In order to optimize dosimetry, the temperature at which maximal shrinkage of collagen fibrils occurs is of major interest. Since the exposure time in clinical LTK-treatment is limited to a few seconds, the kinetics of collagen denaturation as a rate process has to be considered, thus the time of exposure is of critical importance for threshold and shrinkage temperatures. We investigated the time-temperature correlation for corneal collagen denaturation within different time domains by turbidimetry of scattered HeNe laser probe light using a temperature controlled water bath and pulsed IR laser irradiation. In the temperature range of 60 degree(s)C to 95 degree(s)C we found an exponential relation between the denaturation time and temperature. For the typical LTK-treatment time of 2 s, a temperature of 95 degree(s)C is needed to induce thermal damage. Use of pulsed Holmium laser radiation gave significant scattering of HeNe laser probe light at calculated temperatures of around 100 degree(s)DC. Rate parameters according to the formalism of Arrhenius were fitted to these results. Force measurements showed the simultaneous onset of light scattering and collagen shrinkage.}, url = {http://dx.doi.org/10.1117/12.239611}, type = {Conference Proceedings}, Year ={ 1996} } |

To assess the potentials of photodisruption with picosecond pulses in comparison to the clinical techniques presently used, the shock wave characteristics and the bubble expension after optical breakdown with picosecond and nanosecond laser pulses were investigated by time resolved photography and acoustic measurements. Nd:YAG laser pulses with a wavelength of 1064 nm and a duration of 30 ps and 6 ns were focused into a water-filled glass cuvette. Their breakdown thresholds were 15 (mu) J and 200 (mu) J, respectively. Frequency doubled light from the same laser pulses was optically delayed between 2 ns and 136 ns and used as illumination source for photography. Since the individual events were well reproducible, the shock wave position and bubble wall position could be determined as a function of time. From the slope of these r(t) curves, the shock wave and bubble wall velocities were determined. The shock wave pressure p(r) was calculated from the shock velocity using the `jump conditions' of the shock front and the equation of state of water. The collateral effects of intraocular microsurgery can thus be considerably reduced by using ps-pulses, and with series of ps-pulses a `laser scalpel' may be realized which offers new applications of photodisruption.}, url = {http://dx.doi.org/10.1117/12.147544}, type = {Conference Proceedings}, year = { 1993} } |
