Hydrogen peroxide disinfection of hydrogel contact lenses: An overview

Abstract

Many hydrogen peroxide systems have recently been introduced to the contact lens market. No two systems are identical, and practitioners are confronted with a great deal of information from the various solution companies. When considered en musse, this information is complex and often contradictory. Here, we review the principles of hydrogen peroxide disinfection and neutralization, and critically examine the major differences in the systems with a view to the development of guidelines for the safe and effective use of this disinfecting agent. Attention is drawn to a number of important issues which are yet to be resolved.

Key words:

• hydrogen peroxide
• disinfection
• neutralization
• hydrogel contact lens
