Ophthalmic optics - Ophthalmic viscosurgical devices
1 Scope
This standard specifies requirements with regard to safety for the intended performance, design attributes, design evaluation, sterilization, product packaging, product labelling and information supplied by the manufacturer of ophthalmic viscosurgical devices.
This standard is applicable to ophthalmic viscosurgical devices (OVDs), a class of substances 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 intra-ocular tissues and to manipulate tissues during surgery.
