This method can make the Yuanyanxu disinfection during storage and then neutralize it, so that it can be used directly in the eyes without washing. [Prior art] Regarding the preservation and disinfection of contact lenses, it is generally known that sterilization by means of an oxidizing system such as hydrogen peroxide is indeed the most effective and safest. For example, if the toilet uses a disinfectant containing ethylmercury thiosalicylic acid, dichlorobenzene and dipulse hexane, etc., 10 the time spent (usually 6 to 8 hours) on the disinfection solution is compared with Faster disinfection time (requires 15% for 3% hydrogen peroxide solution), its safety is enhanced.一旦 Once the contact lenses have been sterilized with a hydrogen peroxide solution, they must be immersed in a neutral saline solution that can decompose (or neutralize) the peroxide remaining in them. 15 Most manufacturers use catalase in these neutralization solutions to get the contact lens on the eye within 15 minutes. These traditional systems containing hydrogen peroxide disinfectants and neutralizer solutions are generally called two-step systems. For users, they must continue to replace the disinfectant with a neutralizer. 2 Recently, Allergan uses tablets with the same function to replace the neutralization solution, that is, once the contact lens is sterilized with a peroxide solution, all hydrogen peroxide can be inactivated, and the solution is converted into a clear eye phase. The tablets of the contained medium are incorporated in the same solution. This new system can also be called a two-step system due to user intervention. 25Next Continued 5 1222369 Description of Invention Continued
Ciba Geigy公司已向市 氣消毒液倒入帶有能始過氧 中。該體系與前一種體系不 包含一步驟。 場推出一種體系,即將過氧化 化物失活的塗有鉑黑環之容器 同’以使用者毋庸介入,而僅 然而,鉑環一開始就馬上分解過氧化物,沒有足夠時 間以保證消毒,因此而受到嚴厲貴難。所謂單步驟體系可 見於例如EP-A-0209071 (歐洲專利申請861〇9361 $ )中,Ciba Geigy has poured commercial disinfectant into the air with a starting oxygen. This system does not include a step from the previous system. In the field, a system was introduced, in which a container coated with a black platinum ring was deactivated with the same peroxide as the user. However, the platinum ring immediately decomposed the peroxide without sufficient time to ensure disinfection. And severely expensive. The so-called single-step system can be found in, for example, EP-A-0209071 (European patent application 860099361 $),
而在其他發明中也曾提到與本案相似的體系,惟尚無申請 1〇專利提到隱形眼鏡實際上可於保存處理後直接裝置於眼晴 上。事實上,對於酸性介質提到的塗層是二甲基氨基甲基 丙缔酸酯聚合物與中性甲基丙烯酸酯,由於彼等非常刺激 眼晴,而必須徹底清洗眼鏡。至於中性介質,可參考塗覆 劑,因其刺激性或不溶性,而使得眼鏡在使用前必須再加 15清洗。於此兩種情況下,隨後清洗眼鏡乃是各該單步驟體 系之缺點。 【發明內容】In other inventions, a system similar to the present case has been mentioned, but there is no application yet. 10 The patent mentions that the contact lens can actually be directly installed on the eye after storage and treatment. In fact, the coatings mentioned for acidic media are dimethylaminomethyl acrylate polymers and neutral methacrylates, as they are very irritating to the eyes and must be washed thoroughly. As for the neutral medium, please refer to the coating agent. Because of its irritation or insolubility, the glasses must be washed for 15 more times before use. In both cases, subsequent cleaning of the spectacles is a disadvantage of the one-step system. [Summary of the Invention]

Moreover, two months of testing and clinical observation on 20 people show that the system described in the present invention is completely compatible with human eyes. The system of the present invention involves a single step because the user can handle the eyes without intervention. The characteristics of the tablet make the disinfection and neutralization of peroxides not at the same time, but the neutralization after disinfection, which is a clear advantage over the platinum ring system. 25 [V] Continued Page 1222369 Description of the Invention I Selling Page This invention relates to a method for disinfecting, aging and neutralizing contact lenses. ^ Body, language: It is included in a container for storing contact lenses, and simultaneously receives hydrogen peroxide / hypertensive (disinfectant) and a tablet containing active peroxidase (Shu media) 5 J 〃 in two hours 疋Two things: it can sterilize and moisturize the invisible eyes, and transform the medium into a saline solution that is completely compatible with the eyes. / Essence is a special coating made on the surface of the neutralizing tablet. Once the lenses are disinfected, U will start neutralizing and smoothing to lubricate the contact lenses and convert the 10 solution into a pH of 7 · 2: 4 etc. Osmotic saline does not need to be washed and is directly installed on the eye nitrile. Hydrogen peroxide disinfectant solutions also contain stabilizers (such as acetoaminophenyl ether) and buffers (such as monosodium phosphate) to prevent decomposition of lice compounds. The tablet also contains a peroxide neutralizer component, sodium chloride (a ratio of 15 can convert 10 ml of disinfection solution into an isotonic solution) and monosodium phosphate (the content of which is sufficient to convert ρΗ3.0 〇mi peroxide disinfectant solution was converted to a pH of 7 2 · 7.4). The tablet coating comprises a polymer, polyvinylpyrrolidone, which is soluble in the dosage, and is added in an amount sufficient to delay the peroxide neutralization reaction for about 15 minutes. Coating 20 can be applied by simple methods, such as spraying polymer on a trough with suction device; or by more controlled methods such as fluidized bed, Accela cota, Pellegrini, etc. to obtain the coating . Polymer spraying requires solvents such as sterile water, ethanol, isopropanol, dichloromethane, and acetone. In an embodiment of the invention, the coating of the tablet further comprises a colorant. 25 0 Continued on page 7 1222369 The coloring agent used is vitamin β2, which is a photosensitive compound that is characterized by making the solution bright yellow and colorless by photodegradation. 5 The use of coloring agents in the tablets of the present invention is to let the user know when it is possible to use contact lenses. Specifically, the coloring agent contained in the Xibu coating can make its color change detection easier and faster. In addition, since the colorant is not intimately mixed with the core component, the colorant will not be degraded by the component 'to avoid interference with color detection. [Embodiment] The implementation of the entire method of the present invention can be described as follows: The container for storing contact lenses is filled with a 10ml disinfectant solution and the tablets are neutralized. The solution sterilizes the lenses in the first 10 minutes, and the tablet coating slowly dissolves. After 10 or 15 minutes, a small amount of neutralization reaction was started and the homing was reached after 15-17 minutes. After 10_25 minutes, you can: all neutralize the reaction. After 60 minutes, the tablet is completely dissolved and the invisible: mirror is now ready for use. The application range of the tablet composition peroxide disinfectant solution and neutralizer tablet is as follows: Disinfectant solution 2.8-3.5% w / v hydrogen peroxide (Uo. 3% w / v scale acid single steel χ 2Η200- 008-0.015O / OW / V Acetylaminophenylacetic acid was adjusted to a pH of 2.8-3 with 37% hydrochloric acid. 25 0 Continuation sheet 15 Cheng Lu 20 8 Description of the invention Continuation sheet neutralizer tablets (for 10ml disinfection Agent solution) 5 0-7 〇mg 560-IO〇mg 2080-5400UI 60-11 Omg 025-0.25mg disodium sodium phosphate x 2H20 lyophilized catalase polyvinylpyrrol Alkanone (coating polymer) Vitamin B2 The following are some examples of implementing the present invention: 10 Example 1 Disinfectant solution 3.2% w / v 0.20% w / v 〇.13% w / v hydrogen peroxide Monosodium phosphate χ 2Η20 Ethylaminophenyl ether 15 Adjusted to 37 with 37% hydrochloric acid.
