Glaucoma treatment laser ablation system TENEO™

Product type
The TENEO™ Excimer Laser Platform is an excimer laser system for corneal refractive surgery, engineered to deliver fast flying‑spot ablations with integrated advanced eye‑tracking and an ergonomic surgical workflow.

Overview
TENEO™ combines a compact footprint with high‑speed laser operation and an advanced multi‑dimensional eye‑tracker. The system supports manifest refraction treatment workflows with dedicated software and a touchscreen interface designed for clinical efficiency.

Key features

• Compact system design to optimize clinical space.
• Multi‑dimensional eye‑tracker operating at 1,740 Hz providing X/Y/Z + torsion and dynamic rotational tracking; iris recognition supported.
• Laser pulse frequency: 500 Hz enabling reduced ablation times (approx. 1.2 s/diopter in standard myopic PROSCAN mode with 6 mm optical zone).
• Flying‑spot treatment mode with 1 mm spot size and truncated Gaussian (soft spot) beam shape.
• Closed‑loop energy delivery with three sensors for pulse energy control; sealed, nitrogen‑flushed beam path.
• Integrated ZEISS FR1‑PRO microscope: motorized 5× magnification changer, 3‑axis, 360° swiveling.
• Integrated slit lamp/projector and automatic pupil centration with manual adjustment.
• 24.1" projected capacitive touch screen (PCT), glove‑compatible; native resolution 1920 × 1200; customizable GUI views.
• Patient bed: swiveling up to 60°, XY ±7 cm, Z 17 cm, ergonomic headrest.

Clinical outcomes and patient experience
Reported real‑world results include high postoperative visual acuity and patient‑reported outcomes:

• Nine months postoperative: 97.8% of eyes ≥ 20/25; 99.7% ≥ 20/40.
• Over 50% of patients achieved 20/16 or better.
• 34.8% of eyes gained ≥ 1 line of CDVA.
• Patient‑reported measures: 99% reported little to no difficulty driving at night; 98% patient satisfaction in LASIK cases performed with TENEO™.
• Reported postoperative improvement in contrast sensitivity.

Clinical ergonomics and workflow
The system is designed to support surgeon ergonomics and efficient patient flow: 360° swiveling microscope, bed that swings out for access, adjustable patient positioning, and a touch‑based GUI to streamline setup and reduce procedural steps.

Media and training resources
Available resources include product videos, surgeon testimonials and outcome‑focused media illustrating system operation, clinical workflow and real‑world results.
