yperopia

Farsightedness

With hyperopia, the cornea does not bend incoming light enough, so light focuses behind the retina.

Hyperopia causes blurry vision up close and at distance. Hyperopia must be distinguished from presbyopia, which is clear vision at distance with a need for reading glasses up close.

When LASIK is performed for hyperopia, the corneal surface is gently steepened by the laser, resulting in more bending of incoming light and proper focusing on the retina.
