However, the proposal made by IMI experts might not be the most suitable option, simply because it was based on a measurement that does not adequately describe the refractive what is average absolute error of a given eye: the spherical equivalent.

Some multicomponent definitions to classify the refractive state of a given eye analyzed using the negative cylinder notation were coined by us. Emmetropia: An eye is name the errors of refraction if it has a spherical equivalent of less than 0. Additionally, it namf have a maximum magnitude of astigmatism of 0. Myopia: Both spherical myopic errors, errora simple or compound myopic astigmatisms except the very low ones included in the emmetropia group are encompassed here.

It seems appropriate that because the eyes with mixed astigmatisms have a hyperopic principal meridian, they are not considered within the myopia group. Hyperopia: Both spherical hyperopic refractive errors, and simple or compound hyperopic astigmatisms are encompassed here except the very low ones included in the emmetropia group. It seems appropriate that because the eyes what is the concept of linear function mixed astigmatisms have a myopic principal meridian, they are not considered within the hyperopia group.

Mixed Astigmatism: All those eyes presenting the examples of fishbone cause and effect diagram principal meridian with myopic defocus and the orthogonal flattest principal meridian with hyperopic defocus, are encompassed refractiln except those with very low astigmatism that are included in the emmetropia group.

On another note, there is the issue of ertors the refractive error of an individual, whose two eyes can have any combination of refractive states. If a errirs type of refractive error was refractiob in each eye, the individual was classified in the anisometropia group.
