System and method of obtaining biomechanical parameters of ocular tissue through deformation of the ocular tissue
Application Number: EP20382067
Date of receipt: 02 February 2020/ Madrid, Spain.
The invention relates to a system for obtaining biomechanical parameters of ocular tissue (C), the system comprising:- an air-puff module (200) configured to deliver at least one air-puff stimulus onto the ocular tissue;- an imaging device (100, 100') operatively coupled to the air-puff module (200); characterised in that- the air-puff module comprises a transparent window (PW) at its front thereof, the transparent window having a hole (OD) for delivering the at least one air-puff stimulus, the hole configured to be aligned with an optical axis of the imaging device, such that the air-puff stimulus delivered onto the ocular tissue can be centred on an apex of the ocular tissue and can be made collinear with the optical axis of the imaging device;- the imaging device (100, 100') being configured to capture a plurality of points distributed throughout a surface of the ocular tissue;the system further comprising:- processing means configured to process the plurality of points provided by the imaging device for obtaining biomechanical parameters of the ocular tissue.The invention also relates to a method for obtaining biomechanical parameters of ocular tissue, especially, corneal biomechanical parameters.
