Anisometropia and aniseikonia are easy to confuse and they often occur together. Both are possible complications of refractive surgery, but can occur naturally. Anisometropia is commonly stated to be present if the difference in the refractive correction is 2.00D or more either spherical or astigmatic. However, smaller differences than 2.00D may be significant. Anisometropia Clinical Trials and other clinical trials allow for volunteers to have healthcare treatment choices before they are available to the general public. Many times the subjects recieve treatment for without cost, and occasionally they are compensated for their time.

Anisometropia is a serious concern in newborns and young children because it can lead to amblyopia (impaired vision in one eye). With a major degree of anisometropia, the brain cannot able to reconcile the difference in images coming from the two eyes. Anisometropia of the spherical equivalent (ASFE) type increased in 27, and remained unchanged in 67 cyclopentolate. Fogging technique was used to ensure that patients did not have excessive minus power.

Patients who had completed therapy 1 or more years ago (N = 4) maintained their acuity improvement. From these results we conclude that following a sequential management plan for treatment of anisometropic amblyopia can yield substantial long-lasting improvement in visual acuity and binocular function for patients of any age.

Patients can cope with anisometropia up to 4.00 DS in some cases and have problems with 0.50DS in other cases(particularly where it has been surgically induced). If they are not presbyopic it would be worth having a go but warning the patient of adaptation problems and if they are struggling after a couple of weeks of trying, reducing the left prescription. Patients should address specific medical concerns with their physicians.

Patients with manifest strabismus usually cannot recognize the random-dot-stereographs of the test. However, any isometropic ametropia will hardly be detected by the test.

Anisometropia exists when there is a difference in the refraction between the two eyes. The eye with less refractive error provides the brain with a clearer image, and is favoured by the brain. Anisometropia is not correctable with a contact lens because of the patient's age and inherent lack of dexterity. The eye is otherwise quiet with no further complications. Anisometropia decreased uniformly to less than 2.00 D in all patients (mean 1.52 D). The percentage of patients with stereo acuity increased from 63.0 postoperatively.
