Maintenance of the contact lenses consists of three steps, so this is the solution with three functions, 3-in-1:
LENS CARE® solution protects the lenses, does not have a negative effect on the eye, does not damage the lenses and efficiently maintains the hygiene of the lenses. The main ingredient for cleaning is a surfactant – a copolymer of ethylene oxide and propylene oxide, Poloxamer 407 (BASF, Germany) or Lutrol F 127 (ICI Surfactant, USA). It is non-toxic and non-ionic PAM, and it cleans lenses from protein substances and solubilizes lipids and other deposits. It also bonds to the surface of the lens and makes it wet and comfortable to wear.
It is necessary to clean and rinse the lenses in a solution with a pH of 6.6-7.8 and an osmolarity of 280-320 milliosmoles/liter, such as LENS CARE®.
The presence of conservancies in the LENS CARE® solution keeps lenses protected during the storage for up to 30 days, if the lenses are not in use. Traditional conservancies, benzalkonium chloride and thiomersal, are proved themselves as cytotoxic and cause eye irritation. LENS CARE® contains the newer desinficint polyhexanide.
Each packaging of LENS CARE® solution contains a cassette for contact lenses.
The cassette for contact lenses is an integral part of the disinfection system, but is often overlooked by patients. Microorganisms can form a biofilm on the surface of the cassette that becomes resistant to disinfection and attracts other bacteria and impurities. Data show that 40-55% of cassettes are contaminated with bacteria, which is why it is recommended to change them at least every three months, and optimally every month.
