About

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.

22 participants in 2 patient groups

EyeCheck

Experimental group

Description:

EyeCheck pressures will be measured with contact lens in place

Treatment:

Device: EyeCheck

Traditional Tonometer (Goldmann and Tonopen)

Active Comparator group

Description:

Pressures will be measured with both Goldmann and Tonopen (both traditional tonometers to take the intraocular pressure (IOP) measurements of the eye).
