This review evaluates the outcomes of intrastromal corneal ring segment (ICRS) implantation for the treatment of keratoconus considering a new grading system based on the preoperative visual impairment of the patient. Additionally, a five-year follow-up analysis of patients with stable and progressive keratoconus is performed in order to assess the long(More)
INTRODUCTION Seasonal allergic conjunctivitis (SAC) is a highly prevalent condition that exacts a range of costs from its sufferers. The aim of this study was to examine quality of life (QoL) and economic consequences of SAC amongst private health care patients in Spain. METHODS 201 sufferers of SAC and 200 controls were recruited from four private eye(More)
PURPOSE To analyze the outcomes of intracorneal ring segment (ICRS) implantation for the treatment of keratoconus based on preoperative visual impairment. DESIGN Multicenter, retrospective, nonrandomized study. METHODS A total of 611 eyes of 361 keratoconic patients were evaluated. Subjects were classified according to their preoperative corrected(More)
PURPOSE To compare the outcomes of laser in situ keratomileusis (LASIK) performed with a femtosecond laser vs a mechanical microkeratome for the correction of low to moderate hyperopia. DESIGN Retrospective, nonrandomized, interventional, comparative case series. METHODS settings: Vissum Santa Hortensia, Madrid, Spain.study population and procedures:(More)
PURPOSE To determine the correlation between refractive and keratometric astigmatism in pseudophakic eyes. SETTING Vissum Madrid, Madrid, Spain. DESIGN Case series. METHODS Consecutive eyes that had phacoemulsification with intraocular lens implantation during the first quarter of 2003 were evaluated. The refractive and keratometric astigmatism were(More)
PURPOSE To characterize the refractive, keratometric, and corneal aberrometric effect of a specific type of intracorneal ring segment (ICRS) as a function of its thickness and the preoperative conditions of the cornea. METHODS A total of 72 consecutive keratoconic eyes of 57 patients ranging in age from 15 to 68 years were retrospectively analyzed and(More)
PURPOSE To evaluate the clinical features of keratoconus taking into consideration anterior corneal aberrations, internal astigmatism, and corneal biomechanical properties and to define a new grading system based on visual limitation. SETTING Vissum Corporation, Alicante, Spain. DESIGN Retrospective case series. METHODS This multicenter study(More)
PURPOSE The aim of this study was to evaluate the efficacy and safety in ocular hypertensive or open-angle glaucoma patients changed to a latanoprost/timolol fixed combination (LTFC) from previous therapy. METHODS We employed a retrospective, multicenter, active-controlled study evaluating patients who had a previous therapy substituted with LTFC and had(More)
PURPOSE To determine the main causes of intrastromal corneal ring segment (ICRS) explantation and the relationship with the microscopic findings on the ICRS surface. SETTING Vissum Corporation-Instituto Oftalmológico de Alicante, Alicante, Spain. METHODS This study evaluated ICRS that were explanted in centers in Spain from 2000 to 2008. Clinical data(More)
PURPOSE To evaluate two silicone hydrogel contact lens materials as continuous-wear bandage contact lenses after laser-assisted subepithelial keratomileusis (LASEK). METHODS The inclusion criteria were myopia of -6.00 diopters (D) or less, astigmatism lower than -1.5 D, bilateral best-corrected visual acuity of 20/20 or better, and candidates for(More)
