34、ial agents capable of achieving this. It is essential that all liquid contact lens care products are sterile until opened. Dry products (tablets, granules, etc.) should be subject to control of microbial contamination and should be dissolved in a suitable diluent immediately prior to use. Multidose

35、contact lens care products must be adequately preserved or be packaged in a container designed and labelled to minimize the risk of injury resulting from in-use contamination. Contact lenses are normally subject to a regimen of cleaning and contact lens disinfection between periods of wear. Aqueous

36、solutions containing cleaning and/or disinfecting agents are commonly used for this purpose. These products may be marketed as solutions or as tablets for dissolution immediately prior to use in a suitable diluent such as saline. The past 20 years of experience in the use and regulation of contact l

37、ens disinfecting products has shown distinct disinfecting antimicrobial criteria for this class of medical devices. Ocular toxicology concerns, process convenience and product comfort on the eye, have meant an evolution of products which maintain a low incidence of contact lens associated ocular inf

38、ection when used as instructed by the manufacturer. This International Standard gives these distinct contact lens disinfecting antimicrobial criteria along with annexes to explain why viruses (annex C) and Acanthamoeba (annex D) are not included as challenges. Organic soil is not required for evalua

39、tion of contact lens care disinfecting products but may be used; an informative annex (annex E) is included to discuss organic soil in the context of contact lenses and contact lens care products. DIN EN ISO 14729:2011-01 EN ISO 14729:2001 + A1:2010 (E) 51 Scope This International Standard specifies

40、 two test methods for evaluating the antimicrobial activity of products to be marketed for contact lens disinfection by chemical means and for products that are part of a contact lens care regimen. This International Standard is not applicable to the hygienic management of trial lenses. NOTE General

41、 disinfection product standards are not applicable to contact lens care products, e.g. EN 1040:1997 and EN 1275:1997. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated ref

42、erences, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated r

43、eferences, the latest edition of the normative document referred to applies.

47、 individual solutions with a suitable level of antimicrobial activity as contact lens disinfection products. The regimen test is designed to qualify individual solutions as part of a contact lens disinfecting regimen. Products meeting the regimen test criteria shall also meet the minimum performance

48、 requirements of the stand-alone test. It is fundamental that such products (unopened containers) are capable of meeting the requirements of the test throughout their labelled shelf life. As described in Figure 1, contact lens care solutions which are designed to possess disinfecting properties shal

49、l be tested in the stand-alone test first. If the respective primary criteria are met (see 5.1), the product may be labelled as a contact lens disinfecting product. If the product fails the primary criteria of the stand-alone test, the product must exhibit sufficient antimicrobial activity to meet the secondary criteria of the stand-alone test as listed in 5.2. If these secondary criteria are met, the regimen test shall be performed in order to qualify the product as part of a contact lens disinfecting regimen by meeting
