Established

For over 10 years, the NanoLaser has been firmly established as a key player in modern premium cataract surgery.

Thanks to its exceptionally gentle approach and 100% single-use handpieces, this innovative technology is winning over more and more surgeons worldwide.

The number of national and international NanoLaser Centers of Excellence continues to grow – and every year, more than 20,000 patients benefit from this gentle treatment method.

Profitable For You and Your Patients

NanoLaser cataract surgery delivers both medical and economic benefits.

For your patients

the focus is on a particularly gentle cold laser procedure with minimal energy application – a clear advantage for premium treatments.

For you as a surgeon

NanoLaser offers the opportunity to integrate an innovative, forward-looking laser procedure into your treatment portfolio – along with recognition as a NanoLaser Center of Excellence.
With customizable service packages, NanoLaser can be quickly and efficiently amortized.

No hidden costs

Instead of regular maintenance contracts, a simple safety check every 24 months is sufficient – predictable, reliable, and cost-effective.

Gentle

Gentle cataract surgery is primarily defined by its ability to protect the corneal endothelium. In the long term, your patients benefit from preserving these delicate cells.

Studies have shown that postoperative endothelial cell density remains stable, cell hexagonality is maintained, and no cell migration occurs.

This remarkable treatment advantage is made possible by NanoLaser’s minimal and endothelium-safe energy delivery, combined with the atraumatic tip of its lightweight, ergonomic handpiece.

Unlike conventional ultrasound phacoemulsification, the NanoLaser handpiece operates without mechanical movements, preventing any rise in temperature at the tip.

Currently, there is no method of performing cataract surgery with less energy than the NanoLaser offers!

NanoLaser technology, combined with special-function intraocular lenses, marks a quantum leap in premium cataract care.

Prof. Dr. Gangolf Sauder

Charlottenklinik for Ophthalmology

One problem in ophthalmology—as in other tech-driven fields—is the lack of openness to revolutionary innovation.

We should always strive to make surgery better and safer. I chose to do things differently and am very satisfied with that decision.

Prof. Dr. Dr. h.c. Norbert Schrage

Kliniken Köln, Eye Clinic Cologne-Mehrheim

I’ve been using the CETUS for four years now to perform very gentle cataract surgery—without ultrasound.

The procedure fully complements traditional phaco and is a wonderful addition to our clinical portfolio.

Frequently Asked Questions about the NanoLaser

The NanoLaser is one of a kind worldwide. Complete lens fragmentation and removal using laser technology is offered exclusively by the CETUS NanoLaser.

100% Laser – 0% Ultrasound

With this, you offer your patients an innovative procedure:

  • Maximum endothelial protection thanks to ultra-low energy input
  • No heat development, as the NanoLaser operates without mechanical vibration
  • Highest hygiene standards and freshly manufactured materials thanks to 100% single-use handpieces

No, the NanoLaser works in conjunction with your existing phaco machine that features a pneumatic vitrectomy port.

During surgery, the NanoLaser replaces phaco energy with its much gentler laser energy.

The fluidics of your machine connect to the NanoLaser handpiece in the same way they would to a standard ultrasound handpiece.

Irrigation and aspiration ports are compatible with common tubing systems.

The NanoLaser connects via the pneumatic vitrectomy port using a trigger tube.

This trigger tube sends pneumatic impulses to the laser, which then fires a laser pulse with each burst of air.

Since this tube never comes into contact with the patient, it remains attached to the machine.

Irrigation, aspiration, and the cut rate (= NanoLaser pulse frequency) are managed within a dedicated NanoLaser program stored on your phaco machine.

👉 No additional foot pedal is required!

NanoLaser is especially suitable for younger patients undergoing a refractive lens exchange or with relatively soft lenses.

These patients benefit the most from the gentle NanoLaser technique, maintaining a high endothelial cell count and excellent long-term vision.

Of course, older patients benefit too. Even if you need to switch to ultrasound for harder lenses, the overall energy applied to the eye is significantly lower due to reduced phaco time.

The NanoLaser handpiece with the included sleeve is designed for incision sizes between 2.4 mm and 2.5 mm and is easy to insert into the eye.

Some users also operate successfully with incisions ranging from 2.2 mm to 2.7 mm.

NanoLight sets a new milestone in cataract surgery.

Have you ever been able to illuminate the lens and its fragments during surgery?

Now you can.

NanoLight enables exactly that—and can also be retrofitted to existing NanoLaser systems.

Enjoy the benefits of:

  • Visualizing occlusion in real time
  • Efficient energy delivery through targeted laser pulses
  • Reduced microscope illumination, for your patients’ comfort
  • Enhanced depth of field and contrast, helping you stay focused
