Example

[0019]The present invention provides a packaging system for the storage of ophthalmic devices intended for direct contact with body tissue or body fluid. As used herein, the term “ophthalmic device” refers to devices that reside in or on the eye. These lenses can provide optical correction, wound care, drug delivery, diagnostic functionality or cosmetic enhancement or effect or a combination of these properties. Representative examples of such devices include, but are not limited to, soft contact lenses, e.g., a soft, hydrogel lens; soft, non-hydrogel lens and the like, hard contact lenses, e.g., a hard, gas permeable lens material and the like, intraocular lenses, overlay lenses, ocular inserts, optical inserts and the like. As is understood by one skilled in the art, a lens is considered to be “soft” if it can be folded back upon itself without breaking. Any material known to produce an ophthalmic device including a contact lens can be used herein.

Abstract

A packaging system for the storage of an ophthalmic device, such as a hydrogel contact lens, employs an aqueous packaging solution including a nonionic, nonpolymeric polyol and a nonionic polymeric conditioning agent. Preferably, the solution has an osmolality of at least about 200 mOsm/kg, a pH of about 6 to about 8 and is heat sterilized.

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]The present invention generally relates to packaging solutions for ophthalmic devices such as contact lenses.[0003]2. Description of Related Art[0004]Blister-packs and glass vials are typically used to individually package each soft contact lens for sale to a customer. Saline or deionized water is commonly used to store the lens in the blister-packs, as mentioned in various patents related to the packaging or manufacturing of contact lenses. Because lens material may tend to stick to itself and to the lens package, packaging solutions for blister-packs have sometimes been formulated to reduce or eliminate lens folding and sticking. For this reason, polyvinyl alcohol (PVA) has been used in contact lens packaging solutions. Additionally, U.S. Pat. No. 6,440,366 discloses contact lens packaging solutions comprising polyethylene oxide (PEO) / polypropylene oxide (PPO) block copolymers, especially poloxamers or poloxamines.[0005]It h...
