Retinal Laser Simulation

R.E.A.L.
Eye Model

Practice retinal laser before treating a patient.

The R.E.A.L. Eye Model: a translucent 3D-printed model eye mounted in a black two-axis gimbal orbit housing.

The Reusable Eye for Application of Laser is a reusable retinal laser simulation system for hands-on slit-lamp and laser indirect ophthalmoscopy training.

Reusable  ·  532-nm laser compatible  ·  Slit-lamp + LIO training

A simulator designed around the way retinal laser is actually performed.

Built for ophthalmic laser training.

An eye printed from the schematic eye.

Five components. One reusable eye.

The R.E.A.L. Eye Model disassembled: orbit housing with two-axis gimbal ring, thermochromic retinal cup, and anterior globe with optical lens.

  • Reusable thermochromic retina. Produces visible laser spots that fade as the retinal surface resets.
  • Clinical laser compatible. Designed for retinal photocoagulation training using clinical 532-nm laser systems.
  • Slit-lamp + LIO training. Practice both slit-lamp laser and laser indirect ophthalmoscopy techniques.
  • Scleral depression. Flexible anatomy allows simulation of peripheral treatment with scleral depression.

Train with the same workflow used clinically.

Slit-Lamp Laser

Practice PRP and laser retinopexy with the same workflow used in clinical training.

Laser Indirect Ophthalmoscopy

Practice peripheral retinal treatment and scleral depression before performing the procedure on a patient.

Fundus view during treatment: discrete yellow laser spots visible on the retinal surface.
During — visible spots
Fundus view after treatment: the laser spots have faded back toward baseline.
After — reset

Research

Built from a real training need.

Residents often perform their first retinal laser on a patient. Existing simulators are limited and can be cost-prohibitive. R.E.A.L. was developed by ophthalmologists to make repeated, realistic laser practice accessible.
