Miniature fiber-optic force sensor for vitreoretinal microsurgery based on low-coherence Fabry-Pérot interferometry.


Vitreoretinal surgery requires delicate manipulation of retinal tissue. However, tool-to-tissue interaction forces in the order of sub-millinewton are usually below the human sensory threshold. A surgical force sensor (FS) compatible with conventional surgical tools may significantly improve the surgery outcome by preventing tissue damage. We have designed… (More)
