High-speed photography of excimer laser ablation of the cornea
- https://pubmed.ncbi.nlm.nih.gov/3632443/
- We have used laser-based high-speed photography to investigate excimer laser ablation of the cornea. Photographs of the ablation plume were obtained 500 ns to 150 microseconds after incidence of a 193- or 248-nm excimer laser pulse on the surface of the cornea. Ejection of material from the cornea begins on a time scale of nanoseconds and continues for 5 to 15 …

- Photographs of the ablation plume were obtained 500 ns to 150 μs after incidence of a 193- or 248-nm excimer laser pulse on the surface of the cornea. Ejection of material from the cornea begins on a time scale of nanoseconds and continues for 5 to 15 μs following the excimer pulse. At 193 nm the ablation plume resembles a burst of smoke, and individual particles are too …

- The excimer laser (Schwind Keratom) was calibrated according to the manufacturers' instructions. On freshly enucleated pig eyes, planokeratectomies with a diameter of 5 mm and a planned depth of 20, 40, 80, 160, and 320 microns were performed. With a newly developed high-precision, high-speed reflectometer the corneal thickness was measured immediately before …
Excimer laser ablation of the cornea and lens. Experimental
- https://pubmed.ncbi.nlm.nih.gov/4034169/
- Abstract. The pulsed ultraviolet excimer laser has been used to produce tissue ablation with a high degree of precision and with minimal thermal damage to adjacent structures. In comparative studies of excimer laser ablation of the cornea and crystalline lens using 193 nm and 248 nm radiation, threshold fluence for corneal and lens ablation was higher at 248 nm than at 193 nm.
Photography of shock waves during excimer laser ablation of the …

- Shadow photography of shock waves excited by means of a xenon chloride excimer laser was performed to determine the shock wave propagation velocity in air, nitrogen and helium. Energy densities between 500 and 2,000 mJ/cm2 were used to ablate a rotating rubber cylindrical target and porcine corneas.

- This laser can separate the structural bonds in the corneal tissue, accurately produce light cutting effect, remove the corneal tissue by vaporization, and then change the curvature of the corneal surface to achieve the purpose of refractive correction. Trokel adopted excimer laser in keratectomy in 1983.
