Abstract: An ophthalmic surgical system includes a biomechanical imaging device configured to perform measurements of an eye of a patient. The system further includes a controller configured to: receive Brillouin light scattering (BLS) data from the BLS imaging device; calculate material properties according to the BLS data; select a tissue type according to the material properties; and generating an output corresponding to the tissue type. The biomechanical imaging device may include a confocal Brillouin microscope or a BLS spectrometer and a light source coupled to a fiber optic probe. Tissue types may include a retinal membrane, type of retinal membrane, or membrane-free area of the retina.

Abstract: A system includes an ophthalmic microscope configured to capture video of an ophthalmic treatment. A computer system is coupled to the ophthalmic microscope and is configured to: receive a first image from the ophthalmic microscope for a first wavelength band having a first width of less than 20 nanometers; receive a second image from the ophthalmic microscope for a second wavelength band having a second width of less than 20 nanometers; generate a vessel map of a retina of the eye of the patient according to the first image and the second image, the vessel map including representations of blood vessels of the retina; and display the vessel map on a display device. The computer system may further receive a reference image for an isosbestic wavelength band of oxygenated and de-oxygenated hemoglobin and generate the vessel map according to the reference image.
