Repeatability of intra-ocular pressure and central corneal thickness measurements provided by a non-contact method of tonometry and pachymetry

摘要

Background To examine the repeatability of intra-ocular pressure (IOP) and central corneal thickness (CCT) measurements provided by the Tono-Pachymeter NT530P (Nidek, Japan), and to assess agreement of the device with Goldmann applanation tonometry (GAT) and ultrasound pachymetry (UP).
