True about adult cornea:
D i.e. Microcornea - diameter less than 10 mm Horizontal diameter of cornea at bih is 10 mm and the adult size (11.7 mm) is attained by the age of 2 years. Megalocornea is labeled when the horizontal diameter of cornea is of adult size at bih or >13 mm after the age of two yearsQ. In microcornea horizontal diameter is < 10 mm since bihQ (or < 11mm in greatest dimension.
