Capsulotomy and Iridotomy

The Q-LAS gives you the possibility to treat secondary cataracts and the wide-angle-glaucoma. It links economy, ergonomics and longevity in a very innovative way.

  • Outstanding focusing with the two-part laser beam
  • Combination with CLASSIC
  • Laser beam and slit illumination are coaxial

Dual spot focus

The concept is to overlay 2 spots - This dual spot focus from A.R.C. Laser supports you effectively to position your laser.

Delivery Range

Combined systems

The Q-LAS can be combined with the CLASSIC retina laser. Furthermore, the Q-LAS is available with two different types of slit lamps.


  • With a classical YAG slit lamp
  • Illumination radiation channel through prism


  • Light source at the tip of the slit projector
  • High end optical quality
