Corneal thickness (A.), hydration (B.), hydroxypoline content (C.) and total amount of sulphated GAG (D.) across the bovine cornea as a function of position. 0–3 mm = centre, 3–6 mm = inner periphery, 6–9 mm = mid periphery, 9–12 mm outer periphery/limbus. One-way ANOVA and post-hoc Tukey HSD tests were employed to identify the significant differences between the groups. (*) p = ≤ 0.01. (**) p = ≤ 0.001.
