Which statement best describes the Boston One-Step Enzymatic Cleaner?

• A. It is an enzymatic cleaner and must be rinsed off after use.
• B. It is a disinfectant wipe.
• C. It uses polyquad as preservative.
• D. It is used daily

Answer: (A)

Enzymatic cleaners are used to break down protein deposits on lenses, doing a dedicated cleaning job separate from disinfection. The Boston One-Step Enzymatic Cleaner is designed for that purpose, so the best description is that it is an enzymatic cleaner and must be rinsed off after use. The enzyme works to digest deposits while the rinse removes any enzymatic residue so the eye isn’t irritated by leftover enzyme when you insert the lens. It isn’t a disinfectant wipe, and it isn’t defined by a preservative like Polyquad. It’s also not generally used daily; enzymatic cleaning is typically done periodically (often weekly or as prescribed) rather than as a daily routine.
