What is it indicated for?
RESCAN 700 provides non-contact, high resolution, optical coherence tomographic (OCT) and biomicroscopic imaging of the anterior and posterior segment of the eye via an ophthalmic surgical microscope. The RESCAN 700 is indicated for in vivo viewing, axial cross sectional, and three-dimensional imaging of posterior ocular structures, including retina, macula, and optic disc, as well as imaging of anterior ocular structures, including the cornea, lens and anterior chamber angle.
RESCAN 700 uses the assistance system (CALLISTO eye) that provides non-diagnostic video documentation and image capture for ophthalmic surgeries. The assistance system allows the remote control of RESCAN 700.
Indications for use as stated in the FDA summary.
