SLT or laser iridotomy
General information. Follow the individual instructions from your treating team. These pages do not prescribe treatment or replace an examination.
What you may notice
The purpose and follow-up differ between these laser treatments. Keep your written discharge instructions.
Two different treatments
- SLT improves fluid drainage through the trabecular meshwork in open-angle disease. Follow-up checks pressure and treatment response; drops may still be needed.
- Iridotomy makes a small opening in the iris to help treat or prevent angle closure in selected eyes. Follow-up checks pressure, whether the opening remains patent, and the drainage angle.
Care at home
Continue or change your glaucoma drops only as your treating clinician instructs. Do not stop them because the laser is complete.
Follow-up & recovery
Confirm when your pressure will be checked. Severe pain, headache with nausea, or reduced vision needs urgent assessment.
Before returning to activities
Ask your team about washing, bathing, swimming, exercise, driving, work, contact lenses, makeup and any eye protection. Confirm your follow-up and who to contact if no appointment arrives. Feeling better does not replace the planned review.
Seek urgent help
Sudden or worsening vision, severe or increasing pain, increasing redness or swelling, or new flashes or a curtain over vision need urgent assessment. Do not wait for your next appointment or a WhatsApp reply.
