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.

Natural Aging of Biomaterials in Ambient and Physiological Environments

Advanced NanoBiomed Research, EarlyView.
Biomaterials used in biomedical applications can change their physical properties over time, even under ambient and physiological conditions. This review highlights key studies on the natural aging of materials ranging from soft hydrogels to metals and ceramics, emphasizing how time‐dependent changes influence function and performance.

One‐Year Results of Accelerated Transepithelial Corneal Cross‐Linking for Progressive Keratoconus: A Prospective Interventional Study

Eye &ENT Research, EarlyView.
ABSTRACT Background Keratoconus is a progressive corneal ectatic disorder. Accelerated transepithelial corneal cross‐linking (ATE‐CXL) aims to halt progression while preserving the epithelium, but evidence on its 12‐month efficacy requires further evaluation.
