Glaucoma, Normal Tension Glaucoma, Ocular Hypertension
Conditions
Brief summary
The CATS Tonometer prism clinical study is intended to determine repeatability of intraocular pressure measurement in human corneas which have undergone a LASIK procedure when compared to a standard Goldmann prism, validating the human LASIK eye findings comparing CATS Tonometer and Goldmann prisms to intracameral pressure in cadaver eyes.
Interventions
DEVICEThis is observational IOP measurement
IOP measurement of patients having LASIK with both CATS and GAT
