Changes in Eye Pressure in Glaucoma Patients Treated with Istent Inject W, Monitored by a Contact Lens Sensor

This study monitors eye pressure changes around the clock in glaucoma patients who have received a tiny implant called iStent inject W, which helps drain fluid from the eye to lower pressure. Participants wear a special contact lens sensor that continuously tracks eye pressure to give doctors a more complete picture than occasional office measurements. **You may be eligible if...** - You are 18 years or older - You have been diagnosed with primary open-angle glaucoma (POAG), normal tension glaucoma (NTG), or ocular hypertension (elevated eye pressure without glaucoma damage) - You have received the iStent inject W implant as part of your treatment - Your untreated eye pressure was above 21 mmHg at diagnosis **You may NOT be eligible if...** - You have conditions that caused your elevated eye pressure (e.g., narrow angles, blood vessel growth on the iris, inflammation) - You cannot tolerate the contact lens sensor - You do not meet the diagnostic criteria for POAG, NTG, or ocular hypertension Talk to your doctor to see if this trial is right for you.
