Corneal topographic changes according to the chalazion location. Chalazia are classified into control, nasal, middle, temporal, or whole area group. Astigmatism by auto-refractokeratometer (a), oblique astigmatism (Z−2 2; b), defocus (Z0 2; c), and secondary oblique astigmatism (Z−2 4; d) are significantly different between groups (p = 0.046, 0.033, 0.003, and 0.015, respectively, one-way analysis of variance)
