New laser therapy for advanced and end-stage glaucoma
* Not for sale in the US
Ergonomic and easy to use, Vitra 810 is versatile infrared laser featuring single spot and subliminal technologies which can be used for multiple treatment purposes.
When used for glaucoma treatments, Vitra 810 offers a new subthreshold cyclophotocoagulation treatment procedure named SubCyclo, a very promising laser therapy for advanced and end-stage glaucoma patients.
Key features:
- 810nm infrared wavelength for transscleral treatments
- SubLiminal subthreshold mode for tissue sparing treatments
- Nondestructive SubCyclo glaucoma laser procedure improving the uveoscleral drainage
- One laser: Two clinical applications (Glaucoma and Retina treatments)
Proprietary 810nm SubLiminal emission mode
Composed of a train of extremely short microsecond pulses of which the duration and the intervals are fully adjustable, this subthreshold treatment mode allows a precise management of the thermal effect on the targeted tissues.
The use of this subthreshold emission mode is the cornerstone of the new SubCyclo® glaucoma laser therapy.
Enhanced software interface
Vitra 810 provides an intuitive and versatile user interface simplifying glaucoma and retina laser treatments.
Built in a clinically oriented manner, it features 4 different software guided treatment procedures.
A simple and versatile laser
Fully portable and perfectly sized for use in operating room and doctor’s office, Vitra 810 is compatible with various delivery systems such as SubCyclo probes, Slit lamp, Microscope, LIO and retina laser probes.
One single laser probe: two glaucoma treatments
Quantel Medical laser probe is uniquely designed with a removable footplate allowing implementing both SubLiminal and thermal treatment procedures.
SubLiminal Cyclophotocoagulation (SubCyclo)
SubCyclo is a nondestructive laser procedure for the treatment of glaucoma.
Based on the transcleral cyclophotocoagulation principle, the SubCyclo procedure relies on the 810nm SubLiminal laser stimulation of the ciliary body, producing the aqueous humor, and the uveoscleral pathway, secondary route of the aqueous outflow.
It can be performed thanks to the combined use of the Vitra 810 laser and the SubCyclo probe.
A Novel non destructive cyclophotocoagulation procedure
As efficient as the thermal cyclophotocoagulation procedure, SubCyclo preserves the structures of the ciliary body (no destructive effects) and avoids the side effects of the thermal cyclophotocoagulation procedure. [1,2]
Improving the uveoscleral and trabecular outflow it is a safe and repeatable procedure, potentially allowing for earlier laser interventions. [1,2]
SubCyclo Mechanisms of action
Clinical and experimental studies reported that the SubCyclo could involve:
- A selective destruction of pigmented ciliary body causing minimal coagulative necrosis of ciliary body decreasing the aqueous humor production [3]
- An uveoscleral remodeling increasing the uveoscleral and transscleral aqueous outflow [3]
- An action on the longitudinal fibers of the ciliary muscle, causing a displacement of the scleral spur modifying the configuration of the TM and the outflow tract of the aqueous humor [3]
