  • Patent number: 4123098
    Abstract: This disclosure relates to a contact lens insertion and retraction device which is especially useful for either inserting or retracting a soft contact lens, onto or from the surface of a person's eye. This device utilizes a flexible bulb member, in cooperative combination with an attached tubular-shaped member, for supplying negative (suction) or positive (exhaust) pressure on a contact lens holder portion that is attached to the open or other end of the tubular-shaped member and thereby connected to the flexible bulb member. During the operation of removing the contact lens from the eye, a negative pressure or suction is applied to the contact lens from the contact lens holder portion by squeezing the flexible bulb member. The flexible bulb member also supplies an exhaust pressure on the contact lens by means of inserting the contact lens onto the eye. The contact lens holder portion is removable for asepticizing.
