TRIAL DESCRIPTION
Public title Lasik and Anisometropia
Official scientific title The role of lasik in Anisometropia
Brief summary describing the background and objectives of the trial Anisometropia is marked inequality in the refraction of the two eyes a difference of more than two diopters. In certain types of anisometropia, the visual cortex of the brain will not use both eyes together (binocular vision) , and will instead suppress the central vision of one of them.
