This study looks at how well glaucoma microstents are positioned after surgery in adults who also had cataract surgery, to see if their placement affects eye pressure over time.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older who have undergone Hydrus microstent or iStent Inject placement at the Moran Eye Center.
✕Probably not a fit
Patients who have had their stent removed or have a history of anterior segment trauma or anatomical alterations will not benefit from this study.

What this trial studies
This observational study aims to evaluate the long-term outcomes of glaucoma microstent surgery in adults who have also undergone cataract surgery within the last two years. Participants will undergo a one-time eye exam and Optical Coherence Tomography (OCT) to assess the positioning of microstents and the dilation of Schlemm's canal. Researchers will analyze medical records to gather data on surgeon experience and the effectiveness of the surgery based on changes in intraocular pressure. The study seeks to determine the frequency of microstent mispositioning and its impact on intraocular pressure post-surgery.
Why it matters
Potential benefit: If successful, this study could improve the understanding of microstent positioning and its effects on intraocular pressure, leading to better surgical outcomes for glaucoma patients.
How similar studies have gone: While this study focuses on specific outcomes related to microstent positioning, similar observational studies have shown promise in understanding surgical outcomes in glaucoma treatment.
