To clean scleral lenses effectively, you need a thorough and consistent cleaning routine to ensure their longevity and to avoid eye infections.
Proper cleaning also guarantees clear vision and optimum comfort throughout the day.
Unlike typical contact lenses, scleral lenses require more care due to their larger size and specialised materials. Whether you’re a seasoned wearer or new to scleral lenses, this guide will walk you through the essential steps and best practices for keeping your lenses clean and safe.
Why Cleaning Scleral Lenses is Crucial?
Properly cleaned scleral lenses not only improve comfort but also safeguard the health of your eyes. During daily use, your lenses accumulate deposits like proteins, lipids, dust, and environmental debris. Neglecting cleaning routines can lead to foggy vision, discomfort, and even infections.
Improper maintenance might also damage the lenses, reducing their lifespan and increasing replacement costs. By sticking to a proper cleaning routine, you ensure both safety and prolonged usability.
Preparation Before Cleaning Your Scleral Lenses
Wash Your Hands Thoroughly
Always begin by washing your hands with fragrance-free soap and drying them with a lint-free towel. This step is vital to prevent bacteria or debris from transferring onto the lenses. Avoid using oily or moisturising soaps, as they can leave residues that interfere with the lens surface.
Set Up a Clean Workspace
A clean, flat surface ensures optimal hygiene while handling your lenses. Use a clean towel to cushion and catch lenses in case they slip from your hands. Additionally, try to work in an area with good lighting for better visibility.
Gather All Necessary Supplies
Ensure you have the following essential materials:
- Prescribed cleaning solution: Never use tap water as it can harbour harmful microorganisms.
- A saline solution for rinsing.
- A specialised lens cleaning case.
- Clean-protein removal tablets if recommended by your optometrist.
Step-by-Step Guide to Cleaning Scleral Lenses
Step 1. Remove the Lenses Safely
Use a lens removal plunger if advised, or follow the removal technique recommended by your eye care professional. Avoid squeezing the lens too hard, as this can crack or scratch its surface. If you find it difficult to remove the lenses or use a plunger, do not force them. Consult your eye care professional for guidance to avoid damaging the lenses or your eyes.
Step 2. Rinse the Lenses
Once removed, rinse each lens thoroughly with preservative-free sterile saline solution or recommended rinsing solution. This removes loose debris and surface residue.
Step 3. Apply Cleaning Solution
Apply a few drops of a dedicated scleral or rigid gas-permeable (RGP) lens cleaning solution onto the lens. Use your fingertip to gently rub the lens surface in a circular motion for at least 20 seconds, cleaning both sides thoroughly. Avoid using multipurpose soft lens solutions as they are not designed for scleral lenses.
Step 4. Rinse Again
Thoroughly rinse the lens using preservative-free sterile saline solution to eliminate any remaining cleaning solution. This step helps prevent eye irritation during wear.
Step 5. Inspect the Lenses
Before storing, carefully inspect each lens for cracks, scratches, or persistent build-ups. Replace damaged lenses, as they can compromise your eye’s safety and comfort.
Step 6. Store in a Clean Case
Store your lenses in a dedicated storage case filled with fresh, appropriate disinfecting solution specifically designed for scleral or RGP lenses. Do not reuse solution or use tap water in the storage case, as used solution may contain bacteria and impurities that could lead to contamination.
Important Note:
Regularly clean your lens case at least once a week using warm water and leave it to dry upside down on a clean, lint-free surface. Replace the case every three months for optimal hygiene.
Cleaning the Lens Case
Regular cleaning of your lens case is as essential as cleaning the lenses themselves. Dirty cases are a breeding ground for bacteria and fungi that can transfer to your lenses.
Tips for Cleaning a Lens Case:
- Empty used solution daily.
- Clean your case with sterile saline solution or a recommended cleaner—skip the tap water!
- Allow the case to air dry completely before refilling.
Extra tip: Pairing regular lens and case cleaning habits significantly minimises the chances of contamination.
Mistakes to Avoid When Cleaning Scleral Lenses
- Using tap water: Tap water contains bacteria like Acanthamoeba, which can attach to lenses and cause severe infections.
- Skipping daily cleaning: Daily build-up of protein and oils can lead to reduced effectiveness and comfort if not removed.
- Overrubbing the lenses: Excessive force can scratch or damage the lens. Always handle them gently.
- Reusing old disinfecting solution: Used solution lacks the ability to clean effectively and can harbour bacteria.
- Ignoring lens expiry dates: Always follow the recommended replacement schedule for scleral lenses, no matter how clean they seem.
Additional Care Tips for Scleral Lenses
To enhance the protection of your lenses and maintain optimal eye health:
- Use only the cleaning products recommended by your eye care professional.
- Replace cleaning solutions per the instructions on their labels to ensure effectiveness.
- Consult your optometrist immediately if you experience discomfort, cloudy vision, or redness while wearing the lenses.
When to Replace Cleaning Solutions and Tools?
For optimum results:
- Disinfecting solutions: Replace as per the manufacturer’s instructions.
- Lens plunger tools: Replace as they show signs of wear.
- Storage Cases: Replace every three months or sooner if they appear damaged or dirty.
