3117 Contralateral corneal modification after 193 nm excimer and 213 nm UV solid state laser photoablations
PURPOSE: Ah the population of puticnts undergoing current rcfractivc procedures increases, il is now important for rliniciaos of all beckgmunds to know the various FDA and DHSS approved topical prcpantions which are roudnely used in the managemeot of tyes after Radial Kcretotomy (RK) sod IIxc:imer laser photorefractive kcratectomy (PRK). METIIODS: This paper prcsentn details of the various effe...
متن کاملPhotorefractive keratectomy using solid state laser 213 nm and excimer laser 193 nm: a randomized, contralateral, comparative, experimental study.
PURPOSE To compare histopathologic changes after photorefractive keratectomy (PRK) for myopia using either a solid state laser (SSL) at 213 nm or an excimer laser (EL) at 193 nm in an experimental model. METHODS Forty pigmented rabbits (80 eyes) underwent myopic PRK for the correction of 6 D. Photoablation was randomly assigned, with a solid state laser used in one eye and an EL in the fellow...
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 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...
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...
