Evaluation of interface quality in organ-cultured lamellar corneal transplants [PDF]

, 2012
Background: With increasing numbers of lamellar keratoplasties, eye banks are challenged to deliver precut lamellar donor tissue. In Europe, the most common technique of corneal storage is organ culture which requires a deswelling process before surgical

Corneal ectasia following cataract extraction surgery in a patient with keratoconus: a case report

Journal of Medical Case Reports, 2019
Background According to experimental and clinical published studies, patients with keratoconus have a genetic predisposition to corneal ectasia; however, ectasia might not be activated or reactivated unless an additional stressful event triggers the ...

Intraocular pressure, corneal thickness, and corneal hysteresis in Steinert's myotonic dystrophy [PDF]

Arquivos Brasileiros de Oftalmologia, 2011
Low intraocular pressure (IOP) measured by Goldmann applanation tonometry (GAT) is one of the ocular manifestations of Steinert's myotonic dystrophy. The goal of this study was to evaluate the corneal-compensated IOP as well as corneal properties (central corneal thickness and corneal hysteresis) in patients with myotonic dystrophy.A total of 12 eyes ...

Increased Corneal Hysteresis After Corneal Collagen Crosslinking [PDF]

JAMA Ophthalmology, 2014
A reliable tool for quantification of the biomechanical status of the cornea in conjunction with corneal collagen crosslinking (CXL) treatment is needed.To quantify the biomechanical effects of CXL in vivo.A prospective, open, case-control study was conducted at the Department of Ophthalmology, Umeå University, Umeå, Sweden.

Bio‐inspired vision: From principle, material architectures to system‐level integration

FlexMat, EarlyView.
This review introduces the development and mechanism of electronic and ionic bio‐inspired vision devices respectively. Then, it explores the impact of structure on bio‐inspired visual performance from the scale of intrinsic materials and device. Finally, it concludes that only by combining advanced software and technology can more complex vision ...

Two‐Photon Endomicroscopy for Image‐Guided Magnetic Micro‐Agents

Small, EarlyView.
Image‐guided manipulation of magnetic micro‐agents requires localized fluorescence feedback capable of resolving dynamic interactions in confined environments. This study introduces a two‐photon endomicroscopy platform for real‐time motion tracking, multicolor micro‐agent discrimination, and imaging through biological tissue.

Genetic risk factors in Finnish patients with Fuchs endothelial corneal dystrophy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To study the genetic risk factors of Fuchs endothelial corneal dystrophy (FECD) in the Finnish population using hospital‐based and large biobank cohorts. Methods We genotyped a cohort of 107 Finnish patients with FECD for the primary associated genetic risk factor, the TCF4 (CTG)>50 expansion, and studied their clinical phenotype.
