Abstract
A method of cleaning contaminants from a contact lens is disclosed. The method comprises the steps of positioning a contact lens and an adsorbent so that the adsorbent is disposed between the contact lens and an electric current source, immersing the contact lens, the adsorbent, and the current source in a saline solution, then applying an electric current from the current source through the adsorbent and the contact lens so that contaminants carried by the contact lens migrate to the adsorbent. Additionally, a disposable, arcuate-shaped adsorbent article conformable to and matable with the convex and concave surfaces of the contact lens is also disclosed.
Claims20
A method of removing contaminants from a contact lens, comprising:
- (a) positioning the contact lens, a first adsorbent, and an electric current source configured so that said adsorbent is disposed between the contact lens and the electric current source and so that the current passes through said lens, said adsorbent including a free chemical substituent having a affinity for protein;
- (b) immersing the contact lens, the adsorbent, and the electric current source so disposed in a saline solution;
- and then
- (c) applying an electric current from the current source through the adsorbent and the contact lens so that contaminants carried by the contact lens migrate to the adsorbent.
A method of removing contaminants from a contact lens, comprising:
- (a) positioning the contact lens, a first adsorbent, and an electric current source configured so that said adsorbent is disposed between the contact lens and the electric current source and so that the current passes through said lens, said adsorbent being formed from a nitrocellulose membrane;
- (b) immersing the contact lens, the adsorbent, and the electric current source so disposed in a saline solution;
- and then
- (c) applying an electric current from the current source through the adsorbent and the contact lens so that contaminants carried by the contact lens migrate to the adsorbent.
