PURPOSE The purpose of this study was to describe the visual prognosis as well as the frequency and clinical severity of central nervous system involvement in all acute posterior multifocal placoid pigment epitheliopathy (APMPPE) patients of one centre. METHODS A retrospective database review of all patients and a prospective clinical, ophthalmological(More)
PURPOSE To determine the repeatability of keratometry of the Verion image-guided system and to compare the keratometry (K) values with those of established biometric devices. SETTING International Vision Correction Research Centre, Department of Ophthalmology, University of Heidelberg, Heidelberg, Germany. DESIGN Prospective case series. METHODS One(More)
PURPOSE To describe a severe case of keratomycosis caused by Arthrographis kalrae requiring repeated keratoplasty. METHODS A 42-year-old otherwise healthy soft contact lens wearer developed a unilateral central corneal ulcer. Treatment with topical and systemic voriconazole is described. RESULTS Repeated microbiological testing of ocular swabs (culture)(More)
PURPOSE To evaluate functional results and corneal changes after femtosecond laser correction of presbyopia (INTRACOR, Technolas Perfect Vision GmbH) in emmetropes using a modified treatment pattern over a 12-month period. METHODS Twenty eyes from 20 emmetropic patients were treated with a modified intrastromal INTRACOR pattern consisting of 5 central(More)
Aniridia is defined as missing iris tissue which can be partial, subtotal or total. Characteristic clinical symptoms include photophobia and decreased visual acuity due to an increased light perception. In addition, disturbing cosmetic problems are prevalent. Modern iris reconstruction implants offer visual and cosmetic rehabilitation. Amongst them are(More)
PURPOSE The aim of this study was to perform a clinical evaluation of the functional results and quality of vision after implantation of an aspheric, aberration-neutral, monofocal intraocular lens (IOL). PATIENTS AND METHODS 47 eyes of 34 patients (median age: 68 years) with cataract were enrolled in this prospective clinical study that had Ethics(More)
PURPOSE To analyze the influence on intraocular lens (IOL) power calculation of corneal radii measured by the Verion Image-Guided System in comparison with those measured by partial coherence interferometry (PCI) (IOLMaster) and optical low-coherence reflectometry (OLCR) (Lenstar) systems. SETTING International Vision Correction Research Centre,(More)
PURPOSE To analyze the refractive outcomes and safety of three-piece silicone toric sulcus-fixated add-on intraocular lenses (IOLs) (HumanOptics/Dr.Schmidt Intraocularlinsen, Erlangen, Germany) in complex clinical cases with high astigmatism such as in cases with previous penetrating keratoplasty. METHODS Interventional case series of 21 eyes of 20(More)
BACKGROUND/AIMS To assess over a 36-month period functional results of the modified INTRACOR femtosecond laser-based intrastromal procedure to treat presbyopia. METHODS 20 eyes of 20 presbyopic patients with mild hyperopia were included. The INTRACOR procedure with a modified pattern (six concentric intrastromal ring cuts) was performed using the FEMTEC(More)
