Measuring Prism S12-18 features an integrated structure that reduces infection risk. Its environmentally conscious design is ideal for re-use, and enables highly accurate and safe intraocular pressure measurement. Methacrylic resin, one of the hardest and most highly transparent optical-use plastic materials, is used to realise brightness and clarity of observation and to product life.
Smart Structure
Since the prism part (grey part on the figure) including the side surface is an integrated structure, there is a lower risk of infection from the residual left in the boundary which some manufacturers use their measuring prism for.
How to disinfect S12-18
We recommend using following disinfectants to disinfect S12-18.
Please adhere to the instruction provided with each disinfectant regarding the method of use and precautions of the disinfectant. For the method of manual cleaning and disinfecting the S12-18, please follow the instruction enclosed in the package of the product.
If the above disinfectants are not available, the following disinfectants can be used. The concentration does not indicate the bactericidal effect of the disinfectant, but indicates the range in which the prism body can withstand each disinfectant.
Please note that the effect of disinfection is the responsibility of the user.
Do not use disinfectants containing alcohol as they will damage the prism body.
Please note that the warranty does not cover damage to the prism body using disinfectants not listed in the instruction manual or this disinfectant list.
