  2. 1. Manipulation of Ocular Aberrations in Myopes

    Author : Baskar Theagarayan; Jörgen Gustafsson; Frank Schaeffel; Linnéuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Myopia; Spherical aberration; Accommodation; Contact lens; Visual acuity; Peripheral aberrations; Optometry; Optometri; Optometry; Optometri;

    Abstract : Myopia is a major cause of vision loss throughout the world. High myopia is associated with severe eye diseases like maculopathy, retinal detachment and glaucoma. The prevalence of myopia is increasing, and varies by country and by ethnic group. In some Asian populations the prevalence is 70%-80%. READ MORE

  4. 2. Myopia control and peripheral vision

    Author : Petros Papadogiannis; Linda Lundström; Peter Unsbo; Nicola Logan; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; myopia; peripheral vision; psychophysics;

    Abstract : The rapid rise in myopia prevalence has caused an urgent need for effectivemyopia control interventions. This thesis investigates the role of theperipheral optics of the human eye in myopia progression. It was initiallybelieved that the axial elongation of the myopic eye is caused only by thedefocus signals presented to the central retina. READ MORE

  5. 3. Glaucoma Characteristics and Risk Factors - Results from Malmö Eye Survey

    Author : Kirsti Grødum; Oftalmologi (Malmö); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vascular disease; Ophtalmology; Oftalmologi; myopia; optic disc hemorrhages; mortality; refraction; glaucoma; population screening;

    Abstract : This thesis is based on data from a large glaucoma screening, comprising 32, 918 elderly citizens of Malmö and data from retrospective analysis of glaucoma patients’ charts from the Eye Department of Malmö University Hospital. The definition of glaucoma was based on reproducible visual field defects and/or glaucomatous optic nerve head damage in both groups. READ MORE

  6. 4. Transverse Chromatic Aberration and Vision: Quantification and Impact across the Visual Field

    Author : Simon Winter; Linda Lundström; Stephen Burns; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transverse chromatic aberration; lateral chromatic aberration; visual optics; peripheral vision; central vision; dispersion; ophthalmic optics and devices; optical effects on vision; retinal imaging; myopia; human eye; Fysik; Physics;

    Abstract : The eye is our window to the world. Human vision has therefore been extensively studied over the years. However, in-depth studies are often either limited to our central visual field, or, when extended to the periphery, only correct optical errors related to a narrow spectrum of light. READ MORE

  7. 5. Ocular aberrations and visual quality in aspherical and multifocal contact lenses

    Author : Anna Lindskoog Pettersson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Contact lenses;

    Abstract : Good visual quality and precise accommodation are required to be able to focus objects at distance and near, and are essential in order to be able to perform most tasks in life. Most eyes are not ideal eyes, i.e., they have different refractive errors which distort the produced image. READ MORE
