Patent number: 7395575Abstract: A limited use apparatus for treating contact lenses is disclosed. The apparatus comprises a case having a body and a left and right cover which are joinable to form chambers for receiving the lenses. Each of the chambers has an operative face for receiving the lens. A reactive layer is provided on a portion of each operative face. The operative faces and the reactive layers are dimensioned and arranged whereby the reactive layers come into engagement with respective optical surfaces of a lens positioned there-between when the cover and body are joined together.Type: GrantFiled: June 1, 2007Date of Patent: July 8, 2008Assignee: Isoclear, Inc.Inventors: Nicholas Webb, John Zeis, Scott Castanon

Patent number: 6662397Abstract: A self-contained apparatus for cleaning contact lenses comprising a deformable, non-abrasive material having an enzyme enriched layer for contact with the optical surfaces of the lenses. While in contact with the optical surfaces, the contaminants on the lens surfaces are enzymatically removed. Upon separation of the lenses and the deformable material, substantially all of the enzymes are retained on the deformable material, largely eliminating the need to perform additional operations to inactivate the enzymes or otherwise rid the lenses of residual enzymatic matter.Type: GrantFiled: July 27, 2001Date of Patent: December 16, 2003Assignee: IsoCLEAR, Inc.Inventor: Mark L. Pankow

Patent number: 6343399Abstract: A self-contained single-use apparatus for cleaning and hydrating a pair of contact lenses comprises a housing including a pair of hollow snap-lock lens containers in which opposed layers of a deformable relatively hydrophobic reactive material having surfaces arranged for non-abrasive contiguous wetted contact with the optical surfaces of the lenses when the lenses are enclosed in the housings. While in contact with the optical surfaces contaminants in the lenses are attracted to the contacting surfaces of the reactive layers. Upon removal of the lenses the attracted contaminants remain on the contacting surfaces and are disposed of with the housing. The container contains sufficient absorbed liquid for maintaining the lens in a hydrated condition while being treated in the container during the treatment process.Type: GrantFiled: August 21, 2000Date of Patent: February 5, 2002Assignee: IsoClear, Inc.Inventor: Mark L.

Patent number: 5780325Abstract: Isolation regions for a semiconductor layer of a semiconductor-on-insulator substrate are fabricated by forming a patterned implantation mask on the semiconductor layer. The patterned implantation mask includes mask sidewalls. An implantation masking film is formed on the sidewalls of the patterned implantation mask. Ions are implanted into the semiconductor layer, using the patterned implantation layer and the implantation masking film as a mask, to thereby form a doped region in the semiconductor layer. Sidewall spacers are formed on the implantation masking film, opposite the patterned implantation mask. The doped region between the sidewall spacers is etched to thereby define a trench in the semiconductor layer between the sidewall spacers and a doped edge layer in the semiconductor layer which extends from the trench to the implantation masking film. Insulating material is then formed in the trench.Type: GrantFiled: December 11, 1996Date of Patent: July 14, 1998Assignee: Isoclear, Inc.Inventor: Joon-hee Lee

Patent number: 5529678Abstract: A system by which contaminants from and below the surface of contact lenses may be electrokinetically removed. The system includes a protective encasement packet in which a lens is safely protected upon its removal from the eye, through the cleaning procedure, and until the lens is returned to the eye. The system includes also a cleaning assembly in which the lens as encased within the packet is decontaminated. The cleaning assembly includes surfaces positionable to contact the packet and from which electrical charges are transmitted to the lens. Under the influence of the electrical charges, contaminants are drawn off of and from below the surface of the lens.Type: GrantFiled: November 3, 1994Date of Patent: June 25, 1996Assignee: Isoclear, Inc.Inventor: Mark L. Pankow

Patent number: 5439572Abstract: A packet including substance and of a construction by which a lens may be encased and by which the application of treatment procedures to the lens is facilitated. The packet is useful in protecting the lens from possible damage during the period when the lens is separated from the cornea and is being treated. The packet is useful in a lens decontamination system that includes also a cleaning assembly in which the lens as encased within the packet is decontaminated. The packet includes surfaces positionable to contact the packet and through which electrical charges are transmitted to the lens. Under the influence of the electrical charges, contaminants are drawn off of and from below the surface of the lens.Type: GrantFiled: July 12, 1993Date of Patent: August 8, 1995Assignee: Isoclear, Inc.Inventor: Mark L.

Patent number: 5227039Abstract: An apparatus and method by which permeable contact lenses may be cleaned through electrokinetic phenomenon is disclosed. The apparatus includes an receptacle in which a lens is supportively aligned between terminals by a member or members made from a pliant transmission media. As aligned, an electric current will be focused to flow only through the lens in order to efficiently and quickly decontaminate the lens.Type: GrantFiled: December 2, 1991Date of Patent: July 13, 1993Assignee: Isoclear, Inc.Inventor: Mark L.
