Abstract

The cornea is the outermost surface of the eyeball; and has almost 70% of the eyes total refractive power, what makes it essential for the human vision process. However, some pathologies and refractive errors modify normal functions of the cornea, decreasing visual acuity along with the individual's quality of life. Thus, in the presence of ametropia, an appropriate diagnosis, treatment, and corrections of cornea's dimensions is vital. Nowadays, several methods to retrieve corneal topography are available. In this paper, the most relevant techniques in the field are presented.
