Best Hygiene Practices with Scleral Lens Wear: Step-by-Step Protocols That Actually Work
Proper hygiene is the single most important factor in safe scleral lens wear. Following a consistent, evidence-based routine dramatically reduces your risk of serious eye infections, including corneal ulcers and sight-threatening conditions.
Key Takeaways
Always wash hands with mild, fragrance-free soap before handling scleral lenses.
Use a solution recommended by your eye care provider.
Never rinse lenses or fill the bowl with any water, including tap, bottled, or distilled. Water exposure is associated with Acanthamoeba keratitis, a corneal infection that is notoriously difficult to treat.
Replace your lens case every 1-3 months and clean it daily to reduce contamination risk.
Schedule regular professional check-ins to catch fit or hygiene issues early.
Why Hand Hygiene Is the Starting Point for Every Scleral Lens Session
Before you touch your lenses, your hands must be completely clean. Wash with a mild, fragrance-free, lotion-free soap for at least 20 seconds, then rinse thoroughly and dry with a lint-free towel. Residue from moisturizers, hairspray, sunscreen, or scented soaps can transfer onto the lens surface and directly into the fluid reservoir that sits against your cornea.
This matters more with scleral lenses than with soft lenses because the bowl of saline solution that fills the lens creates direct, prolonged contact with the eye's surface. Any contamination you introduce during handling does not simply evaporate; it sits on your cornea for hours. In a CDC survey of contact lens wearers, approximately 99% reported at least one hygiene behavior that put them at risk for an eye infection, making handling the most common entry point for infection.
Daily Cleaning and Disinfection
You should use the solution recommended by your eyecare provider. However, if you were told to use a hydrogen peroxide-based solution, it requires a minimum soak time of 6 hours. This is not a shortcut-friendly process. The peroxide must fully neutralize in the specialized standing case before the lens touches your eye. Skipping or shortening the neutralization cycle may causes chemical burns to the cornea.
A complete daily care regimen for scleral lens wearers may include these steps:
Daily surfactant cleaner: After removing lenses for the day, rub each lens for 1-2 minutes with a dedicated cleaning solution to physically remove protein, lipid, and mucin deposits.
Multipurpose or hydrogen peroxide disinfection: Upon removal, multipurpose solutions are used to rinse and rub both front and back surfaces of the scleral lens before soaking in fresh solution overnight. For hydrogen peroxide solution (such as Clear Care®), submerge the lens in a peroxide system case for at least 6 hours, allowing full antimicrobial activity against bacteria, fungi, and protozoa.
Preservative-free saline rinse: Before insertion, rinse lenses thoroughly with a sterile, preservative-free saline or dedicated filling solution. Never use multipurpose soft lens solution, tap water, or distilled water as a substitute. This step can be skipped if using a fully neutralized hydrogen peroxide solution.
For patients managing conditions like keratoconus or severe dry eye, consistent hygiene carries elevated importance because the ocular surface is already compromised. Discuss your specific routine with your fitter.

Solution Management: What You Use and When You Use It
Every day means fresh solution, no exceptions. Topping off existing solution in your case dilutes the disinfectant concentration and significantly reduces its effectiveness. Empty your case completely, rinse it with fresh solution (not water), and let it air dry face-down on a clean tissue.
The danger of tap water cannot be overstated. Acanthamoeba, a microscopic organism found in municipal water supplies, swimming pools, and even well water, can adhere to contact lenses and cause Acanthamoeba keratitis, a painful and difficult-to-treat infection. The CDC's contact lens health resources outline this risk in detail and confirm that tap water exposure is one of the leading preventable causes of lens-related eye infections.
Single-use vials of non preserved saline are the gold standard for filling the scleral lens bowl before insertion. Preserved saline can cause ocular surface irritation with repeated daily exposure.
Lens Case Care and Replacement Timeline
Most lens wearers overlook the case itself. Research indicates that contamination has been found in 23% to 81% of lens cases across studies, with cases older than 9 months carrying the highest contamination rates. Your recommended routine:
Rinse the case with fresh disinfecting solution after each use (never tap water)
Rub the inside of the case with a clean finger to remove biofilm
Air dry face-down on a lint-free surface with the caps off
Replace the case every 1-3 months, or immediately if you notice discoloration, deposits, or visible damage

Protein and Deposit Management for Scleral Lens Wearers
This is where scleral lenses differ from standard soft or rigid gas permeable (RGP) lenses in an important way. The moisture chamber design means that tears, mucin, and proteins are constantly in contact with the inner bowl of the lens. Lipid and protein deposits accumulate faster as a result, affecting optical clarity and comfort.
Weekly enzyme treatments or more frequent surfactant cleaning cycles are often recommended for heavy depositors. If you notice fogging or reduced vision quality midday, deposits may be the cause. This is a conversation worth having with your specialist, and you can explore the services at Texas Contact Lens Institute to review the specialty fitting options and lens care guidance available.
Insertion, Removal, and the Tools That Help
Scleral lenses require a plunger-style insertion tool and a removal plunger. Keeping these tools clean is part of your hygiene protocol. Rinse your plunger with fresh saline before and after each use and replace it every 1-3 months.
Avoid inserting or removing lenses over an open drain. A folded clean towel placed in your sink creates a safer landing zone if the lens is accidentally dropped. Avoid any contact with tap water.
You should also remove lenses before swimming in any body of water, including pools, hot tubs, lakes, and oceans. Waterborne pathogens and chlorine residue both pose risks to lens integrity and eye safety.
Recognizing Contamination and Knowing When to Seek Help
Infection warning signs include increased redness, light sensitivity, unusual discharge or tearing, blurred vision, or significant pain. If any of these appear, remove your lenses immediately and contact your eye care provider without delay. Do not attempt to self-diagnose.
The Mayo Clinic's guide on contact lens-related eye infections outlines the full symptom picture and reinforces when professional evaluation is urgent.

Things to Know
Smoking is a documented risk factor for contact lens-related infections — quitting reduces this risk meaningfully.
Travel hygiene requires extra planning: bring single-use saline vials, a clean spare case, and avoid filling lenses with hotel tap water.
Preservative-free drops, not regular artificial tears, should be used while wearing scleral lenses to avoid overexposure to preservatives.
Lens cases 9 months or older carry the highest contamination rates, making timely replacement non-negotiable.

Frequently Asked Questions
Q: Can I rinse my scleral lenses with tap water in an emergency?
No — tap water should never contact scleral lenses under any circumstances.
Tap water contains Acanthamoeba and other pathogens that can adhere to the lens and cause severe, vision-threatening infections. Carry a spare vial of preservative-free saline when traveling as your backup option.
Q: How often should I replace my scleral lens case?
Replace your lens case every 1 to 3 months, or sooner if it shows any visible contamination.
Lens cases are among the most overlooked hygiene factors. Biofilm builds up inside the case walls even with daily rinsing, and older cases have measurably higher contamination rates.
Q: Why do my scleral lenses fog up during the day?
Midday fogging is most commonly caused by lipid or mucin deposits entering the moisture chamber.
This can result from incomplete daily cleaning, a poorly fitting lens, or underlying dry eye. Discuss the issue with your specialist, as a fitting adjustment or cleaning protocol change often resolves it.
Q: Is hydrogen peroxide disinfection really necessary, or can I use multipurpose solution?
Always use the recommended solution suggested by your eye care provider. However, in general, hydrogen peroxide systems provide deeper disinfection and are often preferred for scleral lenses.
Never use multipurpose solutions are formulated for soft lenses as they are incompatible for rigid scleral materials and can leave preservative residue that irritates the eye through the prolonged scleral lens moisture chamber.
Q: How do I know if my scleral lens hygiene routine is working?
Comfortable, clear vision with no redness, discharge, or sensitivity throughout the day or on removing the lenses suggests your routine is effective.
Regular check-in appointments are the most reliable confirmation. Your provider can inspect lens surfaces for deposit buildup and assess the ocular surface for early signs of irritation before symptoms escalate.
