TSCPC is performed externally using a diode laser (810 nm). It is performed under local anaesthesia in the operating theatre as a day-care procedure. A probe is placed on the surface of the eye, and laser energy is delivered at multiple spots.
TSCPC is used particularly in cases of refractory glaucoma, painful blind eyes, or complex types such as neovascular and uveitic glaucoma. It’s especially valuable in eyes with limited visual potential, as it provides an accessible option for patients with a poor prognosis.
This procedure is mainly performed to attempt to lower intraocular pressure and not to improve vision. However, the technique carries significant risks, such as overtreatment leading to hypotony (abnormally low eye pressure) or, in severe cases, phthisis bulbi (shrinkage of the eyeball). Patients may also experience post-procedure pain, inflammation, bleeding inside the eye (hyphema), and, rarely, more serious complications like cystoid macular edema or sympathetic ophthalmia.
Following this procedure, patients are typically prescribed topical steroids to help control inflammation, alongside close monitoring of intraocular pressure and pain management in the early postoperative period. In selected cases, the treatment may be repeated cautiously, depending on the eye’s response and residual pressure control.
The success rate of cyclophotocoagulation varies depending on the technique used and the underlying indication. Traditional transscleral cyclophotocoagulation (TSCPC) has shown an intraocular pressure (IOP) reduction success rate ranging from 50% to 80%. Cyclo G6 offers similar efficacy in lowering IOP but is associated with a better safety profile and fewer postoperative complications, making it a preferred option in eyes with some visual potential.
You may feel a slight sting or pressure during the treatment. Numbing eye drops are used beforehand to minimize discomfort.TSCPC might be a little painful, but it will be done under local anaesthesia.
Possibly. Some patients can reduce or stop their glaucoma medications after successful laser treatment, while others may still need to use drops to maintain target pressure.
No, laser treatment does not cure glaucoma. It helps manage the condition by lowering eye pressure to prevent or slow further vision loss.
Most patients can return to normal activities within a day, but it’s best to avoid strenuous activity.
Yes.
