Wetability and deposits accumulation on anterior surface of blue light‐filtering contact lens

Abstract

AbstractPurpose To evaluate wetability and deposits accumulation on anterior surface of blue light‐filtering contact lens after a cleaning process with Multi‐purpose Solution Cleaning, Hydrogen Peroxide solution and Lubricant Drops.Methods A self‐controlled trial was carried out in 41 contact lens users who were wearing blue light‐filtering contact lens (Profilcon A 52%WC) for 30 minutes per test. Wetability and deposits accumulation on anterior surface were evaluated according to the International Organization for Standardization ISO11980 guidelines. Four conditions were set: a)usual contact lens, b)blue light‐filtering contact lens after cleaning process with Multi‐purpose Solution Cleaning, c)after Hydrogen Peroxide solution disinfection and d) after Lubricant Drops instillation.Results Statistically significant differences were not observed within the parameters evaluated among the different cleaning solutions proposed. For a,b,c and d conditions, the percentage of lens that showed very insignificant deposits accumulation(visible after drying tear film) were 25%,34%,20% and 27%, respectively and the percentage of lens that showed not significant deposits (deposits easily eliminated) were 3%,2%,7% and 8%, respectively. Regarding wetability, minor wetability problems were showed and these ones were solved by the blinking in 18%, 29%, 18% and 18% of the cases, respectively, whereas the areas that remained dry on the contact lenses were 4%,0%,5% and 2% of the cases.Conclusion The wetability and deposits accumulation on anterior surface of blue light‐filtering contact lenses is similar for the different cleaning treatment and equivalent to the non blue light‐filtering contact lens.
