TRABECULAS / Q-LAS

Superior Coupling

The best solution for a combination unit with a SLT laser and photodisruptor on one slit lamp, is using the Haag slit lamp with A.R.C. coupling. The unique coupling of the Trabeculas laser with the Haag-Streit slit lamp offers true coaxial beam delivery of slit lamp light, laser and aiming beam.

The best optical quality for diagnosis and treatment

Versatility

Diagnosis and treatment on the same slit lamp, one after each other, is only possible with the A.R.C. coupling without any loss in optical quality just by a quick switch.
The coupling mirror of the Trabeculas laser can be removed from the system just by this quick switch, which results in original slit lamp illumination for capsulotomy with the Q-Las 10.

Easy application

Controlled Energy

The Trabeculas laser provides ultra short laser pulses for treating the trabecular meshwork without any destructive effect. This allows repeat treatments to increase treatment results and lower intraocular pressure on demand.The Q-las 10 laser energy is checked every time the energy settings are changed. This provides controlled capsulotomies with adequate energy deposition.

Non-destructive glaucoma treatment and controlled capsulotomies
