Cp. Ifejika et al., Efficacy of a contact lens cleaning device and its enhancement of the performance of contact lens care products, BR J OPHTH, 84(5), 2000, pp. 539-541
Backgsound-Corneal infections due to contact lens contamination are risks a
ssociated with contact lens wear. Care systems which reduce these risks are
desirable.
Methods-This study evaluated a contact lens cleaning device using normal sa
line initially and then four contact lens solutions.
Results-Using saline, sh out of 10 tests resulted in complete removal of ch
allenge organisms or showed reductions to 10 cfu/ml or <10 cfu/ml. Tests up
on organism using multipurpose solutions showed >6 log reductions in 2-3 mi
nutes. With laboratory made biofilms, similar results were obtained.
Conclusions-This device improves lens cleaning and enhances lens care solut
ions. When used correctly it should lead to significant reductions in micro
bial keratitis associated with inadequate contact lens hygiene.
