Using Preservative Free Filling Solutions: Scleral Lens Care

Filling a scleral lens with preservative-free solution is crucial for several reasons, especially considering the sensitive nature of the eye and its susceptibility to irritation. Firstly, preservatives present in some solutions can cause adverse reactions or discomfort for individuals with sensitive eyes or those prone to allergies. Preservative-free solutions minimize the risk of irritation, ensuring greater comfort and reducing the likelihood of complications.
 

Scleral lenses cover a larger portion of the eye compared to traditional contact lenses.  This creates a reservoir of fluid between the lens and the cornea. This fluid helps maintain corneal health and provides lubrication, particularly for individuals with dry eyes or certain eye conditions. Using preservative-free solution ensures that this fluid is free from potentially harmful chemicals, promoting optimal ocular health and comfort.
 

Additionally, preservatives in some solutions can interact with the material of the scleral lens itself, leading to degradation or changes in lens properties over time. By using preservative-free solutions, the integrity and longevity of the lens are preserved, ensuring consistent performance and vision correction.
 

Overall, filling a scleral lens with preservative-free solution is essential for maintaining ocular health, maximizing comfort, and prolonging the life of the lens. It's a small but crucial step in ensuring a positive experience for individuals who rely on scleral lenses for vision correction.
