Evaluation of thermal disinfection procedures for hydrophilic contact lenses.
نویسندگان
چکیده
The kinetics and efficacy of moist heat disinfection for hydrophilic contact lenses were investigated by using representative microorganisms of ophthalmic concern and several heat-resistant species. In replicate challenges, 80 degrees C for 10 min and 75 degrees C for 5 min were proven efficacious for moist-heat disinfection.

Observation of soft contact lens disinfection with fluorescent metabolic stains.
A rapid fluorescent staining method using a tetrazolium dye and propidium iodide for the in-use assessment of disinfection of Pseudomonas aeruginosa biofilms on soft contact lenses showed that 11 to 13% of cells on lenses remained actively respiring and recoverable by culture methods after 30 min of exposure to 3% hydrogen peroxide.

متن کاملEffect of Low Energy Surface Vibration on the Anti-adhesive Properties of Multipurpose Solutions
Contact lenses are a successful form of vision correction. But their use has been associated with an increased risk of microbial keratitis (MK), contact lens related acute red eye (CLARE) as well as contact lens peripheral ulcer (CLPU) (Eltis, 2011). One of the main problems associated with contact lenses is microbial contamination of the lens surface. Microbial contamination further leads to t...
