Distribution of average corneal refractive power. The sample size was 296 patients’ right eyes. FS1-FS4 denote the mean corneal refractive power at the 4 mm, 6 mm, and 8 mm superior corneal locations. FI1-FI4 denote the mean corneal refractive power at the 4 mm, 6 mm, and 8 mm inferior corneal locations. FT1-FT4 represent the average corneal refractive powers at the 4, 6, and 8 mm positions on the temporal side of the cornea. FN1-FN4 represent the average corneal refractive power at the 4, 6, and 8 mm positions on the nasal side of the cornea.
