Intense pulsed light (IPL) therapy uses brief flashes of broad‑spectrum light applied to the skin around the eyes to treat meibomian gland dysfunction and some lid vascular problems. It is adapted from dermatological use for rosacea and telangiectasia.
Mechanism in Dry Eye
IPL is thought to reduce abnormal blood vessels and inflammation around the lids, warming and improving the function of meibomian glands that supply the oily layer of the tear film. This can decrease evaporative dry eye symptoms.
- Treatment involves a series of sessions with protective eye shields
- Cooling gel and precise settings minimise skin discomfort
- Often combined with lid expression or other dry eye therapies
- Multiple maintenance sessions may be needed for sustained benefit
Safety and Suitability
IPL is generally well tolerated when delivered by trained practitioners but is not suitable for all skin types or conditions. Careful screening avoids risks such as pigment changes or burns.
- Patients should avoid tanning and certain medications before treatment
- Mild redness or warmth of treated skin is common temporarily
- Results vary, and IPL is usually part of a comprehensive dry eye plan
- Eye protection is critical to avoid retinal or corneal injury
