Objectives: To know the topographic patterns of the keratoconus in our environment by assessing the topographic indexes obtained from them. Methods: the universe of study was composed of 100 eyes from patients who had been diagnosed this disease. They underwent a corneal topography study where different variables, such as dioptric power in the apex of the cone and its axis, dioptric central power of the eye and of the adelphos eye, the difference between the upper and lower corneal dioptric power, and astigmatism, were analyzed. Results: it was found that the central asymmetric keratoconus is the predominant.The topographic values and the difference of the apex of the cone between both eyes were higher in the central and peripheral keratoconus. Likewise, astigmatism was elevated in these patterns, whereas the values of the apex of the cone and its axis, the central dioptric power of the eye, of the adelphos eye and the difference between the upper and lower corneal dioptric power were lower in the central keratoconus. As regards the axis, it was evidenced the predominance at the lower temporary level. Conclusions: In this setting, the keratoconus is a poorly studied pathology and this paper tries to establish the prevailing topographic patterns where 3 basic types were found: the central, the central asymmetric and the peripherical keratoconus with significant topographic values.
