long-sightedness
A combination of myopia and hypermetropia is known as mixed astigmatism.
Occasionally, correction of hypermetropia with glasses is sufficient to straighten the eye.
In cataract surgery the natural lens of the eye is removed, which leads to a significant decrease in the optical convergence power of the eye or hypermetropia.
