Haag-Streit Simulation releases Eyesi Indirect ROP Laser Module

New release for the Eyesi Indirect ROP Simulator teaches residents how to master demanding laser therapy skills, creating a complete training solution for ROP diagnosis, classification, and treatment.

From today, ophthalmology and medical schools have a new weapon in their training armoury: a simulator that teaches residents not only how to screen for ROP, but to apply effective treatments.

What is ROP?

Retinopathy of Prematurity (ROP) is a disease of the eye that affects blood vessels in the retina. Following a premature birth, these vessels may begin to grow abnormally – which left untreated, can lead to partial or total sight loss. The first step for all babies at risk of developing ROP is the screening examination: a process that involves examining the retina using a using an indirect ophthalmoscope, a speculum, and a scleral indentor.

First step – screening

The examination is recognized to be highly challenging, particularly for the resident doctor. Since 2024, Haag-Streit Simulation has provided a complete simulator training system for examining, and classifying, ROP. Today, the Eyesi Indirect ROP Simulator is used by training institutions around the world to help ophthalmologists build competence and confidence in the challenging ROP examination in a lifelike, yet risk-free, environment.

Next step – treatment

Peripheral laser photocoagulation (“laser therapy”) targets abnormal blood vessel growth by placing laser burns in the affected retinal area. Similarly to ROP screening, it’s a demanding procedure that isn’t only tricky to learn – it’s very time-consuming for experts to teach. Through the release of our new module, trainees can now learn all the skills required not only to diagnose, but treat, ROP.

Realistic laser setup

Carrying out laser therapy is a complex task involving the simultaneous alignment and manipulation of multiple instruments. With the help of the laser tasks, trainees learn how to “fire” the laser accurately. Using the touchscreen, users are guided through the different laser settings, and learn how to optimize parameters such as power, pulse duration, and intervals to deliver just the right level of power.

Laser therapy courseware

The new laser therapy courseware starts with exercises on focusing and aiming the laser foot beam. This is followed by courses to help users laser in the periphery, choosing the correct laser settings (duration and power), and using the laser in pulsed mode with an optimal interval between shots. 

Optimum position of laser spots

Mirroring real-life scenarios, trainees learn how to treat ROP – beginning with smaller areas, as well as the complete retina. During the training, users learn to master the optimum number and position of laser burns – too close together, and the retina can be damaged; too far apart, then the VEGF signal molecule is still produced in the untreated area, and the abnormal blood vessel growth continues.

Assessment of treated area

After the simulated treatment, trainees receive a comprehensive, objective evaluation of the treated area and are appraised on their laser application versus various assessment criteria. Evaluated parameters are, for example, the delivered laser energy, the number of shots, and the completeness of the defined treatment area.

New online medical course

A new online medical course complements the practical simulator courses, offering essential background information on types of lasers and their settings, optimal placement, and color of laser spots, as well as patient preparation and laser application techniques. Additionally, trainees will receive an overview of alternative pharmacologic and surgical treatment options.
