Scleral Lens Cleaning: A Comprehensive Guide
Scleral lenses offer unparalleled visual correction for individuals with complex refractive errors or corneal irregularities. However, their intricate design and extended wear necessitate meticulous cleaning and disinfection to maintain eye health and lens longevity. This comprehensive guide will walk you through the proper techniques for scleral lens care, addressing common questions and concerns.
Why is Proper Scleral Lens Cleaning So Important?
Neglecting proper scleral lens cleaning can lead to several serious complications. Accumulated debris, protein deposits, and microorganisms can cause discomfort, infections (such as microbial keratitis), and even vision impairment. Regular and thorough cleaning prevents these issues, ensuring both comfort and the safety of your eyes.
What are the Necessary Supplies for Scleral Lens Cleaning?
Before you begin, gather the following essential supplies:
- Lens Case: A specifically designed scleral lens case is crucial. Regular contact lens cases are insufficient.
- Multi-Purpose Solution (MPS): Select an MPS specifically recommended by your eye care professional for scleral lenses. Not all solutions are created equal, and some may damage the lens material.
- Lens Cleaning Solution: Some eye care professionals recommend a separate enzymatic cleaner for protein removal in addition to MPS.
- Soft, Lint-Free Microfiber Cloth: Avoid using paper towels or tissues, as these can scratch the lens surface.
- Sterile Saline Solution: This is used for rinsing the lens.
- Lens Cleaning Brush (Optional): A soft-bristled brush can be helpful for removing stubborn debris.
How to Clean Your Scleral Lenses: A Step-by-Step Guide
- Thorough Handwashing: Begin with scrupulous handwashing using soap and water. Dry your hands with a lint-free towel.
- Lens Removal: Carefully remove your scleral lenses following your eye doctor's instructions.
- Initial Rinse: Rinse your lenses thoroughly with sterile saline solution to remove loose debris.
- Cleaning with MPS: Fill your lens case with the recommended amount of MPS. Submerge each lens completely, ensuring all surfaces are covered.
- Soaking: Allow the lenses to soak in the MPS for at least four hours, or overnight as directed by your eye doctor.
- Protein Removal (If Applicable): If using an enzymatic cleaner, follow the manufacturer's instructions carefully. This step usually involves soaking the lenses in the enzymatic solution for a specified period.
- Final Rinse: After soaking, gently rinse each lens again with sterile saline solution.
- Inspection: Carefully inspect each lens for any remaining debris or damage before reinsertion.
- Lens Insertion: Insert the lenses following your eye care professional's instructions.
How Often Should You Clean Your Scleral Lenses?
You should clean your scleral lenses daily. This is crucial for maintaining hygiene and preventing complications.
What are the Signs of Improper Scleral Lens Cleaning?
Signs of improper cleaning may include:
- Discomfort or irritation: Redness, burning, or itching are common indicators.
- Blurred vision: This could be due to debris obstructing your vision.
- Increased mucus production: Excess mucus may suggest an infection or irritation.
- Persistent dryness: Incomplete cleaning can lead to dryness.
Can I Use Regular Contact Lens Solution for Scleral Lenses?
No. Regular contact lens solutions are not formulated for the unique material and design of scleral lenses and may damage the lens or cause eye irritation. Always use a solution specifically recommended by your eye doctor.
What if I accidentally damage my scleral lens?
If you accidentally damage your scleral lens, contact your eye care professional immediately. Do not attempt to repair the lens yourself.
How Often Should I Replace My Scleral Lenses?
The replacement schedule for scleral lenses varies depending on the material, your individual needs, and your eye care professional's recommendations. This is typically discussed during your fitting appointment.
This comprehensive guide offers a foundation for maintaining the cleanliness and hygiene of your scleral lenses. Always follow your eye doctor's specific instructions and contact them immediately if you experience any discomfort or problems. Remember, proper lens care is paramount for maintaining optimal eye health and vision.
