Ablation occurred consistently only 130 microns from the surface of the sclera. Using the same laser parameters as in Figure 5, Figure 6 shows a typical successful back surface ablation in the sclera using Hypaque. The cross sectional view clearly shows that no damage resulted before breakdown was achieved. Figure 4 . Transscleral photoablation using 1700 nm.
All craters are ablation sites.
Samples were about 0.6 mm thick. Depth penetration in untreated sclera. At further distances in, ablation occurred randomly as indicated by the occasional dark spot. Before SEM preparation, sample was 0.67 mm thick. Transscleral photodisruption using dehydration to induce transparency.
