24-hour Wear Performance and Safety Study of Smartlens miLens Contact Lens for IOP Monitoring
Trial Parameters
Brief Summary
The goal of this clinical trial is to learn if a new contact lens device can record patterns in eye pressure for 24 hours in adults with glaucoma and in healthy participants. The main questions it aims to answer are: * Is the contact lens device able to detect patterns in eye pressure that happens naturally between nighttime and daytime? * Are the contact lens recording patterns similar when repeated one week later? * What eye problems do participants have when wearing contact lens for up to 24 hours? Researchers will compare if the recordings detected by the contact lens over 24 hours are similar to the patterns measured by an eye pressure measuring instrument used in a doctor's office. Participants will * Wear contact lens in one eye for up to 24 hours * Take recordings in that eye with smartphone camera every 15 minutes when awake * For those participants who are able to stay overnight at a hotel for the trial, researchers will measure the eye pressure in the other eye every 1 to 2 hours when awake with an eye pressure measuring instrument.
Eligibility Criteria
Inclusion Criteria: 1. Subjects ≥22 to ≤80 years of age 2. Subjects with: * prior diagnosis of POAG in at least one eye, including normal tension glaucoma or prior diagnosis of POAG suspect including OHTN in at least one eye for whom no evidence or suspicion of structural or functional glaucomatous damage exists * Diagnosis of POAG from medical records characterized by open angles and (1) optic nerve cupping consistent with glaucoma, with diffuse or focal thinning of neuroretinal rim or nerve fiber layer defects or a difference in cup/disc ratio \> 0.2, not explained by anisometropia or other non-glaucomatous causes (2) visual field defects consistent with optic nerve cupping, with glaucomatous hemifield test outside normal limits or a pattern standard deviation (PSD) worse than 5th percentile (P\<0.05) by Standard Automated Perimetry, or VF defects with Goldmann visual field test consistent with glaucomatous nerve fiber layer loss including paracentral scotoma, nasal step or arcuate d
