Mechanism
of Action
The compact electronic PuriLens System cleaning and disinfecting unit uses subsonic
agitation in combination with a germicidal UV light to clean and disinfect soft
contact lenses. The subsonic agitation removes lens deposits and microorganisms.
The UV light disinfects by killing the microorganisms in the solution. Lenses
are held safely in the color-coded PuriLens lens holder.
Technical Specifications
Cleaning
PuriLens
cleans lenses by creating hydrodynamic shear with preservative-free PuriLens Solution
that lifts daily accumulations of lipids, mucin, protein, and other debris from
the lens surface. The hydrodynamic shear is generated by subsonic agitation at
3600 cycles per minute.
Disinfecting
Microorganisms
are irradiated with UV-C at 253.7 nm = 1000 µw/cm2 at one inch
for 15 minutes. The UV radiation is absorbed by the microorganism's DNA, causing
cross-linking and breaking of the nucleic acid bonds. This results in rapid death
of microorganisms.
