[How to correct anisometropia?]

Anisometropia may be responsible for aniseikonia. and anisophoria. In children, aniseikonia may create amblyopia. It is of utmost importance to distinguish axial from refractive anisometropia. When the anisometropia is axial in origin, spectacle lenses constitute the treatment of choice (Knapp's law). On the contrary, when the anisometropia is refractive in origin, contact lenses represent the first choice of treatment.
