Abstract

A contact lens insertion device includes a syringe having a barrel and a piston slidably disposed within the barrel. The barrel is adapted for receiving a fluid which is drawn into the barrel and dispensed from the barrel through operation of the piston. A cup is attached to the syringe. The cup includes a concave surface adapted to receive a contact lens therein. The cup further includes a chamber in fluid communication with the syringe barrel. The concave surface of the cup includes an aperture in communication with the chamber, such that fluid or gel flows from the barrel through the chamber and cup aperture upon actuation of the piston to force the fluid or the gel to flow out of the cup aperture to thereby eject the contact lens from the cup.

Claims

1. A contact lens insertion device comprising:

a syringe including a barrel and a piston slidably disposed within said barrel to alternately draw fluid within said barrel and evacuate fluid from said barrel;

said fluid is selected from the group consisting of water, a saline solution, a balanced salt solution, and a gel;

a cup attached to said syringe, said cup including a concave surface adapted to receive a contact lens therein, a contact lens being retained within said cup by surface tension created by said fluid; and

said cup further including a chamber in fluid communication with said barrel, said concave surface of said cup including a plurality of apertures in fluid communication with said chamber, such that upon actuation of said piston to evacuate fluid from said barrel of said syringe, fluid is expelled from said plurality of apertures to overcome the surface tension retaining a contact lens on said concave surface and thereby eject a contact lens disposed on said concave surface of said cup.
