Fig. 1From: Effects of chalazia on corneal astigmatismCorneal topographic data for the chalazion and control groups. Simulated K (simK; (a) and astigmatism by simK (b) is similar between the two groups. Oblique astigmatism (Z−2 2; c) is greater in the chalazion group compared with the control group (p = 0.013; independent t-test)Back to article page
