• While emmetropia implies an absence of myopia, hyperopia, and other optical aberrations such as astigmatism, a less strict definition requires the spherical equivalent to be between -0.5 and +0.5 D and low enough aberrations such that 20/20 vision is achieved without correction. (wikipedia.org)

  • A sibling pair had unilateral high myopia in their right eyes and near emmetropia in their left eyes from infancy. (nih.gov)
  • Refraction was defined at baseline as follows: myopia as spherical equivalent of -1.00 diopters (D) or less, emmetropia as -0.75 to +0.75 D, and hyperopia as +1.00 D or more. (nih.gov)
  • However, individuals with myopia who had refractive surgery enjoyed the same vision-related quality of life as those with emmetropia. (visiontexas.com)
  • All the different vision conditions that cause us the need to wear glasses and contacts, which include: Myopia, hyperopia, and astigmatism are all considered "abnormalities" of emmetropia. (visiontexas.com)
  • In addition to understanding neural differentiation in the inner retina, so indispensable to retinal function, these studies have a direct bearing on gaining insight into the molecular basis of Emmetropia (In-focus vision) and its dysfunction, Myopia (short sightedness). (uclahealth.org)
  • From a large dataset containing biometric measurements (IOLMaster 700) of both eyes of 9734 patients prior to cataract surgery, eyes were indexed randomly as primary (P) and secondary (S). Intraocular lens power (IOLP) was derived for the HofferQ, Haigis and Castrop formulae for emmetropia for P and emmetropia or myopia (−0.5 to −2 dpt) for S to simulate monovision. (open.ac.uk)
  • If a person has emmetropic eyes, light rays entering the eye from a distance are directly focused on the retina, resulting in normal vision (emmetropia), otherwise, they will have ametropia. (visioncenter.org)
  • A possible solution to the third problem is to implant 2 (or more) IOLs simultaneously: one IOL with the predicted adult emmetropic power placed posteriorly and the other (or others) with the power that provides childhood emmetropia placed anterior to the first lens. (aao.org)

  • The state of 'zero error' is called emmetropia, so the process of eyes growing towards this state is called emmetropisation. (herts.ac.uk)
