In search of more effective methods in the diagnosis vision and reduce the risk of post-operative ectasia, this article considers the importance of the biomechanical properties of the cornea and its close relationship with the development of corneal and possible conditions diseases in the human eye. For that reason, part of the literature is the review and analysis of the methods raised to remove accurate information from medical equipment, especially in the equipment Oculus Corvis and ORA from the Clinic “Santa Lucia” in the city of Quito. The corneal indices derived from these instruments can measure biomechanical parameters, but that is not accurate because of features such as geometry or thickness of the central corneal. The Young’s modulus corresponds to the elasticity of the corneal tissue. In addition, it is an important biomechanical feature that states different solutions for their extraction in vitro or in vivo through the use of numerical methods and/or modeling of complex systems of equations to simulate the real corneal tissue. There is also the obtaining of the elasticity of the cornea through processes of images of the human eye, which shows the action of the cornea at the time of using the tonometer. As a result, it demonstrate, in some cases, that the Young’s modulus relates only to the intraocular pressure, but also in other cases, it changes due to the increase of other factors such as age of people, corneal resistance, the central cornea thickness, etc.
