18、 is a list of general and specific terms relating to contact lens care products. It is not intended to be a comprehensive listing of all possible terms relating to these products. This section does, however, contain the important terms and definitions applicable to contact lens care products which h
19、ave been defined and used within the text of other national and international standards. In the interest of international harmonization, whenever possible, the terms and definitions have been harmonized with those used in international standards. 3.1 General Terms Relating to Contact Lens Care Produ
20、cts Reference: ISO 18369-1: Ophthalmic optics Contact lenses Vocabulary, classification system, and recommendations for labelling 3.1.1 Active ingredient: Component present in sufficient quantity that relates to an intended purpose. 3.1.2 Antimicrobial activity: Ability to kill/destroy/inactivate mi
21、croorganisms, prevent their proliferation and/or prevent their pathogenic action. 3.1.3 Antimicrobial agent: Compound capable of antimicrobial activity. 4 ANSI Z80.18-2016 3.1.4 Aseptic processing: Handling of sterile product, containers and/or devices in a controlled environment, in which the air s
22、upply, materials, equipment and personnel are regulated to maintain sterility NOTE This includes sterilization by membrane filtration that cannot be separated from the subsequent aseptic process (ISO 13408-1). For aseptic processing, there is not a sterility assurance level but a maximum contaminati
23、on rate (determined by media fill validation). 3.1.5 Batch: Defined quantity of bulk, intermediate or finished product that is intended or purported to be uniform in character and quality, and which has been produced during a defined cycle of manufacture (ISO 11137-1). 3.1.6 Bioburden: Population of
24、 viable microorganisms on a raw material, component, a finished product and/or a package (ANSI/AAMI/ISO 17665-1). NOTE Bioburden is expressed as the total viable count (TVC), or colony forming units (CFU, cfu) per lens or tablet, or CFU per ml of solution. 3.1.7 Container Closure Integrity: The phys
25、ical capability of a given package to protect its contents with the desired level of protection over a defined period of service. A barrier to physical, microbiological or chemical challenges. (ASTM F17-13a) 3.1.8 Expiration date or expiry date: Period of time, designated by the manufacturer, beyond
26、 which the product should not be first used. 3.1.9 Inoculum: Suspension of known organisms. 3.1.10 Intended purpose: Use for which a device is intended according to the information supplied by the manufacturer on the labeling, in the instructions and/or in promotional materials. 3.1.11 Labeling: All
27、 information given on any label, the primary container, the secondary carton or in a leaflet supplied with the product. 3.1.12 Performance: Suitability of a device to achieve its intended purpose. 3.1.13 Preservative: Component intended to prevent the growth of microorganisms on a product. 3.1.14 Pr
28、imary packaging or primary container or shipping package: Element of the packaging system that maintains the sterility or cleanliness of the product (ANSI/AAMI/ISO 17665-1). NOTE Primary packaging is intended for storage and protection of the finished product for the duration of the labeled shelf-li
29、fe or until the integrity of the package has been compromised. 3.1.15 Shelf life: Specified period of time from the date of manufacture of a product to its labeled expiration date. 3.1.16 Stasis: Inhibition of microbial growth. 3.1.17 Sterile: Free of viable micro-organisms (ANSI/AAMI/ISO 11135-1).
30、NOTE In practice no such absolute statement regarding the absence of micro-organisms can be proven. The nature of microbial death is described by an exponential function. Therefore, the presence of viable micro-organisms on any individual item can be expressed in terms of probability. Although this
31、probability may be reduced to a very low number, it can never be reduced to zero. 3.1.18 Sterility assurance level (SAL): Probability of a single viable microorganism being present on a product unit after sterilization (ANSI/AAMI/ISO 11135-1). NOTE SAL is normally expressed in the form 10-n. When ap
32、plying this quantitative value to assurance of sterility, an SAL of 10-6 has a lower numerical value but provides a greater assurance of sterility than an SAL of 10-3. 5 ANSI Z80.18-2016 3.1.19 Tamper-evident package: Package having an indicator or barrier to entry which, if damaged, breached or mis
33、sing, can reasonably be expected to provide evidence to practitioners or users that the package may have been opened. 3.2 Specific Terms Relating to Contact Lens Care Products 3.2.1 Abrasive cleaner: Suspension in sufficient concentration used to facilitate cleaning of contact lenses by friction enh
34、ancement. 3.2.2 Blister pack: Disposable primary container consisting of a thin molded depression of material containing a product sealed with appropriate material. 3.2.3 Conditioning solution: Liquid preparation formulated for soaking and storage of a contact lens for the intended purpose of mainta
35、ining the lens in a condition suitable for reuse. NOTE Conditioning solutions are generally formulated with antimicrobial agents and primarily intended for use in the hygienic management of rigid contact lenses. 3.2.4 Contact lens care regimen: Series of processes specified by the lens or care produ
36、ct manufacturer and used by the lens wearer to maintain ocular health, lens condition, comfort and vision. 3.2.5 Contact lens cleaning: Process of removing surface contaminants from a contact lens. NOTE Cleaning is usually the first step in the hygienic management of a reusable contact lens. Chemica
37、l agents (e.g., surfactants) are often employed in contact lens cleaning products to facilitate the removal of foreign matter from a contact lens. 3.2.6 Contact lens accessory: Article intended specifically by its manufacturer to be used with a contact lens to enable the lens to be used in accordanc
38、e with its intended purpose. 3.2.7 Contact lens care product: Contact lens accessory intended for use in maintaining the safety and performance of a contact lens after opening and removal of the lens from its original shipping package. NOTE This term includes all devices recommended for use in the h
39、ygienic management of contact lenses, for hydrating contact lenses, or for alleviating discomfort of contact lens wear by physical means. 3.2.8 Contact lens disinfecting agent(s): Chemically or physically active ingredient(s) in contact lens disinfection. 3.2.9 Contact lens disinfection: Chemical or
40、 physical process to reduce the number of viable microorganisms on a contact lens to a level which is neither harmful to ocular health nor to the quality of contact lenses and accessories. NOTES (1) Bacterial spores, Acanthamoeba and some viruses may not necessarily be inactivated during the contact
41、 lens disinfection process. (2) See ISO 14729 for definitions for “contact lens disinfecting product” and “contact lens disinfecting regimen” and requirements associated with these terms. 3.2.10 Contact lens disinfecting product: Product that possesses biocidal activity (kills, destroys or inactivat
42、es), meeting the primary criteria of the stand-alone test specified in ISO 14729. 3.2.11 Contact lens disinfecting regimen: Contact lens care regimen designed to meet both the secondary criteria of the stand-alone test and the regimen test in ISO 14729. 3.2.12 Contact Lens Rinsing: Act of removing p
43、hysical and chemical contaminants from a contact lens by allowing the flow of a suitable liquid over the surfaces of the lens. 6 ANSI Z80.18-2016 NOTE A minimum time for rinsing lenses is generally recommended by the manufacturer in the labeling of a rinsing solution to achieve its intended purpose.
44、 3.2.13 Discard date or in-use period (deprecated): Specified period of time from first use when a products continued use should cease. 3.2.14 Enzymatic cleaner protein remover: Liquid or solid preparation containing one or more enzymes as active ingredients with the intended purpose of reducing ads
45、orbed and absorbed proteins and/or lipids on a contact lens. NOTE Enzymatic cleaners are optional lens care products recommended for use in the hygienic management of contact lenses. 3.2.15 Hygienic management: Procedure by which contact lenses are maintained in a condition for safe reuse. 3.2.16 In
