Abstract

Background: Corneal infections due to contact lens contamination are risks associated with contact lens wear. Care systems which reduce these risks are desirable.

Methods: This study evaluated a contact lens cleaning device using normal saline initially and then four contact lens solutions.

Results: Using saline, six out of 10 tests resulted in complete removal of challenge organisms or showed reductions to 10 cfu/ml or <10 cfu/ml. Tests upon organism using multipurpose solutions showed >6 log reductions in 2-3 minutes. With laboratory made biofilms, similar results were obtained.

Conclusions: This device improves lens cleaning and enhances lens care solutions. When used correctly it should lead to significant reductions in microbial keratitis associated with inadequate contact lens hygiene.
