摘要:
A method of disinfecting a hydrogen peroxide stable material by contacting said material with a hydrogen peroxide containing solution and a hydrogen peroxide decomposition means adapted to permit said material to have a cumulative (% peroxide).multidot.(min) exposure from the time said decomposition means contacts said hydrogen peroxide containing solution over a period not exceeding 12 hours of at least 20% (peroxide).multidot.(min). Also, disclosed are devices and components thereof whereby said method can be achieved.
摘要:
A method of disinfecting a hydrogen peroxide stable contact lens is provided wherein a contact lens is contacted with a hydrogen peroxide solution in a container and a hydrogen peroxide decomposition means is provided in said container, which means is adapted to permit the contact lens to have a cumulative (% peroxide) (min) exposure from the time said decomposition means contacts said peroxide containing solution, time zero, over a period of no greater than 12 hours of at least 20% peroxide.multidot.minute. An apparatus capable of carrying out such method is also provided herein. The hydrogen peroxide decomposition means may be, for example, a prepoisoned catalyst, a catalyst partially enclosed in a tube, a dual catalyst control system or a distributed catalyst control system.
摘要:
A method of carrying out a reaction in a solution catalytically comprising contacting a solid catalytically active material and a solution in which a catalytic reaction is to be carried out wherein the catalytic reaction yields a gas which adheres to the catalyst particles such that as the reaction is substantially complete in the immediate environment of the catalyst, the catalyst migrates to a reactant richer portion.
摘要:
An ophthalmic solution comprising a hydrogen peroxide source in an amount sufficient to result in between about 0.001% and about 0.01% by weight stabilized hydrogen peroxide in said formulation as a preservative, one or more ocularly-compatible hydrogen peroxide stabilizers, hydroxypropylmethylcellulose and sodium carboxymethylcellulose, as well as pharmaceutical compositions comprising such solutions, are provided.
摘要:
Compositions and methods for reducing the decomposition rate of polymeric bioadhesives and viscosity enhancers, such as poly(acrylic acids). The compositions include at least one strong, stable chelating agent, preferably an organophosphorous compound such as diethylene triamine penta(methylene phosphonic acid). These biocompatible compositions are especially useful in the ophthalmic field.

摘要:
A rapid cleaning and disinfecting method and composition for ophthalmic devices, e.g. contact lenses. The composition includes, on a weight basis, 10-50% of a C.sub.3-8 alkylene glycol, 2-30% of a lower alkanol, 2-15% of a surfactant, 0-2% pH adjusting agent, 0-5% tonicity builder, viscosity enhancing agent in an amount from 0 to the amount required to bring the solution viscosity to 100 cps, and the balance water. The method involves mechanically rubbing the ophthalmic device with the cleaning/disinfecting composition followed by rinsing the device.
摘要:
A disinfection solution, primarily for use in conjunction with contact lenses is disclosed comprising an amount of a pharmaceutically acceptable ionic salt which is equivalent in ionic strength to at least 5% w/v sodium chloride, at least one of a C.sub.2-6 alkanol and a C.sub.3-8 alkylene glycol, a pharmaceutically acceptable surfactant, optionally a buffer, and water.
摘要:
Ophthalmic compositions comprising ketotifen and a source of hydrogen peroxide providing an amount of hydrogen peroxide of from about 0.001 to about 0.1% (w/v) of hydrogen peroxide, and methods for the treatment and prevention of allergic conjunctivitis using these compositions are provided herein.
摘要:
The present invention provides a lens care composition having a persistent cleaning-efficacy characterized by substantially maintaining the light transmittance at around 280 nm of a contact lens after at least 15 cycles of soiling with a soiling solution containing proteins and subsequent cleaning with the lens care composition of the invention. The lens care composition comprises at least one surfactant, a polyvinylpyrrolidone (PVP), a cellulose ether, and xylitol, wherein in combination with polyvinylpyrrolidone (PVP), a cellulose ether, and xylitol, the surfactant provides the persistent cleaning-efficacy.
