PURPOSE The purpose of this study was to evaluate the effect of chronic epithelial scrape injury on corneal morphology. METHODS The corneal epithelia in one eye of 8-week-old New Zealand White rabbits were scraped at weekly intervals. Central corneal thickness was measured by ultrasonic pachymetry before epithelial scrape each week. Control never wounded (C), chronic wounded with scrape the l...

BACKGROUND Intraocular pressure (IOP) in the developing eye of a child is not always easy to measure and there is no technique that is known to be the most accurate for the young eye. Measurements are needed on many cohorts of children with different tonometers to determine how the values correlate between instruments, whether corneal parameters affect readings and whether correlations between ...

In the article “Topographic Analysis of the Centration of the Treatment Zone After SMILE for Myopia and Comparison to FS-LASIK: Subjective Versus Objective Alignment” by Lazaridis et al.,1 a corneal thickness difference map was used to determine centration. The authors concluded that “the corneal thickness differential map in Scheimpflug-based systems is a useful tool to display the treatment z...
