Which sequence best describes the GP lens care cycle?

• A. Disinfectant, cleaner, rinse, rewetting drops
• B. Rinse, disinfectant, cleaner, rewetting drops
• C. Rewetting drops, cleaner, rinse, disinfectant
• D. Cleaner, rinse, disinfectant, periodic cleaner

Answer: (D)

The main idea is to clean the lens first to physically remove deposits, then rinse away any cleaner residue, then disinfect to kill microbes, and finally use a periodic cleaner as an occasional maintenance step to remove buildup. Cleaning first ensures the lens surface is actually ready for disinfection and won’t shield microbes or leave deposits behind. Rinsing after cleaning prevents residual cleaner from interfering with disinfection or causing irritation. Rewetting drops are used for lubrication during wear, not as part of the cleaning/disinfection sequence, so they don’t belong in the standard care cycle. The periodic cleaner is an extra maintenance step for deposits that accumulate over time, used as needed rather than daily.
