Astigmatic changes after Descemet membrane endothelial keratoplasty (DMEK) in decompensated penetrating keratoplasty grafts

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate the surgery‐induced changes of astigmatism after Descemet membrane endothelial keratoplasty (DMEK) in eyes with failed previous penetrating keratoplasty (PK). Design Retrospective, interventional cohort study based on prospective DMEK database.

Astigmatism and Pseudoaccommodation in Pseudophakic Eyes [PDF]

, 2010
noAdvanced IOLs with circumferential zones of different power provide pseudoaccommodation. We investigated the potential for power variation with meridian, namely astigmatism, to provide pseudo-accommodation. With appropriate power and axis orientations,

Changes in choroidal and retinal thickness 6 months before and during 18 months of orthokeratology lens treatment in myopic children

Acta Ophthalmologica, EarlyView.
Abstract Purpose To investigate changes in choroidal and retinal thickness before and during myopia control treatment with orthokeratology lenses (OKL) in myopic children. Methods This was a sub‐study of CONTROL and CONTROL2 studies. The present study was a 2‐year, prospective, single‐group interventional study consisting of a 6‐month pre‐treatment ...

Repeatability of keratometry depending on tear film osmolarity

Acta Ophthalmologica, EarlyView.
Abstract Purpose To determine the repeatability of keratometry and astigmatism measurements of patients depending on the tear film osmolarity using three different devices. Methods In this study, 97 eyes of 97 patients with a mean age of 64.92 ± 12.07 years received three repeated measurements with the IOLMaster 700 (Carl Zeiss Meditec, Jena, Germany),

The differences in essential facial areas for impressions between humans and deep learning models: An eye‐tracking and explainable AI approach

British Journal of Psychology, EarlyView.
Abstract This study explored the facial impressions of attractiveness, dominance and sexual dimorphism using experimental and computational methods. In Study 1, we generated face images with manipulated morphological features using geometric morphometrics. In Study 2, we conducted eye tracking and impression evaluation experiments using these images to

Astigmatism-type-specific impact of peripheral corneal thickness on anterior keratometric profile changes after temporal clear corneal incision cataract surgery

Scientific Reports
Postoperative astigmatism remains a concern after temporal clear corneal incision (TCCI) cataract surgery, especially in eyes with preexisting corneal astigmatism. This study investigated whether peripheral-to-central corneal thickness ratios can predict

Intraocular Metastasis: Differential Diagnosis and Management

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Intraocular metastases represent the most common type of malignant intraocular tumour in adults. These commonly affect the choroid but can also involve the iris, ciliary body, retina, vitreous, optic disc or lens. Breast and lung cancer are the most common origins of intraocular metastases.

Femtosecond Laser Created Corneal Allogenic Intrastromal Ring Segments for Keratoconus

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background To evaluate the clinical outcomes of femtosecond laser‐created corneal allogenic intrastromal ring segments (femto‐CAIRS) in keratoconic eyes using a newly described nomogram. Methods This retrospective case series recruited 85 eyes from 75 patients.
