Because of the high water content, heat disinfection cannot be used with Frequency 55 Toric Contact Lens. A
chemical disinfection system (not heat) must be used. The above table of recommended solutions is no exclusive.
The selection of solutions best suited to the patient should be determined by the eye care practitioner.
Chemical (Not Heat) Disinfection
• Clean the contact lenses with a recommended cleaning solution and thoroughly rinse them with a
recommended rinsing solution.
• Disinfect after cleaning. Carefully follow the instructions accompanying the disinfection solution in the care
regimen recommended by the lens manufacturer or the eye care practitioner.
• When using hydrogen peroxide lens care systems, the lenses must be neutralized before wearing. Follow the
recommendations on the hydrogen peroxide system labeling.
• Thoroughly rinse the lenses with a fresh solution recommended for rinsing before inserting or wearing, or follow
the instructions on the disinfection solution labeling.
• Do not heat disinfect the lenses. Repeated heat disinfection will cause irreversible damage.
• Leave the lenses in the unopened storage case until ready to put on the eye.
• Caution: Lenses that are chemically disinfected may absorb ingredients form the disinfecting solution which
may be irritating to the eyes. A thorough rinse in fresh sterile saline solution prior to placement on the eye
should reduce the potential for irritation.
Lens Deposits and Use of Enzymatic Cleaning Procedure
Enzyme cleaning may be recommended by the eye care practitioner. Enzyme cleaning removes protein deposits on
the lens. These deposits cannot be removed with regular cleaners. Removing protein deposits is important for the
well-being of the patient’s lenses and eyes. If these deposits are not removed, they can damage the lenses and
cause irritation.
Enzyme cleaning does NOT replace routine cleaning and disinfecting. For enzyme cleaning, the patient should
carefully follow the instructions in the enzymatic cleaning labeling.
Lens Case Cleaning and Maintenance
Contact lens cases can be source of bacteria growth. Lens cases should be emptied, cleaned, rinsed with solutions
recommended by the lens case manufacturer and allowed to air dry. The lens cases should be replaced at regular
intervals as recommended by the lens case manufacturer or by the eye care practitioner.
Care for a Dried Out (Dehydrated) Lens
If the Frequency 55 Toric Contact Lens is left off the eye and exposed to air for 30 minutes or longer, it will become
dry and brittle (dehydrated). Handle a dehydrated lens carefully. Place the lens in its storage case and SOAK the
lens in the recommended rinsing and storage solutions for a minimum of 30 minutes. Soak the lens until it returns to
