High-Precision Measurement of Binocular Telecentric Vision System With Novel Calibration and Matching Methods

IEEE Access, 2019
In stereo vision-based three-dimensional measurements, calibration, and stereo matching are the most challenging tasks for accurate three-dimensional reconstruction. The traditional binocular vision algorithm has low precision, and we propose a binocular

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

Improving Operator Depth Vision in Gastrointestinal Endoscopy: A Pilot Study of a New Three‐dimensional Imaging System

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Background and aims Traditional two‐dimensional (2D) gastrointestinal endoscopy lacks depth perception, leading to potential diagnostic errors. This study evaluates a novel software‐based three‐dimensional (3D) endoscopy system that converts 2D images into 3D, compatible with existing endoscopes.

Visual acuity outcomes up to 12 years and risk factors for visual impairment in a national cohort of extremely preterm born children – The Extremely Preterm Infants in Sweden Study (EXPRESS)

Acta Ophthalmologica, Volume 104, Issue 1, Page 65-74, February 2026.
Abstract Purpose The Extremely Preterm Infants in Sweden Study (EXPRESS) followed a national cohort of extremely preterm born (EPT, i.e. <27 weeks) children until 12 years of age. This study aimed to investigate the longitudinal development of visual acuity (VA) in children born EPT, explore the predictive value of early visual assessments, and ...
