Abstract:
The invention relates to a packaging for an ophthalmic lens (100) that comprises a box (200) and a lens holder (300) inside the closed box. The holder includes at least one flexible portion (305) that is bent by the lid (202) of the box when said lid is closed. The portion thus bent bears against a peripheral edge (B) of the lens in order to maintain said lens at a distance from the lid inside the box. A convex face (S1) of the lens in the box is thus protected against any damage.
Abstract:
A vibration-type cleaning device for contact lenses comprises an adaptor that is provided with a support part thereon for supporting a contact lens case and a base that is provided under the bottom of the adaptor. The base is connected with the adapter via a positioning element so that the base can be attached to or detached from the adaptor. The base is provided with a vibrator therein and the vibrator is connected with a power source. Consequently, the vibrator can be driven under the control of a user to vibrate the contact lens solution and the contact lenses in the contact lens case and the cleaning effect of the contact lenses in the contact lens solution can be enhanced through vibration.
Abstract:
A process for cleaning all types of contact lenses by placing each contact lens in individual compartments of a liquid impermeable lens storage container filled with an aqueous medium such as sterile saline or sterile lens cleaning solution, floating the liquid impermeable storage container in an ultrasonic device operating at a frequency of 50-60 Hz and a wattage of 20-117 watts.
Abstract:
A container for storing a silicone hydrogel contact lens in a liquid, having a bowl portion with a radius such that the radius of the lens is from about 85 percent to about 100 percent of the inner surface radius. The bowl portion has an outer section which is defined by a radius larger than the inner surface radius. Furthermore, the bowl portion has a roughness sufficient to maintain capillary attraction of the lens to the bowl portion but preventing adhesion of any portion of the front surface of the lens to the bowl portion.
Abstract:
Storage device for storing contact lenses and contact lens solution including a case defining a reservoir for contact lens solution and a pair of contact lens retaining compartments for retaining contact lenses. The case includes a mechanism for causing a stream of contact lens solution to flow from the reservoir to an exterior of the case (for use when rinsing and/or cleaning the contact lens) and another mechanism for causing the contact lens solution to flow from the reservoir into the compartments (for use when storing the contact lenses in the compartments). These mechanisms can be alternatively enabled depending on the particular use sought for the contact lens solution.
Abstract:
A contact lens package that is reusable as a case to store a contact lens between uses includes a bottom member having a well with an inside generally concave shape, and a wall rising above the well and ending in a top rim defining an opening; a temporary seal comprising a moisture-proof film sealed across the top rim to seal the opening, thus defining a volume within the package, the volume containing a contact lens and contact lens fluid; and a cap secured to the bottom member covering the temporary seal, the cap being removable to give access to the temporary seal and replaceable on the bottom member thereafter to provide storage of the contact lens between uses thereof. The contact lens package and storage case can be used as part of a system having a generally flat base member with two receptacles and indicia identifying one of the receptacles as being for a left eye contact lens package and the other of the receptacles as being for a right eye contact lens package; and a plurality of contact lens packages each comprising: a bottom member configured to be received by one of said receptacles and held securely onto the base; a cap secured to the bottom member to enclose a volume; and a contact lens and contact lens fluid within the volume; wherein the plurality of contact lens packages include a generally equal plural number of packages containing a contact lens to be used in the left eye of a contact lens wearer and packages containing a contact lens to be used in the right eye of a contact lens wearer.

Abstract:
An ophthalmic solution comprising a polyethoxylated glyceride in the range of 0.001 to about 10 percent by weight and a buffer agent. These solutions impart surprising comfort and wearability to contact lenses. At the same time the solutions provide good preservative capacity and do not increase protein deposit.
Abstract:
This invention discloses an apparatus and method for hydrating or washing ophthalmic devices, comprising the step of directing to an ophthalmic device having a higher concentration of impurities fluid which has previously been directed to ophthalmic device having a lower concentration of impurities. Further, this invention provides a preferred device supporting member.
