the eyelids and to hold them open against blinking. A handle is provided at one end to facilitate manipulating the loop. A resilient wire filament extends from one end of the loop to the center and it carries a knob or a suction cup offset outwardly from the plane of the loop. The knob is adapted with the aid of a wetting agent to support a lens to be placed in the eye. The suction cup is used when it is desired to recover a lens from the eye. Alternatively, the suction cup may be supported directly on the knob. In either case, the knob or suction cup is moved toward the eye with a finger against the resilient tension of the wire filament until either the lens contacts the eye ball or the suction cup contacts a lens in the eye, whereupon it is released leaving the lens in the eye or removing it from the eye as the case may be. When blinking is not a problem, a simplified form of the invention is the form of a bent rod having a handle at one end and a knob or suction cup at the other end.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 84 words
A contact lens manipulator comprising a rigid open oval loop of a size to fit a human eyeball socket, a handle connected to and extending to one side of the loop, a resilient elongated cantilevered filament, extending over the plane of said loop, having one end connected to the loop and the other end connected to a member, said filament holding the member offset from the plane of the loop, said member having an end thereof facing the loop, for holding a contact lens.
Claim 2
Dependent Claim 84 words
A contact lens manipulator comprising a rigid open oval loop of a size to fit a human eyeball socket, a handle connected to and extending to one side of the loop, a resilient elongated cantilevered filament, extending over the plane of said loop, having one end connected to the loop and the other end connected to a member, said filament holding the member offset from the plane of the loop, said member having an end thereof facing the loop, for holding a contact lens.
Claim 3
Dependent Claim 28 words
A contact lens manipulator as defined by claim 1 in which the member is a knob for supporting a contact lens with the aid of a wetting agent.
Claim 4
Dependent Claim 25 words
A contact lens manipulator as defined by claim 2 in which the knob has a socket to frictionally receive the stem of a suction cup.
Claim 5
Dependent Claim 31 words
A Contact lens manipulator as defined by claim 2 in which the member comprises a suction cup having a stem and the knob comprises a socket for frictionally engaging the stem.
Claim 6
Dependent Claim 17 words
A contact lens manipulator as defined by claim 1 in which the member is a suction cup.
Claim 7
Dependent Claim 27 words
A contact lens manipulator as defined by claim 1 in which the oval loop is of a rigid plastic material having a low index of specific heat.
Claim 8
Dependent Claim 47 words
A contact lens manipulator as defined in claim 1 comprising a knob having an annular lip adapted to releasably support a contact lens with the aid of a wetting agent, said knob having a socket, and a suction cup having a stem frictionally engaged in the socket.
Claim 9
Dependent Claim 26 words
A contact lens manipulator as defined by claim 7 in which the annular lip and the socket are disposed on the same side of the knob.
Claim 10
Dependent Claim 19 words
A contact lens manipulator as defined by claim 8 in which the annular lip is concentric with the socket.
