Definitions
- the present invention relates to a water-soluble, solid contact lens care product according to the preamble of claim 1.
- Contact lenses are very popular with people with impaired vision. Proper care is still a problem when using contact lenses.
- a large number of different systems are known, which essentially have in common that the contact lens is disinfected after the contact lens has been worn, usually overnight, the disinfection being brought about by chemical agents which, because of their aggressive nature, have to be neutralized subsequently.
- chemical agents which, because of their aggressive nature, have to be neutralized subsequently.
- a large number of care products has established itself on the market.
- a combined contact lens care agent is described there, which both disinfects and cleans the contact lenses. Disinfection takes place here by means of a solution of hydrogen peroxide and a protease which is active in a solution containing peroxide. Subtilisin is mentioned as the corresponding protease.
- proteases are usually used in a separate cleaning step which is prior to disinfection. This requires an increased willingness of the user to carry out the cleaning and disinfection properly. After cleaning with proteases, this solution is usually discarded and then a separate disinfection phase is carried out. This two-stage process is perceived by users as annoying and promotes improper behavior through careless use. For example, the disinfection step may be forgotten and the lens removed directly from the protease solution. solution is put on. In another procedure, a protease is added to the disinfectant solution, but this is added in such a large amount that after the cleaning step the protease has to be removed again by means of a physiological solution. Otherwise, too much protease would remain in the contact lens matrix, which can cause irritation to the user's eye.
- the contact lens care agent according to the invention has at least a first and a second compartment.
- the first compartment contains at least one agent, in particular metabolic protease, for removing or supporting the cleaning of proteinaceous deposits on a contact lens.
- the at least second compartment contains at least one agent that is able to neutralize a contact lens disinfectant solution. It is essential to the invention that the first compartment dissolved more quickly in a contact lens disinfection solution than the second compartment. Both compartments can be exposed to the contact lens disinfectant solution at the same time.
- Proteases in particular proteases of the serine type, are suitable as agents for removing metabolic deposits. Particularly preferred is an enzyme class known as alkaline proteases, generally as subtilisin. Corresponding enzymes are characterized in EP 0 219 220.
- the second compartment contains a contact lens disinfectant, enzymes such as catalase or chemicals such as sodium dithionite being mentioned in the case of an aqueous hydrogen peroxide solution.
- the contact lens care agent according to the invention preferably consists of a first compartment and a second compartment.
- the first compartment completely encloses the second.
- the second compartment is preferably not enclosed on all sides by the second compartment. This gives the disinfectant solution simultaneous access to the compartments.
- the first compartment encloses the second compartment at least partially concentrically.
- it forms a molded body with two mutually perpendicular axes, the first compartment being arranged around a first axis and the second compartment being arranged around a second axis.
- the arrangement of the compartments is preferably rotationally symmetrical about an axis.
- the disinfectant comes into contact with the compartments and dissolves the first compartment faster than the second compartment.
- the dissolution of the first compartment can be accelerated by additives.
- Particularly suitable additives are substances which form a readily soluble matrix or mixtures of substances which produce bubbling in aqueous solution. It is particularly preferred to use additives which, after the compartments have dissolved, contribute to the formation of an isotonic solution.
- the second compartment can contain additives which delay the dissolution of the second compartment. This can be done, for example, by using less soluble substances or mixtures of substances than those used in the first compartment.
- FIG. 1 shows a preferred embodiment of the contact lens care agent according to the invention.
- an essentially cylindrical shaped body is the first compartment containing as a protease subtilisin.
- the essentially cylindrical shaped body, which contains the subtilisin compressed in a conventional tablet matrix, is enclosed by the second compartment, in the form of a torus, in the center of which is the essentially cylindrical shaped body of the first compartment.
- FIG. 2 shows a further embodiment in which the first compartment is drilled centrally and this hole is filled in the second compartment.
- FIG. 3 shows a further embodiment in which the first compartment completely encloses the second.
- the user first fills the aqueous disinfectant solution, preferably a 3% hydrogen peroxide solution, into cleaning devices known per se, adds the contact lens care agent according to the invention and the contact lenses to be cleaned and disinfected.
- the disinfectant solution dissolves the compartment containing subtilisin, so that the removal of the deposits on the lens begins.
- the contact lens is disinfected by the action of the disinfectant, H 2 0 2 .
- the second compartment is also dissolved more or less simultaneously with the disinfectant neutralizing agent. Due to the faster dissolution kinetics of the first compartment, it is already completely dissolved when the second compartment has only partially dissolved in the disinfectant solution.
- the catalase contained in the second compartment is then successively further dissolved in the disinfectant solution, so that there the catalase increasingly causes the decomposition of the hydrogen peroxide.
- a novel contact lens care system is made possible by the contact lens care agent according to the invention. This is because the user can determine an individual cleaning procedure which, after consultation with the contact lens adjuster, is tailored to the conditions of the user. For example, it is possible to carry out conventional disinfection, for example on two consecutive days, whereas the contact lens care agent according to the invention is then added on the third day, so that the protein does not have to be cleaned every day in the case of moderate contamination with proteins. In the case of heavier soiling, the protein deposition removal can also be carried out every other day, using the contact lens care agent according to the invention.
- the contact lens care agent according to the invention is presented, for example, in the form of blister packs in which tablets are then also offered which contain disinfectant neutralizers.
- a blister pack can be offered in which, starting with the contact lens care agent according to the invention in tablet form, two tablets are offered, for example, which does not contain the agent, in particular the protease, for removing metabolic deposits, for example protein deposits. Only on the fourth day will the contact lens care agent according to the invention appear in the blister pack, again followed by two tablets which only contain the neutralizing agent.
- the contact lens care agent according to the invention can also contain the substances in the compartments in granular form, the compartments e.g. b. are designed as capsules.
