Assessing the likely effect of posterior corneal curvature on Toric IOL calculation for IOLs of 2.50 D or greater cylinder power

open access: yes, 2017
Purpose: To establish whether average refractive overcorrection or undercorrection of corneal astigmatism based on the orientation (rule) of the astigmatism occurs if toric intraocular lenses (IOLs) are calculated on the basis of anterior corneal ...

Multi‐site performance of the telemedicine retinopathy of prematurity severity score (tROP‐SS)

open access: yesActa Ophthalmologica, EarlyView.
Abstract Objective This study aims to evaluate the performance of the telemedicine retinopathy of prematurity severity score (tROP‐SS) across all 14 NICUs in the TELEROP cohort against the modified ROP activity score (mROP‐ActS). Design Retrospective cohort study. Subjects The study included 2037 neonates who underwent ROP screening in 14 NICUs via the

Corneal Posterior Curvature Changes After Phacoemulsification Cataract Surgery with 2.75 mm Corneal Incision

open access: yes, 2019
The aim of this study was to evaluate the corneal posterior curvature changes after phacoemulsification cataract surgery, with intraocular lens implantation, with a temporal limbal self-sealing 2.75 millimeters (mm) corneal incision, using a Placido-dual

Repeatability of keratometry depending on tear film osmolarity

open access: yesActa 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),

Femtosecond Laser Created Corneal Allogenic Intrastromal Ring Segments for Keratoconus

open access: yesClinical &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.

Corneal parameter changes after cataract extraction [PDF]

open access: yes, 1995
National health services are receiving increased pressure to improve cost efficiency and quality of patient treatment outcome. Hence it is useful to re-evaluate corneal changes following cataract extraction, with a view to minimising astigmatism and ...

Aqueous Humour Cytokines as Predictors of Axial Elongation in High Myopia: A 2‐Year Longitudinal Cohort Study

open access: yesClinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background To investigate the predictive value of aqueous humour cytokines for axial elongation. Methods This was a prospective longitudinal observational study. 72 high myopia patients (72 eyes) who received implantable collamer lens (ICL) implantation surgery with at least 2 years of follow‐up were included.

Assessment of two minimally invasive methodologies for sex identification in the European eel, Anguilla anguilla

open access: yesJournal of Fish Biology, EarlyView.
Abstract Sex is an important driver of variation in behaviour, ecology and physiology. Sex identification in the Critically Endangered European eel (Anguilla anguilla) currently requires fish sacrifice, or the use of morphological differences such as body length, which can be inaccurate in certain habitats and at intermediate body lengths.

Results of ethanol-assisted epithelium-on corneal cross-linking with and without intrastromal corneal ring implantation

open access: yes, 2018
To evaluate the topographic, refractive, and pachymetric changes after ethanol-assisted transepithelial corneal cross-linking (CXL) to stabilize progression of keratoconus (KC).This study retrospectively evaluated the long-term topographic, refractive ...

Reduced order modelling of air‐puff test for corneal material characterisation

open access: yesJournal of Microscopy, EarlyView.
Abstract Models of the fluid–structure interaction (FSI) model for the air‐puff test were analysed. Using Abaqus, the air‐puff test is applied to eyes with varying biomechanical parameters, such as material properties, corneal thickness, and radius.
