Research output: Contribution to journalArticle


The objective of this research was to assess the repeatability of Orbscan measures on right versus left eyes. Three Orbscan measures were taken from the right eye and then the left eye by the same operator on 50 healthy myopic subjects (average right eye = -4.3 DS) aged 19 to 58 years, half of whom were successful long-term soft contact lens (SCL) wearers. The central point thickness measurement was compared for the 3 scans for each eye, the variability calculated based on the coefficient of variation (COV) and also paired comparisons with limits of agreement.
