# What is micropulse laser trabeculoplasty?

Micropulse laser trabeculoplasty (MLT) is a newer form of glaucoma laser that delivers energy in short pulses with intervening cooling periods. It targets the trabecular meshwork like ALT or SLT but aims to reduce thermal damage.

## Technique

Using a contact lens at the slit lamp, the laser applies a sequence of micropulses to the drainage angle. The duty cycle limits heat build‑up, potentially improving safety and repeatability.

- Usually performed under topical anaesthetic as an outpatient
- Post-procedure discomfort and inflammation are typically mild
- Eyes may continue or adjust pressure-lowering drops afterwards
- Evidence suggests pressure reduction comparable to other trabeculoplasty methods in many patients

## Place in Treatment

MLT can be considered for open‑angle glaucoma or ocular hypertension, especially when non‑destructive, repeatable therapy is desired. Long-term comparative data are still evolving.

- Pressure response is monitored over subsequent weeks
- MLT may be repeated if effect diminishes
- Not all patients respond, so ongoing monitoring and alternative options are essential
- It does not replace the need for regular glaucoma follow-up
