Laser doppler vibrometry for eye surface vibration measurement to determine cell damage

Technologies are described for detection of eye surface vibrations to determine cell damage within a treatment area of an eye undergoing laser treatment. Eye surface vibrations may be caused by intraocular pressure waves that form during the laser treatment. For example, the pressure waves may originate from a plurality of bubbles forming and/or rupturing inside cells located in the treatment area. The bubbles may form as energy from a treatment laser beam is absorbed by the retinal tissue. The pressure waves may be measured at the surface of the eye through Doppler vibrometry to determine if the cells within the treatment area have been damaged. The damage to the cells may include cell lysis, a rupture of cell membranes, scarring, and/or photocoagulation, among other examples.
