storing CL's for prolonged periods
Jun 30, 2005 20:54:31 what advice do we give to Px's who want to store their lenses (be it soft or RGP) for lets say 1 week. Or even 1 month without wearing them. How often do they change the solution. Does this vary for HP systems. |

Jun 30, 2005 21:36:23 change all in one every week after freshening up the lenses by rubbing them. Wipe the case dry before refilling with solution. I don't think this changes for hydrogen peroxide systems either - acantha cysts can survive in these systems. Best to plan for the worse and hope for the best :-) palfi |

Jun 30, 2005 22:10:11 Thanks...but i thought that the HP solution will break down into water-will this not cause a problem? |

Jul 02, 2005 07:32:53 Hydrogen peroxide will break down into water if you add a chemical catalyst. If you don't it will remain highly effective, even killing Acanthoemeba cysts. However extended soaking in HP risks causing a change in some soft lens parameters. If you use a catalyst to neutralise the HP then you are left with a sterile water solution. |
