A new, rapid hydrogen peroxide system for contact lens disinfection

A new, rapid hydrogen peroxide system for contact lens disinfection

Clao Journal 10(4): 341-345

This 3-mo., 142-patient study was conducted to determine the safety and efficacy of a new, rapid hydrogen peroxide system for contact lens cleaning. The system consists of 3 components, a disinfecting solution (3% hydrogen peroxide), a neutralizing solution, and a lens case; it chemically disinfects all soft lenses in 20 min.sbd.with a 10-min disinfection step followed by a 10-min neutralization step. The neutralizer and the neutralization by-products are harmless substances that occur naturally in the body. The system does not contain thimerosal, chlorhexidine, or other known sensitizing preservative agents. During the study, patients used the system for cleaning, rinsing, neutralizing and storing their daily-wear and extended-wear lenses. Lens wearing time either stayed the same or increased on both daily and extended-wear regimens, visual acuity remained stable, and there was no significant increase in positive slit lamp findings. Patients [13/16] with presumed thimerosal sensitivity completed the 3 mo. and did very well on the regimen. Patients found the system comfortable and convenient to use.
