Synonyms hypermetropia long-sightedness(EYES)mainly UK Opposite myopia See also presbyopia The procedure reshapes the corneal tissue to correct astigmatism, hyperopia, and myopia. Hyperopia is corrected by steepening the cornea, allowing light rays a longer path so that they focus at the correct spot on the retina.

At high concentrations, it also prevented hyperopia development. No effect of the glucagon antagonist on hyperopia development was visible at the lower and the higher dose. In contrast, the brother remains hyperopia and has exhibited no specific retinal findings until age 18 years. The glucagon antagonist inhibited hyperopia development, albeit only in a narrow concentration range, and at most by 50%, but not myopia development. For instance, two boys had mild or low hyperopia, one had myopia, and one had a relatively important astigmatism.
