Two people can both be told they're having “IPL for dry eye” and receive completely different treatment.
IPL is a category of technology, not a single procedure. The device, the eyelids treated, what happens after the light, who is holding the handpiece and whether anyone measured your eyes beforehand all change what you actually get. Here is precisely what happens in our chair at Eyecare Project, and where it differs from what else is offered.
Is all IPL the same?
No. “IPL” describes a broad family of light-based devices, most of which were built for cosmetic skin work and later pointed at the eyelids. Only one has been through a regulatory process specifically for dry eye.
We treat with Lumenis OptiLight, which uses the company's patented Optimal Pulse Technology (OPT®). In 2021 it became the first and, to date, the only IPL device granted FDA authorisation specifically for improving the signs of dry eye disease caused by meibomian gland dysfunction. That authorisation rests on a multi-centre, double-blinded, randomised controlled trial, and the technology now carries more than 50 published studies behind it.
What makes it different is not brightness. It is control. OPT shapes every pulse so the energy arrives evenly from the first millisecond to the last, rather than as a spike followed by a tail. Around eyelid skin that is less than a millimetre thick, that difference is the difference between a therapeutic dose and a burn.

Devices you may see offered elsewhere are not equivalent, and some are not IPL at all:
Lumenis OptiLight · OPT®
The only IPL device with FDA authorisation for dry eye, granted through the De Novo pathway on the strength of a multicentre, double-blinded randomised controlled trial. Its OPT waveform shapes every pulse so the energy arrives evenly rather than as a leading spike, filtered to a 590 to 1200 nm band. Energy is set against your Fitzpatrick skin type and reset at each visit as the inflammatory vessels recede, instead of running as a fixed course. Ultrasound gel cools the skin and couples the light into it. With corneal shields or adhesive IPL metal shield stickers in place it is delivered directly to the lid margin, upper and lower, and every session finishes with the glands expressed.
E-Eye · IRPL
The IRPL system. Each flash delivers a fixed sequence of sub-pulses between 580 and 1200 nm, applied as five overlapping flashes under the lower eyelid. By design it does not treat the upper lid at all, which is where the greater number of meibomian glands sit, and it is not applied to the lid margin itself. Its FDA clearance is for rosacea rather than for dry eye, and it is typically delivered as a set three-session protocol on predetermined days rather than adjusted to how your glands respond. Its stated mechanism is different too: it aims to stimulate the glands indirectly through a nerve branch running beneath the cheekbone, rather than settling the inflamed vessels along the lid margin.
OPE™ · Eye-Light
Espansione's OPE emits polychromatic light in thermal impulses. It holds CE marking in Europe but no FDA authorisation for dry eye, which is a different and lower bar. It is also a different emission technology, so the trial evidence behind that authorisation does not carry across to it. It runs without coupling gel, which is quicker, though that gel also cools the skin surface and evens out how light enters it, and that matters more as skin tone deepens.
Rexon-Eye · QMR®
Quantum molecular resonance: a low-power, high-frequency electrical current (roughly 4 to 64 MHz) delivered through an electrode mask over closed eyes. A legitimate technology with its own evidence base, but an entirely different mechanism. It does not target the inflammatory and vascular drivers on the lid margin that IPL is used for.
Beauty-market IPL
Salon hair-removal systems and home handsets use wide, unfiltered spectra with little pulse control and no eye-specific safety framework. Used near the eye they carry a real risk of iris damage and pigment loss. These are not dry eye devices.
Do you treat the upper eyelids, or only the lower?
Both, every time.
Your meibomian glands sit in both lids, and the upper lid holds the greater number of them. A course that treats only the lower lid leaves most of the tissue causing the problem untouched, which is a significant limitation when the whole aim is to restore the oil layer that stops your tears evaporating.
Most clinics treat the lower lid and cheek area only. That is the simpler application: the light is kept below the eye and no internal eye protection is needed. Treating the upper lid requires corneal shields to be placed under the lids first, which is an additional skill, an additional consumable and additional chair time. We consider it a core part of the treatment rather than an optional extra.
What happens after the light?
Meibomian gland expression of the upper and lower lids, at every single session, without exception.
This is the part most often left out, and it is the part that does much of the work. The light warms and liquefies hardened oil and settles the inflammation feeding the problem; expression is how that softened, stagnant oil is physically cleared out of the glands so they can start flowing again. Light without expression leaves the blockage where it was.
Elsewhere this step is often performed on the lower lid only, at some sessions rather than all, or skipped entirely. For us it is not a discretionary add-on. Every session ends with all four lids expressed and reassessed.
The FDA authorisation for this treatment is itself written for use alongside meibomian gland expression. The two belong together.
How is the equipment cleaned between patients?
Stainless steel expression paddles, sterilised in our own medical autoclave between every patient.
Expression means applying firm, controlled pressure to the lid margin, against tissue that is often already inflamed, and directly beside the ocular surface. The instrument doing that should be built for the job and genuinely sterile.
Purpose-made paddles let us apply even, measured force along the full length of the lid, so glands are actually emptied rather than squeezed unevenly. Cotton buds and fingertips, still common practice, cannot deliver that force reliably, shed fibres onto the ocular surface, and cannot be sterilised at all. Autoclaving is the same standard used for surgical instruments; wiping something down between patients is not the same thing.
Is everyone given the same course of treatment?
No. No two dry eye presentations are the same, so no two protocols are.
Dry eye is a category, not a diagnosis. Evaporative, aqueous-deficient and mixed presentations behave differently. Blocked glands, ocular rosacea, demodex infestation of the lash line, an incomplete blink and lid laxity all sit under the same set of symptoms and all need different handling.
What we adjust for each person:
- Energy level, set against your Fitzpatrick skin type rather than a default applied to everybody
- Which structures are treated, and whether treatment is applied along the lid margin directly
- Session spacing and course length, guided by how your glands actually respond
- What runs alongside it: lid hygiene, demodex management, targeted anti-inflammatories, blink retraining, or investigating a cause we have not accounted for yet
A fixed number of identical sessions sold as a set is convenient to advertise. It is not, in our view, a considered response to a chronic and highly variable condition.
How will I know whether it actually worked?
Because we measured your eyes before we started, and we measure them again afterwards.
Every course begins with a full dry eye assessment and baseline imaging. That gives us objective numbers and images to return to, rather than relying on whether a treatment “felt” like it helped, which is a poor guide in a condition where symptoms fluctuate week to week and often correlate badly with the signs.
What we record at baseline:
- Meibography: infrared imaging of the glands themselves, showing which are intact, which have shortened and which have been lost
- Tear film stability: how many seconds your tear film holds before it breaks up
- Lipid layer assessment: the thickness and quality of the oil covering your tears
- Gland expressibility and meibum quality, graded lid by lid
- A validated symptom score, so your experience is tracked as data too
Those measures are repeated through the course. If it is working, we can show you where and why. If it is not, we can see that just as clearly, and change direction instead of finishing the set and hoping.
This is the single largest difference between a dry eye service and a light treatment. Delivering IPL or LLLT without baseline data means there is no way to demonstrate improvement, and no way to know when the plan needs to change.
Who performs the treatment?
An optometrist, every session, start to finish.
Not a therapist, not an assistant, not a technician following a protocol sheet. The same clinician who examined your eyes, read your scans and set your plan is the one holding the handpiece.
This matters for two reasons. The first is safety: IPL around the eye carries real risks including burns, pigment change and ocular damage, and judging energy against skin type, spotting a contraindication and adapting mid-treatment requires clinical training. The second is judgement. What your glands do under expression, how the lid margin looks that day and how your tear film has changed all inform the next session. That information is only useful if the person seeing it is qualified to act on it.
How long is a session?
Forty minutes. Unrushed, by design.
It takes that long to do it properly. Shields placed and settled, skin prepared, light applied across both lids, shields removed, all four lids expressed, the ocular surface reassessed, and time to talk through what has changed since last visit and what to do at home before you leave.
Compressing this into a fifteen-minute appointment is possible, but only by removing something. Usually it is the expression, the upper lids, or the conversation.
How are my eyes protected during treatment?
With either corneal shields placed under the lids or adhesive metal IPL shield stickers applied over the closed eyes, depending on the treatment area and technique being used.
Goggles resting on the face are not sufficient protection when treatment is delivered directly over the eyelids.
We use one of two protective options:
- Corneal shields, inserted after anaesthetic drops and positioned between the eyelid and the eye, allowing treatment close to the lid margin
- Adhesive metal IPL shield stickers, placed over the closed eyes to provide external protection when internal shields are not required
Some clinics use neither corneal shields nor adhesive metal shield stickers, usually because treatment is kept below the eye rather than delivered directly to the eyelids. We do not apply IPL over the eyelids without one of these protective options in place.
Why come here for this?
Because dry eye is what we do, every day.
Eyecare Project is a dedicated dry eye clinic in Hawthorn. The majority of the people in our waiting room are here for their tear film, their glands or their lid margins, not for a routine check. We run dry eye assessments and treatments daily, which is what builds the pattern recognition that matters: recognising the presentation that will not respond to IPL alone, catching the demodex nobody looked for, knowing when to stop and reinvestigate.
For a general practice, IPL is one service among many, delivered occasionally. For us it is one part of a treatment pathway we work in constantly, backed by imaging, measurement and follow-up.
The treatment you have with us is not really the forty minutes of light. It is the assessment that decided light was the right answer, the protocol built around your particular presentation, the expression at every visit, and the data telling all of us whether it is working.
