Incidence of Acanthamoeba Keratitis in Switzerland Open
Despite rising global reports of Acanthamoeba keratitis (AK), the incidence of AK in Switzerland remains unknown. This investigator-initiated, retrospective, multicenter study assessed the nationwide incidence of PCR- and/or culture-positi…

Burr-Assisted Peripheral Superficial Keratectomy for the Treatment of Persistent Symptomatic Peripheral Corneal Edema Open
Peripheral superficial keratectomy could be an effective alternative for the treatment of peripheral, symptomatic corneal edema.

Combined Astigmatic Arcuate Keratotomy with Descemet Automated Endothelial Keratoplasty Open
We report the results of simultaneous astigmatic arcuate keratotomy (AK) and Descemet automated endothelial keratoplasty (DSAEK). A 55-year-old patient with a history of high myopia was referred for the management of bullous keratopathy se…

Intraocular Lens Refractive Index and Its Impact on External Surface Reflections Open
PURPOSE: To determine and compare the origin of the external surface reflections produced by commonly used intraocular lenses (IOLs). METHODS: The specular reflection taking place at the anterior surface of eight types of IOLs (IOL power =…

Topographic changes simulating keratoconus in patients with irregular inferior epithelial thickening documented by anterior segment optical coherence tomography Open
Epithelial irregularity, as measured by anterior segment OCT, should be considered as a possible contributing factor in the appearance of suspicious keratoconus-like topographies.

Peripheral hypertrophic subepithelial corneal degeneration: clinical aspects related to in vivo confocal microscopy and optical coherence tomography Open
AS-OCT and IVCM can facilitate the diagnosis of PHSD and differentiate it from other corneal entities that present peripheral opacifications.

Intraoperative anterior optical coherence tomography-guided synechiolysis in a post-penetrating keratoplasty patient with peripheral corneal opacification Open
Intraoperative OCT is useful to overcome the difficulties in visualization through clinically opaque corneas, as it gives real-time feedback upon the anatomy, the extension of the remaining lesions, and the success of the surgery.

Melanopsin-Mediated Acute Light Responses Measured in Winter and in Summer: Seasonal Variations in Adults with and without Cataracts Open
Seasonal adaptation is a ubiquitous behavior seen in many species on both global hemispheres and is conveyed by changing photoperiods. In humans this seasonal adaptation is less apparent, in part because changes in daylength are masked by …

Tolerance and Relative Utility: Two Proposed Indices for Comparing Change in Clinical Measurement Noise Between Different Populations (Repeatability) or Measurement Methods (Agreement) Open
Reaching a consensus in terms of interchangeability and utility (i.e., disease detection/monitoring) of a medical device is the eventual aim of repeatability and agreement studies. The aim of the tolerance and relative utility indices desc…
