The CYCLO G6 is a specialised diode laser (810 nm) for the treatment of glaucoma using transscleral cyclophotocoagulation (TSCPC). It is one of the most popular non‑invasive / minimally invasive laser devices for reducing intraocular pressure (IOP).
Primary Indication
- Treatment of all stages of glaucoma (open‑angle, angle‑closure, refractory).
- Reduction of aqueous humour production by targeting the ciliary body.
- Used both in an outpatient setting (clinic room) and in the operating room.
Key Technologies
- MicroPulse® (micropulse mode) – gentle, tissue‑sparing. The laser beam is divided into short micro‑pulses with pauses → minimal inflammation, low risk of hypotony, and the possibility of repeat procedures.
- Continuous Wave (CW) – classic continuous mode (for traditional TSCPC).
Main Probes (Accessories)
- MicroPulse P3® (MP3) – the primary probe for micropulse treatment. The most popular, gentle, and repeatable.
- G‑Probe® – for classic CW cyclophotocoagulation.
- G‑Probe Illuminate® – with built‑in transillumination (backlighting) for precise positioning.
- Probes are single‑use sterile items with RFID identification (SmartProbe).
Technical Specifications
- Wavelength: 810 nm (infrared).
- Power: 50–3000 mW.
- Modes: CW‑Pulse and MicroPulse.
- Cooling: air‑cooled (compact, portable).
- Weight: approximately 3.9–4.8 kg.
- Controls: touchscreen, illuminated buttons, foot pedal (wired/wireless), optional remote control.
- Power supply: 100–240 V.
Advantages
- Non‑invasive approach (no incisions).
- Minimal inflammation and pain.
- Can be used in early and late stages, including refractory glaucoma.
- Repeatability of procedures.
- Good safety profile (used in leading clinics in the USA and worldwide).
- IOP reduction of approximately 30–45% on average (depending on mode and stage).
This is a workhorse for glaucoma surgeons, especially when an alternative to medication or filtering surgery is needed.
