We are constantly impressed with the performance of our Pulzar Z1 Solid State Flying Spot Laser. It has a high ablation efficiency, working at 213 nm which is close to the peak absorption peak of the collagen in the corneal tissue. This produces minimal thermal effect, and is not influenced by variations in corneal hydration or humidity which is especially beneficial for TransEpithelial ablations. The uniform Gaussian beam and 300 400 Hz pulse rate produces a smooth ablation, which along with the 1 kHz closed loop tracker ensures a reliable outcome. The “PresBVis” Ablation Profile is particularly helpful for those needing a reading correction as well. Accurate Custom Ablations are also possible for tricky corrections.
