Excimer laser photoablation of silicon
The ultraviolet and visible emission spectra from excimer laser-produced silicon plasmas were studied and the ablation rate measured as a function of laser energy density and wavelength. A spectroscopic investigation of the laser-produced plasma showed Si I, Si II, and Si III spectral lines with higher laser intensity causing a higher degree of ionization in the plasma. Both timeintegrated and ...
متن کاملEffect of Thermal Preconditioning Before Excimer Laser Photoablation
The purposes of this study were to assess the expression patterns of heat shock proteins (Hsps), after eyeball heating or cooling, and to elucidate their relationships with corneal wound healing and intraocular complications after excimer laser treatment. Experimental mice were grouped into three according to local pretreatment type: heating, cooling, and control groups. The preconditioning was...
متن کاملHSP47 expression in cornea after excimer laser photoablation.
PURPOSE The expression of heat shock protein 47 (HSP47) was observed histologically to investigate the spatial and chronological effects of excimer laser photoablation. HSP47 expression after radial keratotomy (RK) was also investigated and compared with the effects after excimer laser photoablation. METHOD Twenty-eight male rabbits were used. The rabbits were divided with two groups and trea...
متن کاملClinical photoablation with a 500-Hz scanning spot excimer laser.
PURPOSE The aim of this study was to use a 500-Hz scanning spot laser (Concept500, WaveLight Laser Technologie AG, Erlangen, Germany) to investigate potential side effects that might be associated with the use of a high repetition rate laser platform. METHODS Seven eyes were treated using a 500-Hz scanning spot laser for laser in situ keratomileusis (LASIK). The local frequency of the ablatio...
متن کاملEnhancement outcomes after photorefractive keratectomy and laser in situ keratomileusis using topographically guided excimer laser photoablation.
PURPOSE To evaluate the efficacy and safety of topographically guided excimer laser photoablation to retreat unsuccessful myopic and hyperopic photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK). SETTING Eye Clinic, San Salvatore Hospital, University of L'Aquila, L'Aquila, Italy. METHODS At least 3 months after primary PRK (Group A) or primary LASIK (Group B), 48 eyes...
