Abstract
This work seeks to determine the modulus of elasticity of the cornea from corneal biomechanical parameters. Data was taken from the ophthalmological exams of 55 patients. All these patients have undergone some type of surgery or treatment. Of these patients, 70.37% are considered to have a healthy corneal structure and 24.07% have pathological corneas according to the biomechanical properties of the corneal structure. The calculation is performed and the results of the corneal elasticity module are presented for both healthy and pathological corneas before and after having over-come the disease after the surgical intervention. The tabulated results are truly important within the ophthalmological field because they serve as a tool to know the structural state of the corneal tissue of each patient. With this modeling it is intended that it is possible to diagnose eye diseases promptly and thus prevent difficulties in the patient’s vision.
