Treatment
Tixel Treatment for Dry Eyes
Two minutes of precisely limited heat, conducted through the eyelid skin to the glands behind it. Tixel uses no light at all, which is why it works the same way on every skin tone and at every time of year.
- Duration
- 2 – 5 minutes
- Sessions
- 3, two weeks apart
- Comfort
- Brief hot pulses, well tolerated
- Downtime
- None; mild warmth for a few hours
What Tixel treats in dry eye disease
Tixel is used for evaporative dry eye, the form driven by meibomian gland dysfunction. The meibomian glands sit in vertical rows inside the upper and lower lids and release the oil that seals the tear film. When that oil thickens it stops leaving the gland, the tear film loses its lid, and the water underneath evaporates within seconds of a blink. That is the burning, gritty, worse-by-evening feeling most patients arrive with.
The treatment addresses the thickened oil itself rather than the symptoms it causes. Because it is a heat treatment and not a light treatment, skin colour, a recent tan and the season are all irrelevant to it.
How Tixel works on the meibomian glands
- 01Titanium tip at 385 – 405 °C
- 02Contact of six thousandths of a second
- 03Heat conducted into the lid skin
- 04The tarsal plate warms
- 05Waxy meibum softens and flows
Conducted heat, not light
The handpiece carries a small titanium tip set with 24 blunt pyramids. The tip is held between 385 and 405 °C and touches the eyelid skin for about six thousandths of a second at a time. In that instant heat passes into the skin by direct conduction, the way a warm hand warms a cold one.
Nothing is emitted: no laser, no light, no radiofrequency. Each pyramid holds only a fixed, very small amount of energy, so the peak heat the eyelid can receive is capped by physics rather than by the steadiness of the operator’s hand.
What the warmth does to the meibum
Ten pulses are placed along each lid. The warmth reaches the tarsal plate, where the glands lie, and softens meibum that has turned waxy. In a healthy eye meibum melts a little below the surface temperature of the lid, so it flows out with every blink.
In meibomian gland disease its composition shifts and its melting point rises above the temperature the lid naturally reaches, so it stiffens and stays where it is. Restoring that temperature difference is what allows the gland to empty again. A rigid shield sits under the lids throughout, so the eye itself is never exposed to the tip.
Tixel is the one treatment in the Smart Dry Eyes programme that is tied to a single technology. Everything else on this site is described independently of any manufacturer.

What a Tixel session is like
Before
A drop of anaesthetic is placed on the eye and a rigid shield is slid under the lids. Numbing ointment on the skin is available but most patients do not need it.
During
Ten pulses along each of the four lids. Each pulse feels like a short, sharp warmth. The whole treatment takes under two minutes.
After
The shield comes out and you leave. You can drive, work and read straight away. Mild warmth or pink skin along the lid can last a few hours.
The course
Three sessions two weeks apart. The improvement builds across the course rather than arriving after the first visit.
What the evidence shows for Tixel
Randomised, five centres, 106 patients
The strongest study to date is a randomised, evaluator-masked trial across five centres in which 106 patients received either Tixel or LipiFlow, the established thermal pulsation treatment (Sadri and colleagues, Journal of Cataract & Refractive Surgery, 2025). Tear break-up time improved by roughly three seconds in both groups at four and at twelve weeks, and Tixel met the statistical threshold for non-inferiority. Symptom scores improved somewhat more in the Tixel group. Patients also reported the Tixel pulses as briefly less comfortable than LipiFlow.
What the smaller studies do and do not show
Two earlier studies were smaller and had no control group (Safir and colleagues, 2022; Shah and colleagues, 2023). They support the finding rather than establish it. All three were funded or co-authored by people connected to the manufacturer, and no sham-controlled trial of Tixel in dry eye has been published. Non-inferiority to LipiFlow means Tixel is not worse than an accepted treatment; it does not mean it is better than one.
Dr. Ludger Hanneken, medical director of the Smart Dry Eyes network, is a co-author of Shah and colleagues (2023) and is disclosed in that paper as an advisor to Novoxel.
Who Tixel suits, and who it does not
Usually a good fit
- Evaporative dry eye with confirmed meibomian gland dysfunction
- Darker or recently tanned skin, where IPL is restricted or unsafe
- Patients who want the shortest treatment in the programme
- Anyone treated year-round, including through the summer
Not suitable, or postponed
- Pregnancy or breastfeeding
- Isotretinoin taken in the past twelve months
- Active eye infection, or herpes simplex or zoster
- Eye surgery within the past six months, or existing punctal plugs
- Bleeding disorders, anticoagulant treatment, or keloid scarring
- Aqueous-deficient dry eye such as Sjögren’s syndrome, where the glands are not the problem
What it costs
Europe
Tixel, full course of three sessionsfull course
from €800

Entry prices. What you pay depends on the centre, on how many sessions your diagnosis calls for, and on whether treatments are combined. In Germany these are private-pay treatments: statutory insurers do not reimburse them, private insurers and Beihilfe often do, in part. Your centre confirms the figure before anything begins.
Tixel questions
Does Tixel hurt?
Each pulse is a short, distinct heat that most patients describe as sharp rather than painful, and it is over in milliseconds. In the trial that compared the two directly, patients rated Tixel as briefly less comfortable than LipiFlow. Numbing ointment is available if you would rather have it.
How long does the effect last?
Reported benefit runs to about six months in the published follow-up. Clinics sometimes quote nine to twelve months; the trials do not go that far, so treat longer figures as claims rather than findings. Most patients return for a maintenance session once symptoms begin to creep back.
Can I have Tixel if my skin is dark, or if I am tanned?
Yes. This is the practical difference between Tixel and IPL. IPL relies on light being absorbed by pigment, so it is restricted by skin type and by recent sun exposure. Tixel transfers heat by touch, so neither applies.
Tixel or IPL?
They do different things. Tixel warms the glands so thickened oil can leave them. IPL works on the inflamed vessels along the lid margin that keep the glands irritated. Patients with visible redness and ocular rosacea usually benefit more from IPL; patients whose main problem is blocked, waxy glands usually benefit more from heat. The two are often used together.
