Arms of the Study
Arm 1
Arm 2
Arm Type
Experimental
Active Comparator
Arm Label
EyeCheck
Traditional Tonometer (Goldmann and Tonopen)
Arm Description
EyeCheck pressures will be measured with contact lens in place
Pressures will be measured with both Goldmann and Tonopen (both traditional tonometers to take the intraocular pressure (IOP) measurements of the eye).
Outcomes
Primary Outcome Measures
Intraocular pressure (IOP) measurements
Compare EyeCheck intraocular pressure (IOP) measurements comparable to those of traditional tonometers (Goldmann and tonopen)
