FIG. 2.

Photograph of the eye coupling device used during in vivo New Zealand White rabbit experiments. The rabbit's eye was coupled to the system via the eye coupling device; the glass test tube was filled with phosphate-buffered saline solution to accomplish refractive index matching. The rabbits were placed in a custom-built rabbit holder to provide comfort and rabbit orientation, which allowed for repeatable positioning of the rabbit to achieve eye coupling.
