Ortho-k Lens Cleaning

Ortho-K lenses provide safe, effective myopia control and great daytime vision. The most important factors in ensuring safe wearing and the effectiveness of Ortho-K treatment are:
• An eye that is healthy
• A lens that fits properly.
• A wearer who adheres to recommended lens care routines.

As a Contact Lens wearer, your role in ensuring you have a trouble free experience is ultimately most important.
There are three key steps:

1. Cleaning
2. Disinfection & Storage
3. Ongoing Care


Begin by washing your hands properly. To clean an Ortho-K lens, place the lens in the palm of your hand and put a few drops of cleaner on it, then rub the cleaner into the lens for 20 to 30 seconds. Take care not to scratch or damage the lens as ortho-k lenses can break with excessive force. This step removes material that deposits on the lens during wearing.
Intensive Cleaning: Enzyme cleaning is an extra step to remove protein deposits on the lens.
Menicon progent AB or Boston One Step Liquid Enzymatic Cleaner is a simple and convenient way to effectively remove protein deposits. Follow your Doctor’s instruction for cleaning procedures.


After cleaning, store lenses in fresh conditioning solution in your case, ensuring the lens is completely submerged for at least 4 hours. This step kills microbes on your lenses. The lens is now ready to be inserted into the eye.
To increase lens wearing comfort, a few drops of non-preservative lubrication drops can be applied to the lens before insertion. (NEVER store your lenses in tap water, as micro-organisms can cause infections in your eyes.)
After removing the lens from the case, discard the used solution. Rinse the case with hot water each day and allow it to air dry. Once a week the case should be cleaned with cleaner and allowed to air dry. The case must be replaced periodically.


While an ortho-k lens can last for more than a year, longevity will vary depending on the eye condition, proper lens handling and the lens material. Some patients may need to replace their lenses more frequently than others. For this reason, it is important to have the ortho-k lens checked at least once a year. This check will ensure that the surface of the lens, the fit of the lens, and the power of the lens, are all as they should be. If you experience reduced comfort, blurred vision, or find a coating forming on the lens, check with your optometrist. These are signs that your lens may have to be replaced.


The following guidelines are designed to maximize the safety of your ortho-k treatment.
• Always wash hands (with cold cream-free, deodorant-free soap) before handling contact lenses.
• Any time you remove your lenses, always clean and disinfect them before reinserting.
• Follow your consultant’s lens care recommendations exactly.
• Clean and air-dry the contact lens case every day. Wash and clean the lens case once a week.
• Always check with your consultant before changing solutions.
• Replace lens cases periodically.
• Avoid using solution bottles for long periods after they have been opened--check with your consultant for a recommended time to use opened solution bottles--typically 30 to 60 days after opening.
• Never reuse solutions. Discard used solutions immediately.
• Never use saliva to moisten a contact lens; never put a contact lens into your mouth.
• Never use home-made saline.
• Never store contact lenses in non-sterile fluids such as distilled water, tap water, bottled water, or home-purified water.

WARNING SIGNS - If an eye becomes red or uncomfortable while a contact lens is in place, remove the lens immediately. If the problem continues after the lens has been removed, see your eye care professional immediately. Make an emergency appointment if needed.
