Abstract
Recently, we studied argon fluoride (ArF) excimer laser pulse propagalion in bovine cornea and aqueous collagen gels.5 Our results indicated that an ablative laser pulse induced a substantial transient decrease in target transmission, beginning during the 10 ns irradiation. Conversely, similar experiments performed on dehydrated films of extracted collagen exhibited a significant transmission increase during ablation. Therefore, we concluded that 193 nm laser ablation of cornea causes rapid changes in the tissue optical properties, which involve the water component.
