Reliability and Reproducibility of the Eye Check Tonometer

Reliability and Reproducibility of the Eye Check Tonometer Pressure Measurements as Measured by Patients Reliability and Reproducibility of the Eye Check Tonometer Pressure Measurements as Measured by Patients

To investigate whether the new applanation tonometer (EyeCheck monitor) can provide intraocular pressure (IOP) measurements comparable to those of traditional tonometers such as the Goldmann applanation tonometer and the Tonopen.
