Purpose: In recent years, there has been an increasing interest in eye washing in healthy individuals due to pollinosis and an increase in the number of people wearing contact lenses.

However, currently, a reduction in corneal epithelium disorders is assumed to be due to the popularization of eyewash solutions lacking BAK (over-the counter drugs).
Methods: We performed a comparative study between current eyewash solutions and those utilized in the past, and examined the effects of BAK on the cornea in both rabbit and human eyes.
Results: Eyewash solutions containing BAK were associated with corneal epithelium disorders and collapse of the mucin layer in the cornea. How.. View More»
