Vitreoretinal ablation with the 193-nm excimer laser in fluid media.
PURPOSE To ablate retina and vitreous membranes using the 193-nm argon fluoride excimer laser in a fluid medium. METHODS A special delivery system for the 193-nm excimer laser was developed that enabled the delivery of the laser into high-absorption liquid environments. The system was tested on the retina in an in vitro cup preparation of cow's eyes, and also in vivo on retina and vitreous me...
متن کاملCorneal surface ablation by 193 nm excimer laser and wound healing in rabbits.
The 193 nm argon fluoride excimer laser was used to ablate a 6 mm diameter area of the central rabbit cornea under various conditions of power, beam configuration and exposure time. High repetition rates or prolonged exposures produced charring and prevented rapid epithelial wound closure. Endothelial vacuolization, reduction in density, and displacement of cell material into Descemet's layer r...
متن کاملTechnique for cellular microsurgery using the 193-nm excimer laser.
A new cell surgery technique has been developed to produce well-defined alterations in cells and tissue without detectable heating and/or other structural damage in the surroundings. The technique involves the use of an argon fluoride excimer laser, in the deep ultraviolet (UV) region of the spectrum at 193 nm, which is guided through a glass pipette filled with a positive air pressure. To demo...
متن کاملHuman corneal ablation threshold using the 193-nm ArF excimer laser.
PURPOSE To determine the human corneal threshold ablation energy density for the 193-nm ArF excimer laser, approximating clinical conditions. METHODS The VISX Star (Santa Clara, CA) 193-nm argon fluoride excimer laser was used to ablate the cornea in human eye bank eyes under clinical conditions. Corneas were exposed to energy densities of 10, 20, 30, 35, 40, 45, and 140 to 160 mJ/cm2. Cornea...
متن کاملVitreoretinal surgery assisted by the 193-nm excimer laser.
PURPOSE Ablating and cutting vitreoretinal membranes using a 193-nm excimer laser-based microsurgical system. METHODS A 193-nm microsurgical system enables delivery of the beam into a fluid medium to cut preretinal and subretinal membranes. Two patients with proliferative diabetic retinopathy and one patient with proliferative vitreoretinopathy were treated with this new device. RESULTS Gen...
