Retinal photocoagulation laser Selecta® Trio™

trabeculoplastycataract surgeryophthalmic

Overview
The Lumenis Selecta® Trio™ is a compact ophthalmic multi‑modality laser platform integrating retinal, cataract and advanced glaucoma therapies (YAG, SLT and photocoagulation) in a single unit. Its integrated optical design and advanced laser cavity provide flexible delivery with a reduced footprint for clinic and hospital environments.

Product Benefits

• Homogeneous Laser Beam
  Advanced optics and laser delivery produce uniform energy distribution across the spot for precise, consistent photodisruption and photocoagulation while minimizing hot‑spot formation.
• Dual Fiber Port — Instant switching between delivery devices
  Automatic sensing of connected delivery devices and internal parameter adjustment ensure maintained power density at the target when switching instruments.
• ClearView™ Filters — Optimized surgical view
  Photopic‑balanced coating reduces color distortion and improves white light transmission. Built‑in Physician Eye Safety Filter protects against YAG and photocoagulation wavelengths.
• AcuGuide™ Micromanipulator
  Provides accurate beam guidance for fine targeting during procedures.
• Integrated LaserLink Cradle
  Secure storage for the laser adapter when photocoagulation is not in use.

Additional Features

• Storage Space
  Compact built‑in compartment for lenses and accessories.
• Ergonomic Joystick with EZGrip™ Coating
  Joystick with integrated laser fire switch for intuitive control.
• Advanced Adjustable Offset
  Three posterior defocus positions with adjustable focal point up to 350 µm posterior to the aiming beam.
• Magnification Changer
  Full slit lamp capability with 6‑step magnification changer.
• Electronic Height Adjustment
  Table height adjustable via electronic up/down switch for operator ergonomics.
