The Antibacterial Efficacy of High-Fluence PACK Cross-Linking Can Be Accelerated
Febbraio 28, 2023
The article by Lu et al. reports an in vitro study, conducted to determine whether high-fluence PACK-CXL can be accelerated while still maintaining its antibacterial efficacy. The study found that high-fluence PACK-CXL did indeed decrease the bacterial concentration of several clinically significant bacterial strains, including S. aureus, P. aeruginosa, and S. epidermidis. These strains are commonly implicated in bacterial keratitis and contact lens-associated keratitis. Furthermore, the authors found that higher total fluence PACK-CXL protocols led to a corresponding increase in bacterial killing ratio (BKR).
