Definitions

  • the present invention relates to the use of a lipase-containing composition for cleansing soft contact lenses, a water-soluble solid contact lens care composition and the use of a lipase as a means for removing metabolic deposits on or in a soft contact lens or assisting cleaning of the soft contact lens in a water-soluble, solid contact lens care products.
  • contact lenses are still very popular with people with ill health.
  • a problem with the use of contact lenses is still their proper care.
  • a variety of different systems are known, which have in common that a disinfection of the contact lens after wearing the contact lens, usually overnight, whereby the disinfection is effected by chemical agents that must be neutralized due to their aggressive properties before the contact lens can be worn again.

  • a protease Subtilisin is called.
  • the removal of metabolic deposits, particularly protein deposits, on or in the contact lens matrix is extremely important, as these deposits lead to changes in the lens matrix, ranging from changes in optical properties to inflammation.
  • EP 009374 already describes tablets for the cleaning of contact lenses, which contain trypsin, alpha-amylase and a lipase.
  • WO 98/37921 A1 relates to a contact care agent which, in addition to a peroxide-degrading enzyme such as catalase, contains the protease subtilisin and liberates these enzymes in an aqueous solution for the purpose of cleaning contact lenses.

  • EP 0279401 A2 discloses the use of pancreatic lipase as well as microbiological lipases for the removal of deposits in contact lenses.
  • WO 79/00963 A1 discloses the use of lipolytic enzymes for cleaving lipids into fatty acids and alcohols.
  • cholesterol deposits have proven to be persistent.
  • the present invention is based on the surprising discovery that the use of a lipase which is obtainable from Candida rugosa leads to the removal of deposits, in particular cholesterol-containing deposits, which can not be removed satisfactorily with conventional contact lens care products.
  • the present invention therefore provides a lipase-containing composition for cleaning contact lenses, in particular soft contact lenses, characterized in that the composition contains a lipase obtainable from the yeast Candida rugosa. This is also referred to as a pancreatic lipase.
  • Lipase is an enzyme that breaks down fats (triglycerides). The lipase is also responsible for the hydrolysis of retinyl esters to retinol and fatty acids.
  • cholesterol-containing deposits in soft, hydrophilic contact lenses can be removed by the lipase present in the composition according to the invention, although cholesterol is not a triglyceride and also has no structural element which is usually attacked by lipases.

  • the use of the composition takes place in a simple manner in that it acts in aqueous solution on the contact lenses to be cleaned.
  • the aqueous solution is advantageously buffered to aid the activity of the lipase.
  • the ionic strength of the solution can be adjusted in particular by the buffer salts or other constituents present in such a way that it does not impair the activity of the lipase, but advantageously it optimizes it.
  • the buffer salts for adjusting a pH which is favorable for the activity of the lipase can be present in an aqueous phase into which the composition to be used according to the invention is added.
