Safety Information

GONIOSCOPY LENSES:

Do not use a microfiber cloth, as over time these tend to collect dirt and dust which can damage the anti reflective coating on the lens.

Never use a device that shows any sign(s) of damage.

Failure to follow the point-of-use processing steps could adversely affect further decontamination steps.

Any serious incident that has occurred in relation to the device should be reported to the manufacturer and the competent authority of the member state in which the user and/or patient is established.

A thorough, manual cleaning process is recommended. Corrosive cleaning agents (i.e. acids, alkalines, etc) are not recommended. Detergent cleaning agents with neutral ph are recommended.

Do not use detergents that contain any type of emollients.

Wiping the lens with a microfiber cloth will cause lens damage. Be sure to use only a soft, lint-free
cotton cloth.

Ensure the device is completely submerged in the disinfectant solution for the entirety of the recommended or desired soak time. Do not allow the device to become unsubmerged from the disinfectant solution. Exposure to disinfectant solutions beyond the recommended soak time, and/or exposure to higher concentrations of disinfectant solution, will result in accelerated degradation of most Volk product.

Rings may discolor when exposed to Sodium Hypochlorite or Glutaraldehyde. To avoid further degradation please follow only the disinfection procedures indicated for these products in this document. This color change is purely cosmetic and will not affect the function of the lens.
