CONTACT LENS PACKAGES AND METHODS OF USE
A blister package for a contact lens includes a base sheet and a sealing sheet. Either the base sheet or the sealing sheet includes a bowl, and the other sheet includes a dome and a sealing surface. The dome has a radius of curvature of about 13 mm to 19 mm and a height of less than 7 mm relative to the sealing surface. The dome is configured to protrude into the bowl to form a cavity. Related methods are also described.
CATIONIC CONTACT LENS
A cationic contact lens is described as well as methods of manufacturing the same. The cationic contact lens includes a polymeric lens body that is the reaction product of a polymerizable composition that includes at least one siloxane, at least one nonionic hydrophilic monomer and at least one acyclic tertiary amine monomer. The cationic contact lens can be an unworn sterile silicone hydrogel contact lens. The contact lens is capable of substantially linear release of a releasable anionic agent and the at least one acyclic tertiary amine monomer facilitates uptake and/or sustained release of the releasable anionic agent by the polymeric lens body. The contact lens can be present in a sealed contact lens package. The sealed contact lens package can include at least a) a base member having a cavity; b) a contact lens packaging solution in the cavity; c) a unworn sterile contact lens immersed in the contact lens packaging solution in the cavity with the releasable anionic agent present; and d) a cover that forms a liquid-tight seal with the base member.
OLEIC ACID-RELEASING CONTACT LENS
An oleic acid-releasing contact lens is described as well as method of manufacturing the same. The oleic acid-releasing contact lens contains oleic acid releasably adhered to the polymeric lens body, and releases from 2 μg to 25 μg oleic acid after 1 hour in a release media. The oleic acid-releasing contact lens can be comfortably worn by a symptomatic contact lens wearer, and can increase the duration of comfortable lens wearing time and/or reduce lens awareness events in a symptomatic contact lens wearer.
Contact lens containing photosensitive chromophore and package therefor
Provided is a contact lens system that comprises: a contact lens containing a photosensitive chromophore and a package surrounding the contact lens. The photosensitive chromophore has at least one active wavelength between 250 and 400 nanometers and at least one active wavelength between 400 and 450 nanometers. The package has a transmittance of no more than 99 percent at each active wavelength.
Contact lens blister package, base member for a contact lens blister, sealing member for a contact lens blister and related methods
A contact lens blister package 1 includes (i) a cavity 4 for storing a contact lens 20 and (ii) charging circuitry 3 configured to charge an electronic device 22 forming part of a contact lens 20 stored in said cavity 4. Related methods are also described.
Crosslinked polymeric network and use thereof
A crosslinked polymeric network is disclosed. The crosslinked polymeric network comprises a reaction product of a first glycosaminoglycan, a second glycosaminoglycan, and a crosslinking agent, wherein the first glycosaminoglycan is different than the second glycosaminoglycan.
Contact Lens Dispenser
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.
Blister Package For Contact Lens
A blister package for a contact lens is provided. A deformable slider supporting a lens is movable via pull-tab or hinge to lift the contact lens out of a lens well. The deformable slider can include a hinge connected to a flexible peel-away top of the blister package or connected to a pull tab that can be pulled to pull taut the deformable slider. A blister package is also provided that includes a hinged shell having a lateral opening opposite the hinge, and a deformable slider that is folded over onto itself and seals both a top chamber and a bottom chamber. By pulling a tongue of the deformable slider, which extends from the lateral opening, the deformable slider can be removed from the closed shell and the closed shell can be opened enabling access to the contact lens.

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.
CONTACT LENS BLISTER PACKAGES AND METHODS FOR RECYCLING SAME
Contact lens packages are provided and each includes a base member having a cavity and a sealing member coupled to the base member. An unworn contact lens is provided in a packaging solution within the sealed cavity. The base member is a thermoplastic or other recyclable material. The base member includes at least one connecting member that can be an interlocking feature and/or a stackable feature. The connecting member is configured to connect to the connecting member of another base member, after the contact lenses are removed from the cavities. A recyclable thermoplastic contact lens assembly is also provided that includes empty contact lens package base members stacked and connected together. A method of manufacturing contact lens packages and a method to recycle used contact lens package base members, such as by curbside recycling, are also provided.
