摘要： A contact lens cleaner and a method for protein removal and sterilization by electrophoresis dissociation are disclosed. The contact lens cleaner comprises a lens cleaning tank (10), two electrophoresis dissociation probes (20) are arranged in the lens cleaning tank (10) opposite each other, and the electrophoresis dissociation probes (20) are electrically connected to a circuit power supply. The lens cleaning tank (10) is filled with an electrolyte solution; a lens to be cleaned is placed in the lens cleaning tank (10); and a switch is turned on, and the two electrophoresis dissociation probes (20) in the lens cleaning tank (10) form an anode and a cathode. There are lacrimal proteins on the surface of the lens to be cleaned, the lacrimal proteins are charged in the solution, and the charged lacrimal proteins move to the electrode opposite to the electrical property thereof in the cleaning tank (10) according to the phenomenon of electrophoresis. The electrolyte solution reacts chemically in the cleaning tank (10) to produce hypochlorite having a strong oxidizing property, and the hypochlorite can degrade the lacrimal proteins, and also can sterilize and disinfect.

摘要： A method of protein deposition for detecting a protein removal effect, a protein culture solution, and a protein cleaning and testing instrument, including preparing a protein culture solution: mixing a protein and a deionized water to obtain a diluted protein solution and adjusting a PH value of the diluted protein solution, to obtain the protein culture solution; and culturing the corneal contact lens using the protein culture solution: placing the corneal contact lens and the protein culture solution in a culture container for sealed culture within a culture temperature range for a time duration, to obtain a protein deposited corneal contact lens. The method is more suitable to be used as a testing sample of a protein removal effect testing experiment, reducing the difficulty in testing and judging of the degree of fouling of the corneal contact lens and the cleaning effect of the protein removal effect testing experiment.

摘要： A method for effectively measuring the tear protein content of a soft hydrophilic corneal contact lens is provided in the present invention. The method comprises: preparing a protein extraction solution by mixing acetonitrile, pure water and trifluoroacetic acid; placing the soft hydrophilic corneal contact lens with protein adsorbed on its surface into the protein extraction solution so that the protein extraction solution separates the protein from the soft hydrophilic corneal contact lens; taking out the soft hydrophilic corneal contact lens from the protein extraction solution; detecting a protein concentration in the protein extraction solution by a micro ultraviolet spectrophotometer to obtain a concentration value of the adsorbed protein on the soft hydrophilic corneal contact lens; and calculating a content value of the adsorbed protein on the soft hydrophilic corneal contact lens based on the concentration value of the adsorbed protein on the soft hydrophilic corneal contact lens and a volume of the protein extraction solution. By means of the method, the tear protein content on the surface of the soft hydrophilic corneal contact lens may be quantitatively and qualitatively detected, thus providing users with experimental test data and ensuring the safety of user consumption and use.
