       title = {A new nanosecond UV-laser at 355 nm: early results of corneal flap cutting in a rabbit model},
       journal = {Investigative Ophthalmology & Visual Science},
       abstract = {Purpose: A new 355nm UV laser was used for corneal flap cutting in an animal model and tested for clinical and morphological alterations. Methods: Corneal flaps were created (Chinchilla Bastards; n=25) with an UV-nanosecond laser at 355nm (150kHz, pulse duration 850ps, spot-size 1µm, spot-spacing 6x6µm, side-cut Δz 1µm; cutting depth 130µm) and pulse energies of 2.2 or 2.5µJ, respectively. Following slit lamp examination, animals were sacrificed at 6, 12 and 24hrs after treatment. Corneas were prepared for histology (HE, TUNEL-assay) and evaluated statistically, followed by ultrastructural investigations. Results: Laser treatment was tolerated well, flap lift was easier at 2.5µJ compared to 2.2µJ. Standard HE at 24hrs revealed intact epithelium in the horizontal cut, with similar increase in corneal thickness at both energies. Irrespective of energy levels, TUNEL assay revealed comparable numbers of apoptotic cells in the horizontal and vertical cut at 6/12/24hrs, becoming detectable in the horizontal cut as an acellular stromal band at 24hrs. Ultrastructural analysis revealed regular morphology in the epi- and endothelium, while in the stroma, disorganized collagen lamellae were detectable representing the horizontal cut, again irrespective of energy levels applied. Conclusions:This new UV-laser revealed no epithelial nor endothelial damage at energies feasible for corneal flap cutting. Observed corneal swelling was lower compared to existing UV-lasers-studies, albeit total energy applied here was much higher. Observed loss of stromal keratinocytes is comparable to available laser systems. Therefore, this new laser is suitable for refractive surgery, awaiting its test in a chronic environment.},

       abstract = {We determined the bubble radius R_(max) for femtosecond optical breakdown in water at 347, 520, and 1040 nm with an unprecedented accuracy (+/-10 nm). At threshold, R_(max) was smaller than the diffraction-limited focus radius and ranged from 190 nm to 320 nm. The increase of R_(max) with laser energy E_(L) is slowest at 347 nm, providing optimum control of cell surgery. Experimental results agree with a model of bubble formation in heated and thermoelastically stretched liquids. Theory predicts a threshold temperature T_(th) approximately equal to 168 degrees C. For T>300 degrees C, a phase explosion sets in, and R_(max) increases rapidly with E_(L).},
