Hypermetropia

Last revised by Satish Kumar Gupta on 16 Sep 2023

Hypermetropia, also known as long-sightedness or hyperopia, is a refractive disorder. Though it can happen in any age group, it usually starts from mid-late adulthood.

In this condition, distant objects are seen better than close objects.

The blurriness of near objects is due to incoming light being focused posterior to the retina. Common causes include:

  • short ocular globe axial length

  • insufficient lens accommodation

  • flattened cornea

  • familial history

  • diabetes

  • ocular tumors

  • presbyopia

  • corrective lenses: convex

  • laser procedures

    • photorefractive keratectomy (PRK)

    • laser-assisted in situ keratomileusis (LASIK)

    • laser epithelial keratomileusis (LASEK)

    • laser thermal keratoplasty (LTK)

  • intraocular lens replacement

  • conductive keratoplasty

If younger onset and untreated, it can result in the development of a squint.
