A preservative-free contact lens treating solution includes (a) about 0.005 to about 2 wt. %, based on the total weight of the preservative-free contact lens treating solution, of hyaluronic acid or a salt thereof; (b) about 0.01 to about 1 wt. %, based on the total weight of the preservative-free contact lens treating solution, of erythritol; (c) one or more nonionic surfactants; (d) sodium chloride, potassium chloride or any combination thereof; and (e) one or more buffers.

A packaging system for storing ophthalmic devices such as contact lenses and methods for packaging such ophthalmic devices with solutions is disclosed. The packaging system contains an unused, ophthalmic device in an aqueous packaging solution comprising tris(hydroxymethyl)aminomethane or a salt thereof; wherein the solution has an osmolality of at least about 200 mOsm/kg and a pH in the range of about 6 to about 9.

Contact lens dispensers are provided including a pens dispenser having an interior and a dispensing end. A delivery screw is provided in the interior of the tubular housing. The delivery screw has a thread pitch and a plurality of contact lenses, one contact lens per pitch. Upon actuation of an actuator, each contact lens moves along the thread by a distance of one pitch and a single contact lens is dispensed from the dispensing end of the tubular housing. A case and disposable foil contact lens cartridge are also provided as a re a case and disposable contact lens foil spool, wherein actuation of push-buttons dispense contact lenses ready for immediate application onto an eye.

This invention relates to comfortable ophthalmic devices and methods of producing such devices by treating unhydrated, polymerized ophthalmic lens with a polymeric wetting agent, wherein the ophthalmic lens formulation does not comprise said wetting agent prior to its polymerization.

An embodiment of the invention is a basket for holding contact lenses. The basket comprises a first basket and a second basket mating members, each basket member includes a basket wall defining a first cavity, a planar flange extending out around the first cavity, a plurality of spaced fingers extending upward circumferentially from the periphery of the cavity, wherein the first basket and second basket mating members having a same structure, wherein the first basket and second basket mating members forming a second cavity when mated for receiving said contact lens, the cavity inhibiting inversion or rolling over of said contact lens when emplaced therein. A tray that comprises a plurality of baskets is another embodiment of the invention. In addition, the invention provides a stack assembly that comprises a plurality of trays each of which comprises a plurality of baskets.

A method of disrupting a bacterial biofilm present on a surface, comprising applying a composition that includes a semi-alkaline protease produced by the fermentation of the fungus Aspergillus melleus (Seaprose) to the bacterial biofilm, wherein application of the composition to the bacterial biofilm disrupts the matrix of the bacterial biofilm.

A contact lens storage and cleansing container including a number of closable contact lens chambers to which contact lens fluid can be fed from a fluid reservoir by means of a pump device via a channel system, and wherein the contact lens storage and cleansing container is suitable for a particularly long storage stability for the fluid being stored in the reservoir, The fluid reservoir can be connected, at the fluid end, by the channel system to an outlet opening via the contact lens chamber or contact lens chambers.

A grafted glycosaminoglycan polymer is disclosed. The grafted glycosaminoglycan polymer comprises a glycosaminoglycan having a polymer backbone and one or more side chains comprising a polyalkylene glycol-containing residue grafted onto the polymer backbone.
