Abstract

Laser ablation of tissue can be accompanied by deleterious straining. A polaroscopic technique was used to image induced strain. In a bovine cornea model, we demonstrate that strain induced by a cavitation bubble occurs over an area larger than the bubble. Further, although the bubble lifetime is only about 400 μs and the cornea tissue is strained greatly by the expanding and collapsing bubble, there is substantial strain for several milliseconds after the bubble collapse. The results indicate the utility of polaroscopic imaging as well as the magnitude and spatial extent of mechanical events at times long after the initiating mechanical insult.
