Nevertheless, there are differences in the patterns of visual loss among the clinically defined categories, particularly between strabismic and anisometropic categories. (nyu.edu)
Clinically1
Patients may have up to 3D of anisometropia before the condition becomes clinically significant due to headache, eye strain, double vision or photophobia. (wikipedia.org)
Patients1
Using a non-linear aspheric ablation profile, PRESBYOND induces a small anisometropia of up to -1.5 D. PRESBYOND also controls the amount of spherical aberration in order to achieve an amount within the so-called "therapeutic" range that gives patients increased depth of focus, allowing for continuous focused vision over a range of distances.

Eyes7
Anisometropia is a condition in which a person's eyes have substantially differing refractive power. (wikipedia.org)
In certain types of anisometropia, the visual cortex of the brain cannot process images from both eyes simultaneously (binocular summation), but will instead suppress the central vision of one of the eyes. (wikipedia.org)
For those with large degrees of anisometropia, the wearing of standard spectacles may cause the person to experience a difference in image magnification between the two eyes (aniseikonia) which could also prevent the development of good binocular vision. (wikipedia.org)
[ 5 ] Anisometropia exists when a refractive difference between the 2 eyes of 1.25 diopters of sphere or 1 diopter of cylinder is present. (medscape.com)
However, anisometropia refers to cases where the refractive error is different in both eyes (by 1 or more dioptres ). (londonvisionclinic.com)
Orthotropia is defined as the correct direction of the eyes under binocular conditions. (nih.gov)
Based on the age of onset of strabismus, it can be defined as infantile, when the deviation of eyes has been noticed at or before 6 months of age. (nih.gov)
Mild1
Anisometropia causes some people to have mild vision problems, or occasionally more serious symptoms like alternating vision or frequent squinting. (wikipedia.org)
Decrease1
However, anisometropia is associated with age regardless of cataract development: a rapid decrease in anisometropia during the first years of life, an increase during the transition to adulthood, relatively unchanging levels during adulthood but significant increases in older age. (wikipedia.org)

Disposable," as defined by the FDA, means used once and discarded. (mastereyememphis.com)

Some studies suggest, in older adults, developing asymmetric cataracts may cause worsen anisometropia. (wikipedia.org)
Acuity1
The distance between the person's eyes and the testing chart is set so as to approximate " optical infinity " in the way the lens attempts to focus (far acuity), or at a defined reading distance (near acuity). (explained.today)
