Influence of artificial tears on corneal parameter measurement using three different devices: Keratometry and Scheimpflug technology, a randomized trial

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To evaluate the effect of artificial tear (AT) application on the repeatability of corneal parameters with three different devices. Methods In this prospective, randomized clinical trial, 145 patients were measured with one of three devices in the Department of Ophthalmology, Goethe University, Frankfurt, Germany.

Considerations on the Haigis formula: Are better outcomes possible with tuning?

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To design a vergence‐based lens power formula based on the classical Haigis formula for better outcomes while retaining the original formula architecture. Methods Four new formula variants (A–D) incorporating a sum of segments correction for axial length, harmonic mean of corneal radii instead of arithmetic mean (all variants), and ...

Molecular and cellular mechanisms underlying gyrate atrophy: Why is the retina primarily affected?

open access: yesActa Ophthalmologica, EarlyView.
Abstract Gyrate atrophy of the choroid and retina (GACR; OMIM #258870) is a rare early‐onset autosomal recessive disorder, caused by bi‐allelic pathogenic variants in the gene coding for ornithine aminotransferase (OAT) resulting in hyperornithinaemia.
