Analysis of corneal data obtained from a Placido disk corneal topographer with calculation of irregularity indices. A corneal topographer is an ophthalmic clinical device that obtains measurements in the cornea (the anterior part of the eye). A Placido disk corneal topographer makes use of the Placido disk (Rowsey et al. (1981), <doi:10.1001/archopht.1981.03930011093022>, Rand et al. (1997), <doi:10.1016/S0886-3350(99)00355-7>), which produce a circular pattern of measurement nodes. The raw information measured by such a topographer is used by practitioners to analyze curvatures, to study optical aberrations, or to diagnose specific conditions of the eye. The rPACI package allows the calculation of the corneal irregularity indices described in Castro-Luna et al. (2020), <doi:10.1016/j.clae.2019.12.006>; Ramos-Lopez et al. (2013), <doi:10.1097/OPX.0b013e3182843f2a>; and Ramos-Lopez et al. (2011), <doi:10.1097/OPX.0b013e3182843f2a>. It provides a simple interface to read corneal topography data files as exported by a typical Placido disk topographer, to compute the irregularity indices mentioned before, and to display summary plots that are easy to interpret for a clinician.
