The Influence of Central Corneal Thickness and Corneal Curvature on Intraocular Pressure Measured by Tono-Pen and Rebound Tonometer in Children

Abstract

Both the Tono-Pen and RBT have a systematic error in IOP readings caused by its dependence on CCT. The CCT measurements should be considered to ensure proper interpretation of IOP measurements in children, like in adults. The corneal radius of curvature had no significant effect on measured IOP with each device.
