Corneal topographic changes according to chalazia size. Chalazia are classified into control, small-, medium- or large-sized groups. Astigmatism by simulated keratometry (simK; a), second order aberration (b), oblique astigmatism (Z-2 2; c), and vertical astigmatism (Z2 2; d) are significantly greater in the large-sized chalazion group (p = 0.037, 0.036, 0.006, and 0.002, respectively; one-way analysis of variance)
