Zusammenfassung:Studies concerning the optical phenomenology of the eye and refractive structures such as the cornea and lens among others, have qualitative and quantitative information from emmetropy and refractive error of this optical system in particular. In the developed work it was to determine the location of the principal planes in the cornea of 192 people treated at the clinic Santo Tomas University based Bucaramanga. He started taking information from the measures of the radii of curvature of the anterior, posterior surface of the cornea and corneal thickness generated by the Pentacam HR which were recorded in the archives of the School of Optometry in periods of 2009 to 2012. Physical and mathematical equations, text Physiological Optics Mariano Aguilar, are used and the main points and planes of corneal diopter are determined. It was possible to determine the power of the cornea with an average value of 41.07 D representing 3.05% error from the theoretical value of 42.36 D. It also was determined that in each of the age groups location the principal planes and was left out of the cornea, which is consistent with the dioptric optical physiology research. It can be said that the location of the principal planes in the cornea can be affected by patient age being analyzed. The results obtained make it possible correlations with the exercises and / or models made at national and international level in the field of optometry, ophthalmology, among others, complementing the knowledge we have about optical physiology of the cornea. Los estudios concernientes a la fenomenología óptica del ojo y sus estructuras refractivas como la córnea y el cristalino, entre otras, presentan información cualitativa y cuantitativa de las emetropías y ametropías de este sistema óptico en particular. En el trabajo desarrollado se propuso determinar la ubicación de los planos principales en la córnea de 192 personas atendidas en la clínica de la Universidad Santo Tomás sede Bucaramanga. Se inició tomando la información de las medidas de los radios de curvatura de la cara anterior, cara posterior de la córnea y el espesor corneal, generados por la Pentacam HR, los cuales fueron registrados en los archivos de la Facultad de Optometría en los periodos de 2009 a 2012. Se utilizan las ecuaciones fisicomatemáticas del texto de Óptica Fisiológica de Mariano Aguilar, y se determinan los puntos y planos principales del dioptrio corneal. Se logró determinar la potencia de la córnea con un valor prom
