Greater lens care compliance observed with patients using hydrogen peroxide
A recent paper in Contact Lens Spectrum by my good friends and colleagues Jill Woods and Lyndon Jones – based on a study done in the Centre for Ocular Research and Education (CORE) at the University of Waterloo in Canada – looked at the difference in lens care compliance between users of hydrogen peroxide and multipurpose solution (MPS) care regimens. In their paper, Jill and Lyndon note that patients frequently engage in non-compliant behavior when caring for their lenses, including failure to use the care regimen recommended by their optometrist, failure to rub and rinse their lenses prior to disinfection with a MPS regimen, and failure to use fresh solution or “topping off” their solution prior to the disinfection cycle.
MPS regimens are more commonly used for lens care in contact lens practice, however over the last 10 years, there has been an upsurge in the use of hydrogen peroxide for contact lens maintenance, especially with the increased use of silicone hydrogel contact lenses which do tend to deposit more due to the incorporation of silicone into the lens material. Hydrogen peroxide is a great problem solver and we are using it more and more in our practice. It has excellent disinfection properties and it is very effective in helping to minimize the degree of protein and lipid deposition on the contact lens surface.
The results of Jill and Lyndon’s study clearly showed that users of hydrogen peroxide care regimens were more compliant with their contact lens care procedures than users of MPS regimens. Hydrogen peroxide users – when compared to MPS users – were more compliant with respect to returning to their contact lens practitioner at shorter intervals, not switching from the lens care brand recommended by their practitioner, not “topping-up” their cleaning solution and replacing their contact lens case within the recommended three months. As Jill and Lyndon conclude in their paper “prescribing a hydrogen peroxide care regimen is a strategy that should be considered to improve overall compliance with reusable soft lens care” and I would strongly concur with this recommendation.
