Pseudoexfoliation Glaucoma study: Phacoemulsification
Official title Phacoemulsification vs SLT as Initial Treatment for Pseudoexfoliation Glaucoma
ClinicalTrials.gov ID: NCT04416724
What this study is testing
- What it's testing
- The study aims to find out which of two initial treatments is better for lowering eye pressure in patients with pseudoexfoliation glaucoma.
- Who it's for
- The study is looking for people recently diagnosed with pseudoexfoliation glaucoma who need to lower their eye pressure and have early, mild clouding of the eye lens.
- What's involved
- Participants will be randomly assigned to receive either a laser treatment or a cataract surgery. They will be monitored to see if they need eye drops later.
- Time commitment
- The study involves active follow-up for 2 years, with additional record checks at 5 and 10 years.
