Air-puff induced corneal deformation imaging reveals information highlighting normal and pathological corneal response to a non-contact mechanical excitation. Here, we present a novel customized swept-source optical coherence tomography system coupled with a collinear air-puff excitation. We acquired unobstructed dynamic corneal deformation on multiple meridians with two custom scan patterns over a field of view of up to 15 mm x 15 mm and selected puff profiles at unprecedented scan rates, both ex vivo and in vivo. We show that our system can detect corneal deformation profiles and deformation asymmetries that are useful for corneal biomechanics diagnostics and pathology screening.
