The present invention relates to a lens care solution having 0.001 to about 5 weight percent of a low molecular weight amine of the general formula: ##STR00001## where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are H or low molecular weight radicals, and R.sub.5 is a low molecular weight radical, or salt thereof; an effective amount of a tonicity agent; and the balance water.

A storage solution for an ophthalmic lens comprises an osmotic pressure adjusting agent, sodium chloride, and deionized water. The osmotic pressure adjusting agent is selected from a group consisting of betaine, L-carnitine, and erythritol, or any combination thereof. The storage solution has an osmotic pressure of about 280 mOsm/kg to about 320 mOsm/kg. The disclosure also provides an ophthalmic product using the storage solution.

Provided is an ocular device case with a new structure that can solve unexpected problems in the related art, for example, adverse effects on user's eyes by splashes of treatment liquid upon pouring the treatment liquid into the device case from a separate refill container. In a device case 10 including: a case body 18 accommodating treatment liquid 12 with ocular devices such as a contact lens 16; and a lid 20, a container receiving portion 48 is provided such that a spout 106 of a refill container 100 is brought into contact with the refill receiving portion 48 so as to allow the treatment liquid 12 to flow into the device case 10.

Sterile container (1) comprising a container body (40) having inner surfaces (2, 4) delimiting a containment compartment (6), wherein at least part of said surfaces (2, 4) is made of a compound material comprising a thermoplastic polymer, a first zeolite and a second zeolite homogeneously dispersed in the thermoplastic polymer, each of said zeolites having a micrometric particle size distribution and delimiting reticular voids in which bactericidal and/or bacteriostatic metal ions releasable from said zeolite are housed. The first zeolite comprises silver and copper metal ions, the second zeolite comprises silver and zinc metal ions. The present invention further relates to a sterile product and a compound material.

A disinfection system of a contact lens comprising immersing the contact lens in a disinfecting solution containing hydrogen peroxide in a concentration of 1 to 10% and neutralizing the hydrogen peroxide in the disinfecting solution through contact with a metal catalyst, where the disinfecting solution contains an organic carboxylic acid or a salt of the organic carboxylic acid, the organic carboxylic acid having a structure in which a hydroxyl group and a carboxyl group are bonded to one carbon atom; the disinfecting solution is adjusted to have a pH of 6 to 8; and the disinfecting solution after the neutralization is adjusted to have an osmotic pressure of 250 to 350 mOsm.

A system for releasing a contained volume of gas. The system has a base with a pressure-release vent positioned within a flex region and a seal to disengagably seal the pressure-release vent. The seal has a gas vent path that extends from the pressure-release vent. The contained volume of gas passes through the gas vent path to apply force against the flex region and disengage the seal from the pressure-release vent, allowing the gas to exit through the pressure-release vent.

A method of operating a sterilization system having a vacuum chamber for sterilizing instruments, the chamber connected to a reservoir of sterilant by a valve in a closed state, is disclosed. The method may include taking a baseline humidity measurement while the pressure within the chamber is a first pressure, lowering the pressure within the chamber to a conditioning pressure, maintaining the conditioning pressure for a dwell time, increasing the pressure within the chamber, acquiring a second humidity measurement from within the chamber, and comparing the baseline humidity measurement to the second humidity measurement.

A lens aid, lens aid system and powered light source that uses a lens cup of soft pliable material providing an improved visual method including a hands-free or one hand method for the insertion of a contact lens and more preferably a scleral lens into the eye.

A contact lens storage case of limited life and predetermined usage to further the safe and effective use of contact lenses by ensuring patient compliance through both limiting case use over a set period of time and discouraging reuse and topping-off of the disinfecting and storage solution. Generally, the self-destruction consists of the case developing a leak in a pre-determined fashion as a result of the change in properties of a material in a limited area of the case following exposure of the case to the storage solution.

A system for releasing a contained volume of gas. The system has a base with a pressure-release vent positioned within a flex region and a seal to disengagably seal the pressure-release vent. The seal has a gas vent path that extends from the pressure-release vent.
