Ophthalmic implants - Ophthalmic viscosurgical devices (ISO 15798:2022)
This document is applicable to ophthalmic viscosurgical devices (OVDs), a class of surgical invasive medical devices with viscous and/or viscoelastic properties, intended for use during surgery in the anterior segment of the human eye. OVDs are designed to create and maintain space, to protect intraocular tissues and to manipulate tissues during surgery.
This document specifies requirements with regard to safety for the intended performance, design attributes, preclinical and clinical evaluation, sterilization, product packaging, product labelling and information supplied by the manufacturer of these devices.
Ophthalmische Implantate - Viskoelastische Substanzen (ISO 15798:2022)
Dieses Dokument ist anwendbar für ophthalmische viskoelastische Substanzen (OVD, en: ophthalmic viscosurgical devices), eine Klasse chirurgischer invasiver Medizinprodukte mit viskosen und/oder viskoelastischen Eigenschaften, die für den Einsatz bei chirurgischen Eingriffen im Vorderabschnitt des menschlichen Auges bestimmt sind. OVDs dienen dazu, Raum zu schaffen und zu erhalten, intraokulares Gewebe zu schützen und Gewebe während des chirurgischen Eingriffs zu manipulieren.
Dieses Dokument legt Anforderungen bezüglich der Sicherheit für die beabsichtigte Leistung, Konstruktionsmerkmale, an vorklinische und klinische Bewertungen, Sterilisation, Produktverpackung, Produktkennzeichnung und die Bereitstellung von Informationen durch den Hersteller dieser Produkte fest.
Implants ophtalmiques - Dispositifs ophtalmiques viscoélastiques (ISO 15798:2022)
Le présent document s'applique aux dispositifs ophtalmiques viscoélastiques (OVD), une catégorie de dispositifs médicaux invasifs de type chirurgical présentant des propriétés de viscosité et/ou de viscoélasticité, destinés à une utilisation en chirurgie dans le segment antérieur de l'œil humain. Les OVD sont conçus pour créer et maintenir de l'espace, pour protéger les tissus intraoculaires et manipuler les tissus au cours d'interventions chirurgicales.
Le présent document spécifie les exigences en matière de sécurité pour l'utilisation prévue, les caractéristiques de conception, l'évaluation préclinique et clinique, la stérilisation, l'emballage du produit, l'étiquetage du produit et les informations fournies par le fabricant de ces dispositifs.
Očesni vsadki (implantati) - Očesni kirurški pripomočki (ISO 15798:2022)
Ta dokument se uporablja za očesne kirurške pripomočke (OVD) (razred kirurško invazivnih medicinskih pripomočkov z viskoznimi in/ali viskoznoelastičnimi lastnostmi), ki so namenjeni za uporabo med operacijo v frontalnem segmentu človeškega očesa. Očesni kirurški pripomočki so namenjeni ustvarjanju in vzdrževanju prostora, zaščiti tkiv znotraj očesa in manipulaciji tkiva med operacijo. Ta dokument določa zahteve glede varnosti za predvidene lastnosti, atribute načrtovanja, predklinično in klinično vrednotenje, sterilizacijo, pakiranje izdelkov, označevanje izdelkov in informacije, ki jih dobavlja proizvajalec teh pripomočkov.
