Orthokeratology (Ortho-K) lenses are a safe and effective way to correct vision and manage myopia progression in children and teenagers.
It’s important to clean and store your lenses properly to ensure safety and comfort. Improper care can increase the risk of eye infections, corneal ulcers, or long-term eye health issues.
Before Handling Your Ortho-K Lenses
Wash your hands thoroughly with soap (free of moisturisers or perfumes) and dry them with a clean, lint-free towel. Make sure to wash between your fingers and under your nails.
Work in a clean environment – avoid bathrooms, which can harbour germs. Sit at a table with a lint-free cloth to catch the lenses if dropped.
Inspect your lenses before inserting. If you see cracks, chips, or scratches, do not wear them. Damaged lenses can cause discomfort and harm the eye.
Ortho-K Lens Solutions Explained
There are several different types of solutions involved in Ortho-K care, each with a specific role:
Saline solution – Used for rinsing after cleaning and before insertion.
Daily cleaner – Removes dirt and debris when lenses are rubbed gently in the palm of the hand.
Conditioning/disinfecting solution – Kills germs while lenses soak during the day.
Hydrogen peroxide system (3%) – A one-step option that both cleans and disinfects lenses. Once the hydrogen peroxide has fully neutralised (which typically takes at least six hours), the solution becomes a gentle saline, and the lenses are safe to insert directly from the case. Always follow the manufacturer’s instructions, as advised by your optometrist.
Protein remover – May be recommended by your optometrist for use weekly or monthly to dissolve protein deposits that can build up on the lenses.
Note: Hydrogen peroxide should never go directly into the eye. Lenses must be fully neutralised before wearing.
Daily Cleaning Routine
Ortho-K lenses are usually worn overnight and removed each morning. Once removed, they must be cleaned and disinfected before the next use.
Step 1. Clean
Place the lens in the palm of your hand, apply a few drops of approved daily cleaner, and gently rub both sides for at least 20 seconds.
Step 2. Rinse
Thoroughly rinse each lens with sterile saline solution to remove loosened debris and cleaner.
Step 3. Disinfect
Two-step system: Place lenses in a clean lens case filled with conditioning solution and leave to soak until the next wear.
One-step hydrogen peroxide system: Place lenses in the provided case with neutralising disc, fill with peroxide solution, and leave to disinfect for at least 6 hours.
Step 4. Case care
Discard the old solution, rinse the case with fresh conditioning solution, and leave it to air dry. Replace cases every 3 months.
Weekly or Monthly Deep Cleaning
To prevent build-up and maintain comfort:
- Add protein remover to your regular disinfecting solution (check product-specific instructions).
- Soak lenses for the recommended time (from 15 minutes to several hours, depending on product).
- After soaking, rinse thoroughly with saline before wearing.
If you notice redness, pain, or unusual discomfort while wearing Ortho-K lenses, remove them immediately. If symptoms persist after removal, contact your optometrist without delay. Seek urgent care if necessary.
