Mucin balls are primarily associated with which type of lenses?

Mucin balls are primarily associated with silicone lenses. The silicone material in these lenses interacts with tear film components, particularly mucin, which can lead to the formation of mucin balls. These are small, spherical aggregations of mucin that can accumulate between the lens and the cornea.

Silicone lenses are known for their high oxygen permeability, which makes them suitable for extended wear and provides comfort for many patients. However, their affinity to attract mucin can cause complications such as discomfort and variable vision, which is a concern for both practitioners and wearers.

The other types of lenses do not exhibit the same level of interaction with tear film components as silicone lenses do, leading to mucin ball formation being less prevalent with hydrophilic lenses, orthokeratology lenses, and extended wear lenses not made from silicone materials.
