Hypermetropia
Updates to Article Attributes
Hypermetropia, also known as long sightedness or hyperopia, is a refractive disorder. Whilst it can happen at any age group, it normally starts from mid-late adulthood.
In this condition, distant objects are seen better than objects which are close. There would be a degree of blurriness with the near objects due to incoming light being focused posterior to the retina. Common causes include a short ocular globe axial length, insufficient lens accommodation or flattened cornea.
Risk factors
familial condition
ocular tumours
presbyopia
Complications
if younger onset and untreated, can result in squint development
Treatment
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
-
non laser procedures
conductive keratoplasty
