This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether endoscopic cyclophotocoagulation—a laser procedure that reduces pressure inside the eye—should be performed during cataract surgery in patients with normal tension glaucoma. Right now, patients with this type of glaucoma have stable eye pressure while on medication, but researchers want to know if adding the laser treatment during cataract surgery could provide additional benefit. The study will compare patients who have cataract surgery alone to those who have cataract surgery combined with this laser treatment.
Normal tension glaucoma is a type of vision loss that occurs even when eye pressure stays within normal ranges, which makes it tricky to manage. Researchers are investigating whether this laser treatment during cataract surgery could help slow or prevent further vision loss in these patients.

You would be randomly assigned to either have cataract surgery alone or cataract surgery combined with the laser treatment—both performed in the same session. Your eye doctor will monitor your eye pressure and vision over time to see whether adding the laser treatment helps protect your sight better than surgery alone. You'll need to attend follow-up appointments so researchers can compare how well each approach works for managing your glaucoma.
