Evaluation of cornea biomechanical properties is essential for different ophthalmological operations such as refractive surgeries and for accurate measurement of intraocular pressure (IOP). Changes in mechanical properties of cornea result in corneal diseases such as corneal ectasia as well as cornea refractive problems. Evaluation of corneal material properties can be used as a beneficial tool for recognizing these corneal diseases. Moreover, accurate estimation of IOP makes detection of pathological diseases like glaucoma more feasible. Thus, characterization of corneal biomechanics is key to help ophthalmologist and to come up with new techniques and innovative equipment for these diseases. There are currently four methodologies in characterization of biomechanics of cornea; mechanical tests (stress relaxation and creep test), optical coherence tomography (OCT), Shear Wave Elastography (SWE) and Tonometry tests (Corvis tonometry).
