Fully integrated 577nm yellow laser combining Lumibird Medical exclusive fiber laser technology with SingleSpot, Multispot Pattern Scanning and Subliminal® treatment modes.

Easyret® features a unique, clinically oriented user interface and software-guided treatment procedures facilitating the implementation of the laser spots and enhancing retinal treatments. 

Key Features

  • Most versatile wavelength with best chromophore absorption profile.
  • Perfectly homogenous laser spot profile ensuring even laser treatments.
  • Multispot Pattern Scanning mode for peripheral treatments is better tolerated by patients.
  • SubLiminal® subthreshold mode for tissue sparing macular treatments.

3 reasons to choose Easyret®

577nm Yellow laser wavelength

Presented as the most versatile wavelength in scientific literature, the 577nm wavelength offers the following benefits:

  • Excellent combined absorption by both melanin and oxyhemoglobin (peak absorption of oxyhemoglobin) [1,2]
  • Very little absorption by macular xanthophyll pigments [1,2]
  • Excellent penetration through cataracts and hazy media [1,2]

Multispot Pattern Scanning treatment mode

Characterized by the use of short pulse durations from 10 to 20 ms, the Multispot Pattern Scanning treatment mode offers many advantages over classical treatments:

  • Less heat diffusion to the retina and choroid, less damage to the retinal nerve fiber layer [3,4]
  • Comfortable treatment better tolerated by patients [5]
  • Treatment time reduction (full PRP in 1 session) [6]

The Multispot Pattern Scanning treatment mode can be delivered through 4 customizable patterns for better adaptation to the treatment site.

Single spot - Squares - Circles - Triple arcs

SubLiminal treatment mode

Composed of a train of extremely short microsecond pulses, this subthreshold treatment mode (non-visible laser impacts) is a tissue sparing treatment mode avoiding scarring [7,8] while treating Diabetic Macular Edema [7] and Central Serous Chorioretinopathy [8].
