Preliminary study of argon fluoride (193 nm) excimer laser trabeculectomy Scanning electron microscopy at five months

Abstract

There is an increasing interest in the use of the excimer laser in ophthalmology, particularly in refractive surgery. The argon fluoride (193 nm) excimer laser ablates tissue with a high degree of precision and without any mechanical or thermal damage to surrounding structures. In this study, the argon fluoride excimer laser was experimentally used in the rabbit model to perform a trabeculectomy. Clinical and scanning electron microscopic evaluations showed a successful and patent filtering procedure. At the five-month follow-up the trabeculectomy was smooth and regular and there was no evidence of inflammation or thermal damage on the surrounding structures.
