Eleven commandments for teaching ophthalmic surgery. ![]() When using animal ex vivo models such as porcine corneas for experimental corneal surgery, findings such as these should be considered.ĭreyer EB, Volpe NJ. The topography and pachymetry of the porcine cornea showed a specific configuration differing from the human cornea. The BFSs were 38.14 ± 0.73 D (anterior) and 42.56 ± 1.15 D (posterior), and the mean refractive powers were 43.27 ± 1.08 D (anterior) and -5.15 ± 0.20 D (posterior) therefore, the mean of the total refractive power was 38.16 ± 1.00 D. The mean WTW diameter was 13.81 ± 0.83 mm, and the mean corneal thickness was 832.6 ± 40.18 µm. The mean keratometric powers were 39.6 ± 0.89 D (K1) and 38.5 ± 0.92 D (K2), and the mean astigmatism was 1.1 ± 0.78 D. We assessed the steepest and flattest keratometric powers (K1 and K2, units in diopters (D)), astigmatism (D), white-to-white (WTW) diameter (mm), thinnest point pachymetry (µm), anterior and posterior best-fit sphere (BFS) (D), refractive power of the anterior and posterior curvatures, and total refractive power of the cornea (D). We evaluated freshly enucleated porcine eyes (n = 16) by performing computerized corneal topographies (Orbscan® IIz, Bausch and Lomb, Rochester, NY, USA). This study investigated the corneal topography and pachymetry of the porcine eye to provide further reproducible data. It is well suited for investigations concerning refractive surgery however, corneal topography data are scarce. The porcine eye is often used as an ex vivo animal model in ophthalmological research. ![]()
