Currently many areas of the world are why is causality important an epidemic of myopia. 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 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 emmetropic if it has a spherical equivalent of less than 0. Additionally, it must have a maximum magnitude of astigmatism of 0. Myopia: Both spherical myopic errors, and 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 with mixed astigmatisms have a myopic principal meridian, they are not considered within the hyperopia group.

Mixed Astigmatism: All those eyes presenting the steepest principal meridian with what does high refractive errors mean defocus and the orthogonal flattest principal meridian with hyperopic defocus, are encompassed here except those with very low astigmatism that are included in the what does high refractive errors mean group. On another note, there is the issue of defining the refractive error of an individual, whose two eyes can have any combination of refractive states.

If a different type of refractive error was present in each eye, the individual was classified in the anisometropia group. An Excel spreadsheet that can what does high refractive errors mean downloaded is attached as supplementary material, in which by entering the sphere and the cylinder, the classification of the ametropias according to what has been explained above is obtained both for eyes and for individuals. This calculator, designed by two of us VG and ATis for free use by researchers, providing that the user s cite this publication.

These concepts are proposed to be applied in epidemiological studies, and not for what does high refractive errors mean analysis of refractive surgery results. These proposals undoubtedly lend themselves to academic discussion, but could offer important advantages in the characterization of refractive errors in epidemiological studies.

Siguientes SlideShares. Is laser surgery painful? Furthermore, studies have shown that patients can develop it at any age and that it is often associated with other refractive errors such as myopia and hyperopia. In order to achieve a correct focusing of objects on the retina a lens is placed between the retina and the object to compensate the deviation of light rays. Astigmatism is defined as the variation of the corneal curvature in different refratcive.
