The ability to perform multi-meridian, simultaneous OCT measurements of air-induced corneal deformation is expected to highly improve the accuracy of assessing corneal biomechanics. We propose a simplified method targeting 3-D deformation measurement that could be introduced to swept-source OCT systems. We utilize a spatial-depth-encoded multiplexing to provide a 9-spot measurement of the deformation. The method is promising for the assessment of corneal asymmetries and diagnosis of corneal pathologies such as keratoconus. We present in detail the system and key requirements to provide simultaneous 9-spot deformation measurement. Finally, results on porcine eyes ex vivo and human eye in vivo are presented.
