Abstract

Nowadays, the Shack-Hartmann aberrometer is one of the most widely used devices for measuring optical aberrations of the human eye due to the closed-loop automation features of this sensor. These aberrometers are used in fundus cameras to measure aberrations inherent to the human eye, which represent a deformation of the cornea that prevents the capture of eye images of high spatial resolution and can be compensated by adaptive optical systems. This article shows the validation of an experimental Shack-Hartmann aberrometer, which in the future will be used as the optimized adaptive optics arm of an eye fundus camera for the purpose of obtaining sharp images of the retina and its photoreceptors for the preventive diagnosis of anomalies that could generate partial or total loss of vision of the human being. The validation is done by a statistical analysis between the aberrations obtained from our experimental system and a commercial aberrometer. This analysis will be based on the most common aberrations of the human eye, e.g. myopia and astigmatism.
