MicroPulse cyclophotocoagulation for glaucoma

A gentle, non-incisional laser that lowers eye pressure by easing back the eye's fluid production. Delivered in tiny on-off pulses through the Cyclo G6 laser, MicroPulse transscleral laser therapy (MP-TLT) treats glaucoma without cutting into the eye — and can be repeated if needed.

MicroPulse cyclophotocoagulation (MicroPulse transscleral laser therapy, MP-TLT) is a non-incisional laser treatment that lowers eye pressure in glaucoma by gently reducing how much fluid the eye produces. The Cyclo G6 laser delivers energy in short on-off "micropulses" through the white of the eye, which is gentler than older continuous laser. It takes only a few minutes per eye, needs no cut or stitch, and can be repeated. At our partner clinics it starts from £2,000 per eye.

What is MicroPulse cyclophotocoagulation?

Glaucoma damages the optic nerve, usually because the pressure inside the eye is too high. That pressure is set by a balance between fluid (aqueous humour) made by the ciliary body and fluid draining away. Cyclophotocoagulation works on the production side: a laser is applied over the ciliary body to calm it down, so the eye makes a little less fluid and the pressure falls.

The MicroPulse approach chops the laser into rapid pulses with rest gaps in between. This lets the tissue cool between pulses, treating the ciliary body more gently than traditional continuous cyclophotocoagulation. The result is effective pressure-lowering with a lower risk of the inflammation and side effects associated with the older technique — so it can be considered across a wider range of glaucoma, not only advanced cases.

Who is it for?

  • Glaucoma not controlled by drops alone, or where drops are poorly tolerated
  • Patients who want to reduce their reliance on glaucoma drops
  • Eyes unsuitable for, or that have already had, incisional or MIGS surgery
  • People who prefer a quick, non-incisional day-case option

It is suitable for many types of glaucoma. Your consultant confirms whether MP-TLT is right for you after reviewing your pressures, optic nerve and visual fields.

How it compares to other glaucoma treatments

MicroPulse laser is one of several ways to lower eye pressure. It is often chosen as a non-incisional step before or alongside surgery.

Laser

SLT laser

Treats the eye's drainage angle to improve outflow. Often a first-line laser. See Direct SLT.

Surgery

MIGS & drainage

Stents and shunts that improve drainage, such as iStent, Hydrus or PreserFlo.

For more involved disease, options include trabeculectomy. Your surgeon will explain where MicroPulse laser fits in your personal treatment plan — see our overview of glaucoma treatment.

What happens during the procedure

MicroPulse cyclophotocoagulation is performed under local anaesthetic as a day case. You stay awake, and the laser itself takes only a few minutes per eye.

  1. The eye is numbed with a local anaesthetic injection around the eye (sub-Tenon or peribulbar block).
  2. You lie back comfortably while the surgeon places the MicroPulse P3 probe against the white of the eye, just outside the coloured iris.
  3. The Cyclo G6 laser is swept smoothly over the treatment zone, delivering energy in rapid on-off pulses to the ciliary body beneath.
  4. The probe is moved across the upper and lower halves of the eye for a set time — typically a few minutes in total.
  5. The eye is rinsed and a drop or ointment applied. There is no incision and no stitch.

Recovery week-by-week

Recovery is usually straightforward. The eye is a little red and sore at first, and the pressure-lowering effect builds over the following weeks.

Day of treatment

Mild ache, redness and light sensitivity are normal. Anti-inflammatory drops begin. You go home the same day.

Days 1–7

Discomfort settles. Continue your usual glaucoma drops unless told otherwise. Avoid rubbing the eye.

Weeks 2–6

The full pressure-lowering effect develops. Your consultant rechecks your eye pressure and adjusts drops if appropriate.

Ongoing

Pressure and optic nerve are monitored long-term. If more reduction is needed, MicroPulse laser can be repeated.

Frequently asked questions

Does MicroPulse laser hurt?
The eye is fully numbed with local anaesthetic, so you should not feel pain during the treatment. Afterwards the eye may ache mildly and feel gritty for a day or two, which settles with drops.
Will I still need my glaucoma drops?
Many patients reduce the number of drops they need, and some can stop one or more. Whether you can cut back depends on how much your pressure falls — your consultant will advise after rechecking your eye.
How is MicroPulse different from older cyclodiode laser?
Traditional cyclophotocoagulation uses continuous laser and was mainly reserved for advanced glaucoma because of a higher risk of inflammation. MicroPulse delivers the laser in short on-off pulses that let tissue cool between bursts, making it gentler and suitable for a wider range of glaucoma.
Can it be repeated?
Yes. Because it is non-incisional and gentle, MicroPulse laser can be safely repeated if more pressure reduction is needed over time.
What are the risks?
MicroPulse laser is well tolerated, but possible effects include temporary inflammation, mild pressure spikes, light sensitivity and, less commonly, a change in pressure that needs further treatment. Your consultant will discuss your individual risks at consultation.
