20210188513 · 2021-06-24 ·

The present invention is related to a contact lens package with a heat sealable multilayer packaging lidstock formed from: a support layer and a peelable seal layer made from a polymer blend, such polymer blend formed from a material: from 40 to 85% by weight of one or more first amorphous cyclic olefin polymer(s) characterized by a glass transition temperature of at least 120° C. from 10 to 55% by weight of one or more second amorphous cyclic olefin polymer(s) characterized by a glass transition temperature of less than 120° C., and from 0.5 to 15% by weight, preferably 0.5 to 10% by weight of at least one elastomeric copolymer comprising at least one polymerized monovinylarene and at least one polymerized acyclic olefin

WETTABLE SILICONE HYDROGEL CONTACT LENSES

The invention relates to an ophthalmic product which comprises a sealed and autoclave-sterilized lens package including (1) a post-autoclave packaging solution containing a polymeric surfactant having an HLB value of from about 11 to about 16 and a Mn of from about 800 to about 20,000 Daltons and (2) a readily-usable silicone hydrogel (SiHy) contact lens immersed in the packaging solution. The readily-usable SiHy contact lens comprises the polymeric surfactant thereon providing an excellent wettability to the readily-usable SiHy contact lens directly out of the lens package, and also the leachable polymeric surfactant which is physically distributed in the polymer matrix of the SiHy contact lens and can be released to the eye of a patient for at least 7 days of daily wear and to replenish the lens surface-bound polymeric surfactant to provide sustainable wettabilities to the contact lens and the eye.

Method for packaging a spectacle lens

Contact lens package kit with recycling fastener

A contact lens package kit is described that includes a contact lens packages, wherein each contact lens package 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 material (or other recyclable material) and includes a substantially planar surface surrounding the cavity to provide a sealing surface for the sealing member. The kit also includes at least one fastener configured to retain a plurality of base members from each of the contact lens packages after the contact lens is removed from the cavity. A recyclable thermoplastic contact lens assembly is also described, that includes empty contact lens packages attached to a fastener. A method to recycle used contact lens packages, such as curbside recycling, is further described that uses the fastener, and the fastener itself is also described.

Packaging container of a contact lens

A packaging container (1) for a contact lens comprises a shell (2). The shell (2) comprises a cavity (10) having a drop-shaped perimeter (12), and a flange (20) having a flat upper surface (22) extending around the drop-shaped perimeter (12) of the cavity (10) in an upper surface plane (24). The cavity (10) comprises a bowl portion (30) including an at least partially spherical section (32) for accommodating the contact lens, and a chamfer portion (40) surrounding the bowl portion (30). The chamfer portion (40) is arranged between the bowl portion (30) and the drop-shaped perimeter (12) of the cavity (10) and includes a tapered outlet section (42) forming a tip towards the flange (20) to facilitate removal of the contact lens from the cavity (10).
