The use of remote optical feedback systems represents a promising approach for minimally invasive, nerve-sparing laser surgery. Autofluorescence properties can be exploited for a fast, robust identification of nervous tissue. With regard to the crucial step towards clinical application, the impact of laser ablation on optical properties in the vicinity of structures of the head and neck has not been investigated up to now. We acquired 24,298 autofluorescence spectra from 135 tissue samples (nine ex vivo tissue types from 15 bisected pig heads) both before and after ER:YAG laser ablation...

Glaucoma remains a prevalent disorder and visual limiting factor after Boston keratoprosthesis type 1 implantation. Patients with glaucoma have worse initial and late visual acuity outcomes after otherwise successful keratoprosthesis implantation. Management of glaucoma in the setting of a keratoprosthesis is challenging because of relatively rapid progression and an inability to accurately measure intraocular pressure (IOP). In addition, there are no standard guidelines for glaucoma surveillance and monitoring after keratoprosthesis surgery...

Extreme ultraviolet (EUV) spectra from laser produced bismuth plasmas were recorded in the 8-17 nm spectral region using a Nd:YAG laser with a pulse length of 8 ns operating at a range of laser power densities. Due to the broad-band emission at 8-17 nm, bismuth plasmas show promise as sources of quasicontinuous radiation in the extreme ultraviolet. When varying the incident laser power density, ionic populations of Bi ions at different power densities were estimated by the collisional-radiative (CR) model for explanation of changes in the spectral profile...
