Non-compliance and microbial contamination in orthokeratology.

摘要: Purpose To determine the rates of microbial contamination solutions and lens accessories existing ortho-k wearers effect on monthly replacement warnings. investigate self-reported levels compliance with care lenses correlation these contamination. Methods Asymptomatic at least 6-month successful use were requested to bring their lenses, solutions, next aftercare visit. All items, except replaced each data collection Samples collected from surface, solution, cultured for pathogens. These procedures repeated twice 1-month intervals. At first visit, subject and/or parent was interviewed about care/use accessories. Results Thirty-eight subjects completed study. Initial cases, tweezers 29, 34, 46%, respectively. Rates dropped suction holders, during three-visit intervention. Contact cleaner contaminated all occasions most product being artificial tears [33% (n = 18)]. There no improvement in rate cases. The common pathogens isolated Staphylococcus aureus Serratia marcescens. Compliance lowest cases highest lenses. However, between reported presence failed reach significance. Conclusions Subjects' awareness importance cleanliness is high can be improved by regular reinforcements. attitudes toward cleaning far less satisfactory while warnings resulted significant improvements more emphasis should placed educating patients correct
