Cataract, Glaucoma
Conditions
Brief summary
This study is a prospective comparative, randomized, single center study to gather agreement and precision data in all subjects.
Interventions
DEVICECornea/Anterior Segment OCT CASIA2
Cornea/Anterior Segment OCT CASIA2 The Tomey Cornea/Anterior Segment OCT CASIA2 is a non-contact, high resolution tomographic and biomicroscopic device indicated for the in vivo imaging and measurement of ocular structures in the anterior segment, such as corneal thickness. The Tomey Cornea/Anterior Segment OCT CASIA2 is indicated as an aid in the visualization of anterior segment findings.
DEVICEOptovue RTVue XR Avanti
Optovue RTVue XR Avanti The Avanti is an optical coherence tomography system indicated for the in vivo imaging,axial cross-sectional, and three-dimensional imaging and measurement of anterior and posterior ocular structures.

Exclusion criteria
- Normal Group: 1. Subjects unable to tolerate ophthalmic imaging; 2. Subjects with any current ocular pathology, as determined by self-report and confirmed by the investigator assessment and/or confirmed by the investigator assessment at the study visit; 3. Subjects that present with an active ocular infection in either eye; 4. Subjects who have a history of ocular surgery, including laser therapy/surgery; 5. Subjects with a condition or in a situation which the investigator feels may put the subject at significant risk, may confound the study results, or may interfere significantly with the subject's participation in the study. Inclusion Criteria - Cataract Group: 1. Male or female subjects 22 years of age or older who have full legal capacity to volunteer on the date the informed consent is signed; 2.
