Microcornea is an abnormality of the size of the cornea of the eye, in which the cornea is smaller than 1cm (10mm) in diameter.

Some dictionaries define microcornea less specifically, as simply "abnormal smallness of the cornea" or "an abnormally thin and flat cornea".

There are several classifications of microcornea, including:

  • True microcornea - in which the eyeball itself has approximately normal dimensions and proportions.
  • Sclerocornea - in which the white "scleralization" of the edge of the cornea causes the cornea to appear smaller.
  • Microphtalmos - in which the cornea is small and its curvature may be abnormal.
  • Nanophthalmos - in which the person may have "long-sight" (hypermetropia) due to the short axial length of the eye/s.
