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

Journal 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.

The use of a “horizontal centrifugation protocol” to prepare autologous platelet‐rich fibrin membranes for corneal reconstruction surgery in dogs with complicated corneal ulcerations: A case series

Veterinary Ophthalmology, Volume 28, Issue 2, Page 175-189, March 2025.
Abstract Objective The purpose of this case series was to describe the effect of autologous PRF membrane for corneal reconstruction surgery in dogs. PRF membranes made from two healthy dogs unrelated to the current case series were used for PRF histologic analyses. Animals Seven dogs with complicated corneal ulcerations. Procedure A complete ophthalmic

Comparative analysis of intraocular pressure measured with non-contact air tonometry (Tonopachy NT-530P) and non-contact tonometer with detection of corneal biomechanical response (OCULUS Corvis ST) [PDF]

, 2022
Introduction:The measurement of intraocular pressure (IOP) is one of the standard tests in performing an ophthalmology examination. These values are among the parameters used to diagnose and monitor one of the commonly seen socially significant diseases ...

Vision outcomes in dogs with primary glaucoma surgically treated with lensectomy and endolaser cyclophotocoagulation after an Ahmed valve gonioimplantation failure

Veterinary Ophthalmology, Volume 28, Issue 2, Page 207-217, March 2025.
Abstract Objective The aim of this study was to retrospectively evaluate vision outcomes of dogs with primary angle closure glaucoma (PACG) that underwent Ahmed valve gonioimplantation (AVG) followed by lensectomy and endolaser cyclophotocoagulation (ECP) with or without bleb resection after AVG failure.

Non-contact tonometry in patients that underwent photorefractive keratectomy

, 1997
To determine the accuracy of non-contact tonometry in patients with corneas thinned by photorefractive keratectomy, the authors measured the intraocular pressure with a non-contact tonometer and the corneal thickness with an ultrasonic pachymeter in 47 ...

Modalities of Tonometry and their Accuracy with Respect to Corneal Thickness and Irregularities

Journal of Optometry, 2008
Recent advances in tonometry have led to the development of a number of devices with differing clinical applications. Their role in cases of abnormal corneal thickness and surface irregularities is particularly important, as inaccurate estimation of the ...
