Intense Pulsed Light

IPL treatment — relief from dry eye

Dry eye disease and chronic blepharitis are inflammatory conditions of the eye's surface, often caused by meibomian gland dysfunction. For a long time, they were treated only with artificial tears or anti-inflammatory drugs. Since 2002, thanks to the work of Dr Russell Toyos in ophthalmology, IPL (Intense Pulsed Light) treatment has expanded the available care. At the OPHTALIFE practice in Boulogne-Billancourt, just outside Paris, I offer a 4-session protocol that targets the underlying mechanisms: liquefying clogged secretions, destroying abnormal blood vessels, eliminating Demodex mites and modulating inflammation. The result: a gradual and lasting improvement in comfort.

Understanding the technology

What is IPL?

IPL (Intense Pulsed Light) is a non-ablative technology that originated in dermatology and is now used in ophthalmology to treat meibomian gland dysfunction. I have also written a blog article about this technology: “IPL for dry eyes: the complete guide”.

Definition & technology

IPL emits polychromatic light covering a range of wavelengths: 500 to 1200 nanometers. Unlike a laser (a single wavelength), this spectral diversity allows a multifactorial, non-invasive action on the eyelid and periorbital tissues.

The light is delivered in short pulses (a few milliseconds), with precisely controlled intensity and duration. It penetrates the skin to a depth of a few millimeters, generating localized heat without abrading the surface.

IPL is a non-invasive, outpatient treatment: no incision, no stitches, no recovery time.

History in ophthalmology

IPL has been used in dermatology since the 1990s to treat acne, rosacea and erythema. In 2002, Dr Russell Toyos (United States) had the idea of applying it to ocular rosacea and meibomian gland dysfunction. Since then, more than 20 years of publications have supported its effectiveness.

I have offered this treatment since 2023 at the OPHTALIFE practice, always guided by the OSDI score, a comprehensive ocular surface assessment (TBUT, fluorescein, meibography), and the indications validated by professional societies (TFOS DEWS II, SFO).

IPL is not a cure-all, but it is a key tool in the stepwise management of dry eye disease.

How it works

The 4 mechanisms of action of IPL

IPL acts simultaneously on four disease processes, which explains its overall and lasting effectiveness on dry eye disease and blepharitis.

01 — Thermal

Meibum liquefaction

The heat generated by IPL raises the eyelid temperature to about 40-45 °C — above the melting point of meibomian secretions, which are abnormally thick in MGD. They liquefy and regain their fluidity for the manual expression that follows (Borchman 2011, Goldberg 2014).

02 — Vascular

Selective photothermolysis

IPL targets the dilated, abnormal blood vessels (telangiectasias) responsible for redness and rosacea. The heat partially destroys them, reducing chronic inflammation.

03 — Anti-Demodex

Thermal elimination

Demodex mites colonize the eyelash follicles. IPL reduces the Demodex population, thereby lowering the overall inflammatory burden (Cheng 2019, Zhang 2019).

04 — Anti-inflammatory

Immune modulation

IPL reduces pro-inflammatory cytokines (TNF-α, IL-6, IL-8) and MMP-9. This lasting anti-inflammatory effect improves the ocular surface.

Who can benefit?

Indications & contraindications

IPL is not for everyone. A consultation is essential to assess your eligibility and optimize the results.

Main indications
  • Moderate to severe meibomian gland dysfunction (MGD)
  • Chronic posterior blepharitis
  • Ocular rosacea (redness, telangiectasias)
  • Refractory dry eye disease (not responding to artificial tears)
  • Dry eye after LASIK or PRK
  • Confirmed or suspected demodicosis
  • Chronic functional tearing
  • Anterior blepharitis associated with seborrheic dermatitis
Contraindications (relative or absolute)
  • Skin phototype VI — very dark skin (risk of burns)
  • Recent tan (less than 2 weeks)
  • Photosensitizing drugs: isotretinoin, tetracyclines
  • Pregnancy (relative contraindication — to be discussed)
  • History of lupus, photodermatosis or porphyria
  • Melanoma or suspicious pigmented lesion around the eye
  • Photosensitive epilepsy
  • Uncontrolled herpes simplex in the treatment area
  • Hypertrophic scarring (history of keloids)

Important: Skin phototypes V and VI are not absolute contraindications. Adjusting the settings (reduced fluence, skin masking) can make treatment possible. A thorough consultation is mandatory.

The treatment plan

The 4-session protocol

Regular spacing, cumulative effects, clinical follow-up. Here is how we structure your IPL treatment at the practice.

Duration per session
15 minutes
Recommended interval
2 weeks
Pain level
2-3/10
Return to activities
Immediate
Visible effects
From month 1
Optimal effect
After month 3
Session 1 — Day 0 (Baseline)

A full OSDI assessment, TBUT (tear break-up time) test, fluorescein and lissamine green staining, and meibography. Discussion of your expectations. First IPL session with settings adapted to your skin phototype and severity. Manual expression of the meibomian glands after IPL.

Session 2 — Day 15

Quick clinical check (slit lamp). Second IPL session with a slight increase in fluence depending on tolerance. Gland expression. Liquefaction of the meibum starts to become visible.

Session 3 — Day 30

Assessment of clinical signs (redness, perceived dryness). Third IPL session at optimal intensity. This session consolidates the anti-inflammatory effect and continues the elimination of Demodex.

Session 4 — Day 45

Final IPL session, completing the protocol. Post-treatment ocular surface assessment (staining, TBUT, osmolarity). Recommendations for long-term maintenance.

Follow-up — Months 3, 6 and 12

Clinical follow-up visit and OSDI questionnaire. If progress is good, annual maintenance is possible. In case of partial recurrence at 6-12 months, a second series of 2-4 sessions may be offered.

Minute by minute

What happens during a session

15 simple, painless minutes. Here is exactly what happens at the practice.

Welcome & positioning

You are seated comfortably in a suitable examination chair, in a semi-reclined position, tilted slightly backward.

Cleansing (make-up removal)

The eyelids are carefully cleansed with a gentle lotion. All cosmetic residue is removed, which is important for the IPL light to penetrate effectively.

Eye protection

I place two sterile, opaque metal eye shields, specifically designed for ophthalmic IPL, which fully protect the eyes and lashes. You may perceive a faint glow through your closed eyelids, but no direct light enters the eye.

Cold coupling gel

A generous layer of clear, cold coupling gel is applied to the lower eyelids and periorbital area. This gel helps transmit the light and cools the skin, reducing discomfort.

IPL pulses (8-15 per side)

I guide the handpiece (applicator) over the eyelids. You will feel tingling and a light elastic-band “snap” with each pulse — a tolerable sensation, 2-3/10 on the pain scale. Duration: about 10 minutes for both eyes.

Mechanical gland expression

After removing the gel, I perform manual expression of the meibomian glands (MGX) using dedicated forceps (Maskin or Mastrota). It is painless and allows the liquefied secretions to be cleared.

Cleansing & SPF

The protective shields are removed and the gel is cleaned off. I apply SPF 50 sunscreen to the treated eyelids.

Advice & discharge

Immediate return to activities. You leave the practice and carry on with your day as normal. A few tips: avoid chlorinated water for 48h, wear sunglasses, make-up is possible after 24h.

What to expect

Sensations & experience

During the session

During the session, your eyes are protected by the opaque metal shields. Most patients describe:

  • Mild tingling on the eyelids
  • A light elastic-band snap with each pulse
  • A pleasant feeling from the cold gel at first, then slight warmth
  • A mild, well-tolerated sensation for the vast majority of patients
  • A very faint smell of heat — this is normal

After the session

You leave the practice with no restrictions on activity:

  • Eyelid erythema (redness): present for 24-48 hours, then fades
  • No significant swelling (mild at most)
  • Mild tearing possible during the first few hours (normal)
  • Make-up: wait 24 hours
  • Contact lenses: a 48-hour wait is recommended
  • Sports, swimming: resume immediately
  • SPF 50 is mandatory on the treated area for 1 week

Important advice: Apply a gentle moisturizer after 24 hours. Avoid chlorinated water and very hot water (showers). These precautions support optimal skin healing.

Measurable progress

What results can you expect?

IPL is not a permanent cure, but it provides lasting stabilization of the ocular surface. Here is a realistic timeline.

Sessions 1-2
Weeks 1-4

During the protocol, a slight improvement in subjective symptoms (less stinging). Clinical signs improve gradually (less eyelid redness).

M1-2
1 to 2 months after the 4th session

Noticeable improvement. The OSDI score drops (fewer symptoms). You notice less stinging at the end of the day, better tolerance of screens and more comfortable night driving.

M3
3 months: the optimal point

Optimal results. Increased TBUT (more stable tears), improved staining tests, normalized osmolarity. How you feel overall: eyes that feel “free,” with lasting, noticeable everyday comfort.

M6-12
6 to 12 months: stabilization

Results are maintained. Depending on the initial severity, the benefits remain stable for 6-12 months or even longer. In case of mild recurrence, a maintenance course of 1-2 sessions can reinforce the effect.

A realistic view: IPL is not a “permanent cure” but an effective treatment for a chronic condition that stabilizes meibomian gland dysfunction. As with most chronic inflammatory diseases of the ocular surface (dry eye, blepharitis), the goal of treatment is to stabilize rather than to cure. Annual maintenance is often recommended for more severe cases.

Scientific basis

The scientific evidence

IPL is not a gimmick. Since 2002, more than 20 years of peer-reviewed publications have supported its clinical effectiveness and its mechanisms of action.

Proven effectiveness

The Cochrane systematic review protocol by Cote et al. (2020) and subsequent reviews report low- to moderate-quality evidence in favor of IPL for meibomian gland dysfunction, with improvements in TBUT and OSDI; the published protocols remain highly heterogeneous.

The retrospective observational study by Toyos et al. (2015, Photomed Laser Surg) reports symptom improvement in most patients treated with IPL combined with meibomian gland expression (MGX). This is the landmark study that popularized IPL in ophthalmology; the first randomized controlled trial is Craig et al. (2015, IOVS).

Craig et al. (2015), a prospective, randomized, split-face study in New Zealand (n = 28): IPL significantly improved TBUT, lipid layer quality and symptoms compared with the control side.

The retrospective series by Vegunta et al. (2016, Cornea) reports good results with combined IPL + meibomian gland expression (MGX). It has no IPL-only arm, so this study does not formally demonstrate the superiority of the combination — it is nevertheless the protocol I use routinely at the practice.

The literature review by Fineide et al. (Acta Ophthalmologica, 2024) summarizes around fifty studies: a favorable effect on MGD, heterogeneous levels of evidence, and exceptionally rare serious adverse effects.

In 2023, I published a major literature review entitled EYERUBBICS: The Eye Rubbing Cycle Study in the Journal of Clinical Medicine (DOI 10.3390/jcm12041529). With the team at the CHNO des Quinze-Vingts (Paris) and Prof. Christophe Baudouin, we showed how dry eye creates a vicious circle of eye rubbing, which in turn worsens inflammation and tear film instability.

This understanding is crucial: IPL does not treat meibomian gland dysfunction in isolation. It also breaks this vicious circle by reducing inflammation (less urge to rub) and stabilizing the tears (less of the gritty sensation that triggers rubbing), and so quickly restores your comfort. That is why I recommend IPL early in the course of care, as soon as dry eye is confirmed.
