Nano-Laser Surgery means PREMIUM

  • Do you offer premium lenses within your portfolio?
  • Do you want to offer a premium service with a laser option?
  • Do you want to avoid the expensive and time consuming effort with femto laser assisted cataract surgery?

  • The Nano-Laser is easily adapted to your Phaco Ultrasonic system by simply plugging in the cutters tubing.
  • Inexpensive single-use handpieces eliminate the need for cleaning, sterilization and tuning of the phaco handpiece.
  • Complete single-use-sets are available.
  • The Nano-Laser is maintenance free.

Upgrade your Phaco with a laser system as easy as 1-2-3

  • The laser avoids mechanical side effects caused by the oscillating phaco tip – minimum risk for a capsular rupture.
  • Eliminates the risk of cross contamination - Single-use handpieces guarantee highest sterility.
  • LOCS P- and -C criterias can be fulfilled.

No more expensive handpieces.
No more cross contamination.
No more need for a Femto.

Lasers attract patients

With the introduction of Lasik, laser became the number one tool in ophthalmology and patient satisfaction.

  • Patients have never been so highly attracted by any other means of surgery.
  • Patients demand laser surgery - especially in ophthalmology.
  • Lasers are advanced technology and contribute to a high value image of your practice.
  • There is no other treatment with the appeal of laser based surgery.
  • It’s only a small step for you to get started with PREMIUM laser surgery.


The A.R.C. Nano-Laser emulsifies the cataract with pulses that are gentle and effective.

  • No moving parts,
  • no temperature gradient
  • and Cataract-Laser-Surgery is yours upon request.

Inexpensive, single-use, lightweight laser handpieces eliminate the need for cleaning, sterilization and tuning of the heavy phaco handpiece.

Nano-Laser with coaxial handpiece

Coaxial with two different sleeves allows small incisions of 2.2 or 2.6 mm.
Your other hand assists with your manipulator. Coaxial fluid management works the same way as conventional ultrasound phaco.

The Nano-Laser surgery benefits from an extremely little energy into the eye.
