# What to expect after YAG laser iridotomy

After YAG laser iridotomy, most people feel mild discomfort and notice some light sensitivity. The procedure aims to prevent sudden pressure spikes in angle-closure glaucoma by creating a tiny drainage hole in the iris.

## Immediately after the laser

Pressure-lowering and anti-inflammatory drops are used around the procedure. Vision can be hazy for a few hours due to dilating and numbing drops.

- You may feel a slight ache, scratchiness, or headache.
- Some people see coloured haloes or glare temporarily.
- Small floaters are common but usually fade with time.
- The clinic will check eye pressure shortly after treatment.
- You will be given drops to use at home and a follow-up appointment.

## Short-term recovery and safety

Most symptoms improve over a few days. Ongoing monitoring ensures that the iridotomy stays open and pressure remains controlled.

- Use your prescribed drops exactly as directed.
- Report severe pain, haloes with blur, or nausea urgently.
- Glare from lights should gradually lessen as the eye settles.
- Regular glaucoma checks remain important long term.
- Sometimes a second laser session is needed if the opening narrows.
