# Glaucoma surgery success rates

Glaucoma surgery success rates vary with procedure type, disease severity, and individual healing. Success usually means keeping pressure low enough to slow or stop further damage.

## What counts as success

Rather than perfect numbers, clinicians look for stable optic nerves and visual fields. Some patients still need drops even when surgery has worked well.

- Target pressures are set according to how advanced the glaucoma is
- Trabeculectomy and tube surgery often achieve larger pressure drops
- MIGS typically offers moderate reductions with quicker recovery
- Scarring, age, and other eye conditions can influence outcomes

## Long-term follow-up and expectations

Results are best judged over years, not days. Regular reviews check that the benefit continues.

- Pressure may slowly creep up, sometimes needing further treatment
- Additional procedures or laser can refresh a failing bleb or device
- Healthy lifestyle and adherence to remaining drops still matter
- Open conversation about goals helps align expectations with likely results
