Description

A care device and method for rigid gas permeable contact lenses and scleral lenses. Technical Field

[0001] This invention relates to the field of contact lens care and sterilization, and more particularly to a care device and method for rigid gas permeable contact lenses and scleral lenses. Background Technology

[0002] Currently, the care of contact lenses or scleral lenses generally involves manual rubbing with contact lens solutions. These solutions tend to have a pH that is either acidic or alkaline, with most being alkaline. These acidic or alkaline solutions can cause varying degrees of harm to the human body, fingers, and the contact lenses or scleral lenses themselves. Alternatively, some devices use automated cleaning and sterilization equipment to clean and sterilize contact lenses or scleral lenses. However, experiments have shown that if the original solution used is neutral, the cleaning and sterilization effect is generally limited. To achieve better results, alkaline solutions are typically used. However, alkaline solutions require specialized preparation, which adds a cost burden to users. Furthermore, the pH of alkaline solutions cannot be flexibly adjusted as needed, resulting in poor flexibility. Additionally, the storage and use of alkaline solutions present significant inconveniences. Therefore, finding a safe, harmless, inexpensive, and low-cost solution that also achieves excellent cleaning and sterilization effects has become a pressing problem for researchers in the industry.

[0003] Some contact lenses or scleral lenses are cleaned using a cleaning device, but the lenses generally need to be removed promptly after cleaning and rinsed before wearing. If they are left unremoved for a long time, they may cause the lenses to fade or have other adverse effects on the material. Therefore, how to thoroughly clean and sterilize contact lenses without affecting them after cleaning, and even allow them to be left unused, has become an increasingly important topic for researchers in the industry.

[0039] On one hand, the present invention provides a method for the care of rigid gas permeable contact lenses and scleral lenses, specifically including the following steps:

[0040] S1: Pour a chloride ion-containing solution into the inner and auxiliary compartments, and place the contact lens or scleral lens in the chloride ion-containing solution in the inner compartment;

[0041] S2: Connect the first electrode and the fourth electrode to the power supply. The first electrode is the anode, and the fourth electrode is the cathode. The first electrode undergoes an oxidation reaction, and the first electrode removes Cl- from the chloride-containing solution in the first auxiliary chamber. - Electrolysis produces Cl2, which dissolves in the solution to generate HCl and HClO. A reduction reaction occurs at the fourth electrode, which electrolyzes H2O in the chloride-containing solution inside the inner chamber to produce H2 and OH-. - This provides an alkaline environment for the inner warehouse;

[0042] S3: After the reaction in step S2, disconnect the power supply to the first and fourth electrodes, and connect the power supply to the third and fourth electrodes. Use electrophoresis and / or dissociation techniques to care for the contact lens or sclera.

[0043] S4: After cleaning and maintenance of the contact lens or scleral lens, disconnect the power supply to the third and fourth electrodes, and connect the power supply to the second and fifth electrodes. The fifth electrode is the anode, and the second electrode is the cathode. Under the action of the electric field, the ClO in the inner chamber... - OH - Cl - It passes through the anion exchange membrane and enters the second auxiliary chamber, where H+ ions are present. + Na + It enters the first auxiliary chamber through the cation exchange membrane.

[0044] Preferably, the auxiliary compartment includes at least a first auxiliary compartment and a second auxiliary compartment.

[0045] Specifically, the auxiliary chamber includes a first auxiliary chamber and a second auxiliary chamber; a cation exchange membrane is provided between the inner chamber and the first auxiliary chamber; at least one first electrode and at least one second electrode are provided in the first auxiliary chamber; at least one third electrode and at least one fourth electrode are provided in the inner chamber; an anion exchange membrane is provided between the inner chamber and the second auxiliary chamber; and at least one fifth electrode is provided in the second auxiliary chamber.

[0046] The auxiliary chamber may include a first auxiliary chamber, a second auxiliary chamber, and a third auxiliary chamber; a cation exchange membrane is provided between the first auxiliary chamber and the inner chamber, an anion exchange membrane is provided between the second auxiliary chamber and the inner chamber, and at least one first electrode is provided in the first auxiliary chamber; at least one third electrode and at least one fourth electrode are provided in the inner chamber, at least one fifth electrode is provided in the second auxiliary chamber, a cation exchange membrane is also provided between the third auxiliary chamber and the inner chamber, and at least one first electrode is provided in the third auxiliary chamber.

[0047] In a preferred embodiment of the nursing method described in this invention, in step S3, the third electrode is the anode and the fourth electrode is the cathode. An oxidation reaction occurs at the third electrode, and the third electrode reacts with the chloride ion solution in the inner chamber. - Electrolysis produces Cl2, which dissolves in the inner chamber and contains OH-. - ClO is produced in the solution - and Cl - A reduction reaction occurs at the fourth electrode, where the fourth electrode electrolyzes the H2O in the chloride-containing solution inside the inner chamber to produce H2 and OH-. - The ClO - It can sterilize and degrade proteins on contact lenses or scleral lenses.

[0048] As a preferred embodiment of the nursing method described in this invention, in step S3, after the third and fourth electrodes are powered on, an electrophoretic reaction also occurs. Under the action of the electric field, the tear proteins on the surface of the contact lens or sclera lens detach from the contact lens or sclera lens and move towards the electrode with the opposite charge.

[0049] As a preferred embodiment of the nursing method described in this invention, the chloride-containing solution is a NaCl solution; and / or

[0050] The first electrode, the third electrode, and the fifth electrode are all chlorine evolution electrodes.

[0051] As a preferred embodiment of the nursing method described in this invention, the NaCl solution is 0.9% physiological saline; and / or

[0052] In step S2, when the pH value of the solution in the inner chamber is in the range of 8-12.5, the power supply to the first and fourth electrodes is disconnected; and / or

[0053] In step S3, when cleaning and caring for contact lenses or scleral lenses, the stable voltage of the third and fourth electrodes after being powered on is 3.5-6.5V. The cleaning and sterilization of the contact lenses or scleral lenses is completed after the third and fourth electrodes react for 10-30 minutes; and / or

[0054] In step S4, the stable voltage of the second and fifth electrodes after being powered on is 10-30V. After the second and fifth electrodes react for 15-30 minutes, the solution in the inner chamber is converted into a neutral aqueous solution.

[0055] Compared with the prior art, the technical solution described in this patent has at least one or more of the following beneficial effects:

[0056] This patented ingenious structural and nursing method design ensures that after nursing care, the solution inside the inner compartment of the contact lens or scleral lens becomes a pure aqueous solution. This pure aqueous solution has no side effects on the contact lens or scleral lens, allowing them to be stored in the inner compartment for an extended period. The nursing device provided by this invention allows contact lenses or scleral lenses to remain in the inner compartment after cleaning and nursing care without needing to be transferred to other compartments or have the nursing solution drained and replaced with a long-term storage solution. After nursing care, the contact lenses or scleral lenses can continue to be stored in the nursing compartment without being removed, ensuring safety and harmlessness. No other operations are required; when needed, they are simply removed from the inner compartment for wearing, making it extremely convenient for customers.

[0057] The first and second auxiliary compartments are arranged one-to-one around the inner compartment, allowing for independent cleaning and care of different lenses and reaction processes. This design also enhances aesthetics, provides more intuitive operation, and minimizes the risk of misuse, resulting in a better and more comfortable user experience. The arrangement of the first and second auxiliary compartments around the inner compartment maximizes space utilization, resulting in a more rational design and effectively reducing the size of the care components.

[0058] This patent uses a neutral NaCl solution as the base solution for skincare products, which is inexpensive and readily available, reducing skincare costs for consumers. The neutral NaCl solution contains no added acidic or alkaline substances, is non-corrosive, has no chemical hazards, and is highly safe, significantly reducing production, storage, and transportation costs.

[0059] This patented technology automatically adjusts the pH value of a solution using a unique structure and method, offering high flexibility. By incorporating a first auxiliary chamber and a cation exchange membrane, an alkaline environment is provided for the solution within the inner chamber. This first auxiliary chamber effectively regulates the pH value within the inner chamber, ensuring that only a neutral NaCl solution is needed as the initial care solution. This makes the solution not only versatile and readily available, but also safe and harmless as it contains no acidic or alkaline substances, greatly facilitating user operation, production, storage, and transportation. Furthermore, the alkaline environment within the inner chamber inhibits the formation of HClO, ensuring that hypochlorite ions mostly exist as NaClO. NaClO has a relatively mild bactericidal and protein-removing effect, and the alkaline environment of sodium hypochlorite solution provides poor bleaching properties, preventing lens fading. The ClO in NaClO... - Ions can kill bacteria and degrade proteins, and with the help of electrophoresis, they can remove proteins.

[0060] Meanwhile, the first and second auxiliary compartments work together to ensure that after the contact lens or scleral lens care is completed, the solution containing the contact lens or scleral lens becomes a pure water solution, which facilitates the long-term storage of the contact lens or scleral lens.

[0061] This patented electrochemical cleaning and sterilization technology offers excellent sterilization and protein removal effects, effectively degrading proteins and providing immediate sterilization. The sterilization and protein removal process does not damage the contact lenses or scleral lenses themselves, exhibiting excellent stability and low toxicity. This device provides automatic cleaning, eliminating the need for manual scrubbing and avoiding contact with the cleaning solution, thus reducing harm to the user. The sterilization and protein removal time for contact lenses or scleral lenses is short, requiring only 20-60 minutes. Conventional cleaning solutions require at least 2-4 hours and necessitate manual scrubbing, which is time-consuming and labor-intensive.

[0062] At least the anode in both the inner and auxiliary chambers is a chlorine-evolving electrode. In the sodium chloride solution, the anode undergoes an oxidation reaction, releasing chlorine gas from chloride ions in the solution. The chlorine-evolving electrode exhibits strong corrosion resistance, high chlorine and acid resistance, good stability, good oxidation resistance, and a long service life. It prevents the anode itself from reacting or producing other products that could contaminate the electrolyte or cathode products. It also facilitates the removal of air bubbles between and on the electrode surface, effectively reducing the voltage in the electrolytic cell. Its shape is easy to manufacture, allowing for high precision. Generally, ruthenium-based, iridium-based, and platinum-based metal electrodes are used. Other inert electrodes (such as graphite and graphene materials) can also be used as chlorine-evolving electrodes provided the material's morphological stability is ensured. The electrodes can also be coated electrodes. The preferred electrode substrate is titanium or a titanium alloy substrate, coated with ruthenium-based, iridium-based, or platinum-based metal coatings. The cathode and anode are preferably symmetrically distributed on both sides of the inner chamber, close to the sidewalls for better protein removal.

[0063] Commercially available contact lens solutions can easily damage contact lenses or scleral lenses, and their sterilization rate is only around 90%. This patented solution achieves instant sterilization, not only with excellent sterilization effect but also with rapid sterilization speed. It achieves a 99% bacterial kill rate and a 99% fungal kill rate within 3 minutes, and kills Bacillus subtilis within 10 minutes, reaching sterilization level. Furthermore, commercially available contact lens solutions cannot be directly applied to the eyes. If users forget to rinse their contact lenses or scleral lenses after cleaning and wear them directly, the residual solution on the lenses can cause eye damage. Contact lenses or scleral lenses treated with this patented solution can be placed in a clean water solution and can be directly applied to the eyes. Even if the lenses are not rinsed after cleaning, they will not cause eye damage. Additionally, the AB solution contains potassium bromide, which produces liquid bromine during use. Liquid bromine can corrode the coating of contact lenses or scleral lenses, causing the coating to peel off. Coating peeling not only affects the lifespan of the contact lenses or scleral lenses, but also causes inflammation and other problems if the peeling coating falls into the eyes. Moreover, bromine residue on the contact lenses or scleral lenses can affect safety.

[0064] When the third and fourth electrodes inside the inner chamber of this patent are energized, the chloride ion-containing solution generates several types of oxidizing substances and free radicals, especially hypochlorous acid and hypochlorite ions, which can damage the peptide chains of proteins. The preferred mass concentration of hypochlorite ions in this patent is 0.1%, and the hypochlorite ion concentration of solution A in the AB solution is 0.375%. Although the AB solution can achieve good sterilization and protein removal effects, contact lenses or scleral lenses cannot be immersed in the AB solution for extended periods; otherwise, the AB solution will damage the contact lenses or scleral lenses, causing discoloration, corrosion, etc. This patent, due to the addition of electrophoresis technology, achieves excellent sterilization and protein removal effects with a preferred hypochlorite ion concentration of 0.1%, less than one-third of that in the AB solution. This makes it safer to use and easier to operate. Furthermore, by appropriately controlling relevant parameters, it can reduce discoloration of contact lenses or scleral lenses and prevent coating damage and corrosion.

[0065] The mass concentration of hypochlorite ions in this invention is controlled within the range of 0.01%-0.4%. Researchers, through extensive and long-term studies, discovered the optimal concentration range of hypochlorite ions and explored specific experimental conditions to maintain this concentration within the optimal range. These conditions include an optimal sodium chloride solution concentration of 0.9%, a power-on voltage of not less than 1.1V for the third and fourth electrodes, and a stable operating voltage range of 3.5-6.5V after power-on. The reaction time after power-on is 10-30 minutes.

[0066] The chloride ion-containing solution of this patent can generate hydroxyl radicals (OH·), oxygen radicals (O·), chloride radicals (Cl·), hydrogen peroxide (H2O2), ozone (O3), and hypochlorite ions (ClO2) under the action of an electric field. - Hypochlorous acid (HClO), chlorine gas (Cl2), hydrogen ions (H+) + The combination of substances such as [list of substances], along with electrophoresis under specific conditions, results in excellent protein removal and sterilization effects, comparable to AB solution. Furthermore, compared to AB solution, the concentration of hypochlorite ions produced in the reaction is less than one-third that of AB solution, making it safer and easier to use.

[0067] Compared to traditional hand-rubbing for cleaning contact lenses or scleral lenses, the cleaning and sterilization technology using this patented technology targets only charged particles on the lens, such as proteins, bacteria, and fungi. This more effectively separates denatured proteins from the lens without damaging it. This avoids problems such as insufficient rubbing force leading to incomplete removal of deposited proteins, excessive rubbing causing lens breakage, uneven rubbing causing lens deformation or scratches, and insufficient finger cleaning causing scratches or bacterial infections.

[0068] The contact lens or scleral lens cleaning and care technology of the present invention can kill bacteria and other microorganisms. Its sterilization principle mainly includes the following aspects:

[0069] 1. Electrolysis produces hypochlorous acid, which blocks the protein synthesis pathway in bacteria.

[0070] Electrolysis of a chloride-containing solution produces hypochlorous acid, a highly potent oxidizing agent. Hypochlorous acid works by oxidizing and denaturing the proteins in microorganisms, preventing them from replicating and thus rendering them unable to survive. Hypochlorous acid is 80 times more effective at killing microorganisms than hypochlorite ions and generates hydroxyl radicals that target various bacteria. Furthermore, with long-term use, bacteria do not develop resistance to electrolyzed saline solution, and it has no toxic side effects on the cornea.

[0071] 2. Electroincorporation: Electroincorporation refers to the process of introducing substances from solution into cells under the influence of an electric field. Based on the effects of an external electric field on bacterial growth, activity, metabolism, morphology, and motility, it involves the generation of hydroxyl radicals (OH·), oxygen radicals (O·), chlorine radicals (Cl·), hydrogen peroxide (H₂O₂), ozone (O₃), and hypochlorite ions (ClO₂) after the electrolysis of a chloride-containing solution. - Hypochlorous acid (HClO), chlorine gas (Cl2), hydrogen ions (H+) + A novel bactericidal and protein-removing technology has been developed. By applying an appropriate current, on the one hand, it can interfere with gene expression in cells, inhibit ATPase activity, reduce protein content within bacterial cells, affect free radical reactions and the synthesis of biological macromolecules, and inhibit cell proliferation by neutralizing the negative charge on the cell surface, ultimately leading to apoptosis, senescence, and death. On the other hand, it can enhance the permeability of microbial cells, causing electromixing, thereby inhibiting the generation of hydroxyl radicals (OH·), oxygen radicals (O·), chlorine radicals (Cl·), hydrogen peroxide (H2O2), ozone (O3), and hypochlorite (ClO2). - Hypochlorous acid (HClO), chlorine gas (Cl2), hydrogen ions (H+) + These substances penetrate into microbial cells, producing cytotoxicity and inducing cell structure and function disorders, thereby achieving the effects of inactivation, sterilization, and disinfection.

[0072] 3. Micro-electrolysis generates active substances that disrupt the chain structure of cellular organic matter.

[0073] Under the influence of a physical field, the current density is controlled by the energized state. Excited electrons are transferred from the anode to the cathode through the water medium. During this transfer, oxidizing substances such as O radicals and ClO are generated. - Cl - OH -H2O2 and other active substances can react with any molecules in living cells, such as sugars, phospholipids, and organic acids. The reaction is rapid, damaging the cell membrane and penetrating into the cell membrane to destroy the chain structure of organic matter. It also oxidizes the RNA and DNA of bacterial cells, causing them to become inactive or die. At the same time, bacteria are generally negatively charged in water and will migrate and aggregate towards the anode, which can cause bacterial discharge that directly kills them.

[0074] 4. Microcurrents pierce bacterial cell walls, rapidly oxidizing bacterial RNA / DNA.

[0075] The electric current acts directly on the cell wall, which can directly cause mechanical damage to bacteria in the solution and enhance the oxidation of bacterial and viral RNA and DNA.

[0076] 5. Microcurrents break up bacterial clusters and reduce bacterial tolerance.

[0077] The application of electric current alters the dispersion environment of bacteria in water, significantly reducing the stable state of bacterial aggregation. When bacteria and viruses are considered as colloidal systems composed of water, proteins, and nucleic acids, the microcurrent reduces bacterial stability, thereby decreasing their tolerance to hypochlorous acid.

[0078] 6. Electron-activated water enhances the contact surface between hypochlorous acid and bacteria.

[0079] The properties of water depend on changes in the electronic structure of water molecules, mainly changes in the distribution, shape, and direction of the electron cloud. Studies have confirmed that the electron cloud can be altered by the external environment. Under low voltage and microcurrent, four pairs of electrons in a water molecule jump from low orbits to high orbits, increasing the electron energy level and causing a loss of potential energy in activated water molecules, thus lowering their potential. This reduces the potential difference between water molecules and the interface (microbial surface). This change may affect the aggregation state of bacterial / viral particles. Furthermore, streptococci, Pseudomonas aeruginosa, Staphylococcus aureus, and other hydrophilic bacteria commonly found on contact lenses or scleral lenses are more easily contacted by hypochlorous acid after being exposed to microcurrent, thus improving the sterilization efficiency.

[0080] The rinsing chamber is equipped with a flexible mesh. When the contact lens or sclera is rinsed with ultrasonic vibration, the flexible mesh can physically clean the surface of the contact lens or sclera, making the surface of the contact lens or sclera cleaner and more thorough.

[0123] In the example, the support for the first exchange membrane assembly 16 is the first support 1614, and the support for the second exchange membrane assembly 17 is the second support 1615. The first support 1614 and the second support 1615 are integrally connected, and the first support 1614 and the second support 1615 are integrally connected by a circular ring 1616, which conforms to the shape of the inner chamber sidewall. In the example, ultrasonic lines are provided at the connection points of the first support 1614, the second support 1615, and the circular ring 1616 with the inner chamber main body sidewall. The first support 1614, the second support 1615, and the circular ring 1616 are all ultrasonically welded and sealed to the nursing chamber main body 15. Preferably, the first support 1614 and the second support 1615 are arranged in a mirror-symmetrical manner. Of course, the first support and the second support can also be different, and / or the two openings can also be different, and / or the two pressure plates can also be different, etc. This patent does not impose any restrictions on this, and can be flexibly adjusted as needed.

[0124] The first electrode 21, the second electrode 22, the third electrode 13, the fourth electrode 14, and the fifth electrode 31 are collectively referred to as electrodes. In this example, the electrodes are electrode probes. Of course, the electrodes can also be electrode sheets, etc., and this patent is not limited to this.

[0125] Preferably, a sinkhole 18 is provided at the bottom of the inner compartment. The third and fourth electrodes are not located in the sinkhole 18.

[0126] Preferably, the inner compartment includes a main area 191 and at least two extended areas 192, with the at least two extended areas 192 located outside the main area 191 and connected to it. The third and fourth electrodes are placed within the extended areas 192. In the example, the recessed groove 18 corresponds to the main area 191. In the example, the main area 191 is circular. In the example, there are two extended areas 192, symmetrically arranged outside the main area 191. In the example, the third electrode is placed within one extended area 192, and the fourth electrode is placed within the other extended area 192. More preferably, the first and second auxiliary compartments are both semi-circular, forming a ring around the outer side of the inner compartment, and the nursing compartment formed by the inner compartment, the first auxiliary compartment, and the second auxiliary compartment is circular. The third and fourth electrodes are placed in the extended areas, increasing the distance between the electrodes without increasing the volume of the nursing component.

[0127] The nursing component is also provided with a bottom cover 5.

[0128] Preferably, it also includes a conductive contact 51, which is electrically connected to the electrode and extends from the bottom cover 5. In the example, the conductive contact 51 extends from the bottom of the bottom cover 5.

In the example, the conductive contact 51 is in elastic contact with the spring tab 522. When the conductive contact 51 is pressed, the end of the conductive contact 51 near the electrode is accommodated in the installation opening 521. The spring tab facilitates the electrical connection between the conductive contact and the electrode, avoids loosening or poor contact, and also makes the conductive contact elastic, improving the stability and ease of use of the conductive contact.

[0130] In the example, the first electrodes of the two care compartments are connected in series. A cap and conductive contact are then installed on one of the first electrodes. This process is repeated for the second, third, fourth, and fifth electrodes. Identical electrodes within both care compartments are electrically connected, with one electrode also having a cap and conductive contact. Therefore, there are five conductive contacts. In the example, identical electrodes in the two care compartments are connected in series via wires. The conductive ends are wound as helical springs, which are then fitted onto the caps. Alternatively, identical electrodes in the two care compartments can be connected in series via a circuit board and then electrically connected to their corresponding conductive contacts, or the conductive contacts can also be electrically connected to the circuit board, with the corresponding electrodes in each care compartment connected to their corresponding conductive contacts via the circuit board. Using springs to connect the second electrode contacts facilitates assembly, ensures elastic contact that is not easily loosened, reduces the need for high assembly precision, and provides good stability.

In the example, the limiting member on the nursing component 10 is a limiting protrusion, and the limiting member on the nursing compartment is a limiting groove. Of course, this patent is not limited to this.

[0134] In the example, a PCB board is also provided inside the base, and the electrical contact points and control panel in the nursing tank are electrically connected to the PCB board.

[0135] In a preferred embodiment, as shown in Figures 1-2, a rinsing chamber 63 is also provided on the base. The rinsing chamber is configured to rinse contact lenses or scleral lenses, or to wet the lenses before wearing them. Specifically, sterile saline solution or multi-purpose eye care solution is poured into the rinsing chamber, the cap is removed, and the contact lens or scleral lens, which is held in the lens clip, is transferred into the rinsing chamber 63. The rinsing chamber 63 is then activated to rinse and wet the contact lens or scleral lens. Preferably, the rinsing chamber 63 is an ultrasonic vibration rinsing chamber. Of course, other rinsing methods are possible, and this patent does not limit this. More preferably, a flexible mesh (not shown in the figures) is also provided inside the rinsing chamber 63, and the lens clip containing the contact lens or scleral lens is placed within the flexible mesh. Preferably, the shape of the flexible mesh matches the shape of the lens clip containing the contact lens or scleral lens. A flexible mesh is placed inside the rinsing chamber. A lens holder containing contact lenses or scleral lenses is then placed inside the rinsing chamber. The rinsing mode is activated to rinse the contact lenses or scleral lenses. After rinsing, the contact lenses or scleral lenses can be worn. Preferably, an ultrasonic component is located at the bottom of the rinsing chamber 63. Preferably, the flexible mesh is detachable and placed inside the rinsing chamber. This facilitates regular or irregular thorough cleaning or sterilization of the flexible mesh. With the flexible mesh in place, during ultrasonic vibration rinsing of the contact lenses or scleral lenses, the flexible mesh can physically clean the surface of the contact lenses or scleral lenses, resulting in a cleaner and more thorough cleaning.

[0136] Preferably, as shown in Figures 1-2, the base is also provided with an accessory receiving slot 64, which is configured to accommodate tweezers and / or suction sticks, etc.

[0137] Preferably, the base is also provided with a top cover (not shown in the figure), which covers at least the nursing compartment. In the example, the top cover covers the nursing compartment, the rinsing compartment, and the accessory receiving slot.

[0138] On the other hand, the present invention provides a method for caring for rigid gas permeable contact lenses and scleral lenses, specifically including the following steps:

[0139] S1: Pour a chloride ion-containing solution into the inner and auxiliary compartments, and place the contact lens or scleral lens in the chloride ion-containing solution in the inner compartment;

[0140] S2: Connect the first electrode and the fourth electrode to the power supply. The first electrode is the anode, and the fourth electrode is the cathode. The first electrode undergoes an oxidation reaction, and the first electrode removes Cl- from the chloride-containing solution in the first auxiliary chamber. - Electrolysis produces Cl2, which dissolves in the solution to generate HCl and HClO. A reduction reaction occurs at the fourth electrode, which electrolyzes H2O in the chloride-containing solution inside the inner chamber to produce H2 and OH-. - This provides an alkaline environment for the inner warehouse;

[0141] S3: After the reaction in step S2, disconnect the power supply to the first and fourth electrodes, connect the power supply to the third and fourth electrodes, and clean and care for the contact lens or scleral lens using electrophoresis and / or dissociation techniques.

[0142] S4: After cleaning and maintenance of the contact lens or scleral lens, disconnect the power supply to the third and fourth electrodes, and connect the power supply to the second and fifth electrodes. The fifth electrode is the anode, and the second electrode is the cathode. Under the action of the electric field, the ClO in the inner chamber... - OH - Cl - It enters the second auxiliary chamber through the anion exchange membrane, and the H+ in the inner chamber... + Na + It enters the first auxiliary chamber through the cation exchange membrane.

[0143] Preferably, the auxiliary compartment includes at least a first auxiliary compartment and a second auxiliary compartment.

[0144] Specifically, the auxiliary chamber includes a first auxiliary chamber and a second auxiliary chamber; a cation exchange membrane is provided between the inner chamber and the first auxiliary chamber; at least one first electrode and at least one second electrode are provided in the first auxiliary chamber; at least one third electrode and at least one fourth electrode are provided in the inner chamber; an anion exchange membrane is provided between the inner chamber and the second auxiliary chamber; and at least one fifth electrode is provided in the second auxiliary chamber.

[0145] The auxiliary chamber may include a first auxiliary chamber, a second auxiliary chamber, and a third auxiliary chamber; a cation exchange membrane is provided between the first auxiliary chamber and the inner chamber, an anion exchange membrane is provided between the second auxiliary chamber and the inner chamber, and at least one first electrode is provided in the first auxiliary chamber; at least one third electrode and at least one fourth electrode are provided in the inner chamber, at least one fifth electrode is provided in the second auxiliary chamber, a cation exchange membrane is also provided between the third auxiliary chamber and the inner chamber, and at least one first electrode is provided in the third auxiliary chamber.

[0146] In a preferred embodiment, in step S3, the third electrode is the anode and the fourth electrode is the cathode. The third electrode undergoes an oxidation reaction, and the third electrode removes Cl- from the chloride ion solution within the inner chamber. - Electrolysis produces Cl2, which dissolves in the inner chamber and contains OH-.- ClO is produced in the solution - and Cl - A reduction reaction occurs at the fourth electrode, where the fourth electrode electrolyzes the H2O in the chloride-containing solution inside the inner chamber to produce H2 and OH-. - The ClO - It is capable of sterilizing contact lenses or scleral lenses and degrading proteins on them. In the example, the ClO... - It can sterilize contact lenses or scleral lenses and degrade proteins on them. Since step S2 has provided an alkaline environment for the inner chamber, the NaClO inside the inner chamber is less likely to hydrolyze to produce HClO, thereby reducing the adverse effects of HClO on lens fading and material properties.

[0147] In a further preferred embodiment, in step S3, after the third and fourth electrodes are powered on, an electrophoretic reaction also occurs. Under the influence of the electric field, tear proteins on the surface of the contact lens or sclera detach from the contact lens or sclera and move towards the electrode with the opposite charge. In this example, the degraded proteins move towards the electrode with the opposite charge under the influence of the electric field, thus achieving sterilization and protein removal of the contact lens or sclera.

[0148] In a preferred embodiment, the chloride-containing solution is a NaCl solution. More preferably, the NaCl solution is a 0.9% (w / w) physiological saline solution.

[0149] Preferably, in step S2, the pH value of the solution in the inner chamber is in the range of 8-12.5, and the power supply to the first electrode and the fourth electrode is disconnected.

[0150] Preferably, in step S3, when cleaning and caring for contact lenses or scleral lenses, the ClO content in the inner chamber solution is controlled. - The mass concentration is 0.01%-0.4%. The cleaning and sterilization of the contact lens or scleral lens is completed after the third and fourth electrodes react for 10-30 minutes.

[0151] In the example, in step S4, an oxidation reaction occurs at the fifth electrode, where the fifth electrode reacts with Cl- in the chloride ion solution within the inner chamber. - The reaction is Cl2, and a reduction reaction occurs at the second electrode. The second electrode removes H+ from the chloride ion solution in the inner chamber. + The reaction produces H2. The fifth electrode is the anode; under the influence of the electric field, ClO in the inner chamber... - OH - Cl - It passes through the anion exchange membrane and enters the second auxiliary chamber; the second electrode is the cathode, and under the action of an electric field, the H+ in the inner chamber... + Na + It enters the first auxiliary chamber through the cation exchange membrane. The ClO in the inner chamber... -OH - Cl - H + Na + The solution passes through anion exchange membranes and cation exchange membranes respectively, entering the second auxiliary chamber and the first auxiliary chamber. As the reaction proceeds, the inner chamber gradually becomes a pure aqueous solution. Once the inner chamber is filled with pure aqueous solution, the reaction in step S4 stops, and the contact lens or scleral lens is placed in the pure aqueous solution within the inner chamber. The pure aqueous solution has no side effects on the contact lens or scleral lens, allowing it to be stored in the inner chamber for an extended period. The care device provided by this invention allows contact lenses or scleral lenses to be stored in the inner chamber after cleaning and care without needing to be transferred to other chambers or have the care solution poured out and replaced with a long-term storage solution. After care is completed in the care chamber, the contact lens or scleral lens can continue to be stored there without being removed, ensuring safety and harmlessness. No other operations are required; when needed, it can simply be removed from the inner chamber for wearing, which is very convenient for customers.

More preferably, in step S2, the stable voltage after connecting the power to the first and fourth electrodes is 5V, the power is disconnected after 1 minute of operation, and the pH value in the inner chamber is adjusted to the range of 10-12.5. Of course, this patent is not limited to these embodiments; the working time and working voltage in step S2 can be selected with other values ​​as needed.

[0153] Preferably, in step S3, the power-on voltage for connecting the third and fourth electrodes is not less than 1.1V, the stable voltage after connecting the third and fourth electrodes is 3.5-6.5V, the effective chlorine concentration of the solution in the inner chamber is controlled within the range of 0.01%-0.6%, and the cleaning and sterilization of the contact lens or scleral lens is completed after the third and fourth electrodes react for 10-30 minutes. It should be noted that effective chlorine refers to the amount of chlorine equivalent to the oxidizing power of the chlorine-containing disinfectant, and its content is expressed as a percentage concentration (%). More preferably, the ClO₂ content in the solution is controlled... - The mass concentration is 0.01%-0.4%. More preferably, in step S3, the stable voltage of the third and fourth electrodes after being powered on is 5V, and the power is disconnected after approximately 20 minutes of operation to achieve optimal sterilization and protein removal effects, and the safest operating environment. More preferably, the ClO in the solution is controlled... - The mass concentration is 0.01-0.229%.

More preferably, in step S4, the second and fifth electrodes operate at 30V, and the power is disconnected after approximately 15 minutes, after which the alkaline sodium hypochlorite solution in the inner chamber is converted into a neutral aqueous solution. Of course, this patent is not limited to these values; the working time and voltage in step S4 can be selected according to needs. As shown in Table 1 and Figure 16 below, the effective chlorine concentration in the solution in the inner chamber changes with the stable voltage and time in step S4.

[0155] Table 1 shows the changes in the effective chlorine concentration in the inner chamber solution during step S4, as the stable voltage and time change.

[0156] In step S2, after the first electrode and the fourth electrode are connected to the power supply, the first electrode becomes the anode and the fourth electrode becomes the cathode. The following reaction occurs at the cathode and the anode:

[0157] Anode: 2Cl - -2e - →Cl2↑ (Ⅰ)

[0158] Cl₂ + H₂O = HCl + HClO (II)

[0159] Cathode: 2H₂O + 2e⁻ - =H2↑ + 2OH - (III)

[0160] In step S2, on the one hand, this reaction creates an alkaline environment for the inner chamber; on the other hand, the cation exchange membrane can block anions from passing through the cation exchange membrane, especially blocking ClO in the first auxiliary chamber. - It passes through the cation exchange membrane into the inner chamber. The advantage of this step is that contact lenses or scleral lenses are less likely to fade during this and subsequent steps.

[0161] In step S3, after the third and fourth electrodes are powered on, the following reactions occur at the cathode and anode:

[0162] Anode: 2Cl - -2e - →Cl2↑ (Ⅳ)

[0163] Cathode: 2H₂O + 2e⁻ - =H2↑ + 2OH- (V)

[0164] The overall electrolysis reaction inside the inner chamber is: 2NaCl + 2H₂O = Cl₂ + H₂ + 2NaOH. The Cl₂ produced by electrolysis reacts with NaOH to form NaClO. Therefore, the solution in the inner chamber mainly contains NaOH, NaClO, and H₂O. Step S3 can sterilize contact lenses or scleral lenses. NaClO can decompose proteins, and electrophoresis can peel off proteins. The combination of electrophoresis and electrolysis makes protein removal more complete. Furthermore, ClO… - It has a bactericidal effect; the ClO inside the chamber... - A small amount of HClO has a bactericidal and protein-removing effect, while ClO - A small amount of HClO is unlikely to cause fading of contact lenses or scleral lenses.

[0165] ClO in the inner chamber solution of step S3 - The following dynamic equilibrium exists:

[0166] OH in the inner chamber solution - At higher concentrations, this dynamic equilibrium shifts to the left, decreasing ClO₂ levels. - Hydrolysis reduces the amount of HClO in the solution.

[0167] Step S2 creates an alkaline environment in the inner chamber, that is, the reaction produces OH-. - This is to prevent excessively high local HClO concentration in the inner chamber during step S3, which could cause localized fading of the contact lenses or scleral lenses. If an alkaline environment is not created in the care chamber, especially if the HClO concentration is too high near the third electrode, localized fading or uneven coloring of the contact lenses or scleral lenses will occur, severely affecting their use. As shown in Figure 17, the attached figure is a comparison between contact lenses or scleral lenses cleaned and cared for using the technical solution of this invention without fading, and contact lenses or scleral lenses cleaned and cared for using conventional methods that do not provide an alkaline environment and fading.

[0168] Furthermore, in routine care methods that do not include step S4, if contact lenses or scleral lenses are still placed in the storage compartment after the care in step S3, the lenses will still fade if left there for an extended period. This is because the pH value of the solution in the storage compartment decreases over time. This is because carbon dioxide in the air dissolves in the storage compartment solution and reacts with NaOH to form sodium carbonate. The pH of the alkaline environment decreases, shifting the hydrolysis equilibrium in equation (VI) to the right, increasing the amount of HClO. HClO has a certain bleaching property, and an increase in HClO easily causes the lenses to fade. In addition, NaClO also has a certain bleaching property, further increasing the amount of HClO.

[0169] In step S4, besides the oxidation reaction occurring at the fifth electrode and the reduction reaction occurring at the second electrode, the ions in the inner chamber at this time include ClO. - OH - Cl - H + Na + After energizing in step S4, under the influence of the electric field, the ClO in the inner chamber... - OH - Cl - It passes through the anion exchange membrane and enters the second auxiliary chamber, where H+ in the inner chamber... + Na + It passes through the cation exchange membrane into the first auxiliary chamber until the solution in the inner chamber becomes a pure aqueous solution. The contact lens or scleral lens can then be stored for a long time in a pure aqueous solution environment.

[0170] At least the first, third, and fifth electrodes are chlorine-evolving electrodes. In a chloride-ion-containing solution, an oxidation reaction occurs at the anode, releasing chlorine gas from the chloride ions in the solution. Chlorine-evolving electrodes possess strong corrosion resistance, high chlorine and acid resistance, good stability, good oxidation resistance, and a long service life. They can prevent the anode itself from reacting or producing other products that could contaminate the solution or cathode products. Chlorine-evolving electrodes also facilitate the removal of air bubbles between electrodes and on the electrode surface, effectively reducing the voltage in the treatment chamber. Their shape is easy to manufacture and allows for high precision. Generally, ruthenium-based, iridium-based, and platinum-based metal electrodes are preferred. Other inert electrodes (such as graphite and graphene materials) can also be used as chlorine-evolving electrodes provided that the material's morphological stability is ensured. The electrode substrate is preferably a titanium alloy substrate or a platinum-plated substrate. In this example, the first, second, third, fourth, and fifth electrodes are all chlorine-evolving electrodes.

[0171] In other embodiments, when contact lenses or scleral lenses require rinsing, sterile saline solution or a multi-purpose eye-safe solution is used to rinse them, or sterile saline solution or a multi-purpose eye-safe solution is poured into the rinsing chamber, and the rinsing mode is activated to rinse the contact lenses or scleral lenses. Of course, after rinsing, it is preferable to apply lubricating fluid to the concave surface of the contact lens or scleral lens before wearing and using it.
