The aim of this study was to assess the impact of refractive correction [spectacles vs rigid gas-permeable contact lenses (RGP CLs)] on the vision-related quality of life (VR-QoL) obtained with the standardized questionnaire, NEI-VFQ-25, in keratoconus patients compared with healthy myopic subjects. The Spanish version of NEI-VFQ-25 was administered two(More)
Amblyopia detection is important to ensure proper visual development and avoid permanent decrease of visual acuity. This condition does not produce symptoms, so it is difficult to diagnose if a vision problem actually exists. However, because amblyopia treatment is limited by age, early diagnosis is of paramount relevance. Traditional vision screening(More)
PURPOSE To compare the anterior corneal measurements between Placido-based topography and dual-Scheimpflug topography in healthy and keratoconus eyes. SETTING Optometry Research Group, Instituto Universitario de Oftalmobiología Aplicada, University of Valladolid, Valladolid, Spain. DESIGN Comparative case series. METHODS The mean simulated keratometry(More)
PURPOSE To determine and compare the repeatability of a Placido-based corneal topography (Oculus Keratograph) in a sample of healthy and keratoconus eyes. METHODS The corneal topography, determined using the Oculus Keratograph, of 25 healthy and 25 keratoconus eyes was assessed three consecutive times. A single randomized eye was included per patient.(More)
PURPOSE To determine and compare the repeatability of anterior corneal higher order aberrations (HOAs) using a Placido-based topographer (Allegro Topolyzer; WaveLight Technologie AG, Alcon Laboratories, Erlangen, Germany) in a sample of normal and keratoconic eyes. METHODS Three repeated measurements of each cornea of normal and keratoconic eyes were(More)
PURPOSE To determine the repeatability of the back optic zone radius (BOZR) of rigid gas permeable (GP) contact lens (CL) proposed by new software for fitting in healthy and keratoconus eyes and to compare with the diagnostic CL fitting method. METHODS Three consecutive corneal topographies (Oculus-Keratograph) were performed and analyzed with APEX new(More)
PURPOSE To calculate and validate a new web-based algorithm for selecting the back optic zone radius (BOZR) of spherical gas permeable (GP) lens in keratoconus eyes. METHODS A retrospective calculation (n=35; multiple regression analysis) and a posterior prospective validation (new sample of 50 keratoconus eyes) of a new algorithm to select the BOZR of(More)
OBJECTIVES To assess the percentage of successful rigid gas permeable (GP) contact lenses (CLs) fit for both refractive and therapeutic reasons. METHODS New CLs (soft or GP) fittings were retrospectively analyzed and divided into refractive and therapeutic prescriptions. A standardized fitting protocol that included complete CLs information after a first(More)
PURPOSE To compare the current optometric practices and attitudes in the management of keratoconus patients in the UK and Spain. METHODS An online survey (adapted to optometric practices) was distributed via a newsletter emailed by various professional organizations in the UK and Spain. RESULTS Four hundred and sixty-four practitioners (126 in the UK;(More)
