Learn to laser infants without risk

Focusing & aiming

Course A1: Posterior focus & aiming

In this course, trainees learn how to position the hand-held lens and the head-mounted laser indirect ophthalmoscope (LIO) to achieve a focused laser beam on the posterior avascular retina. They determine the optimal distance between the lens and the ophthalmoscope for laser application. Trainees must find laser targets on the posterior retina, aim at each target, and precisely place a single-pulse laser burn inside.

Lasering in the periphery

Course A2: Peripheral focus & aiming

As in the previous course, trainees must identify a set of laser targets on the infant’s retina. In this course, the targets are smaller and located in the periphery, near the ora serrata, making the task more challenging. While using the scleral depressor to fixate and indent the eye, users practice holding the lens with a calm and steady hand while simultaneously placing accurate laser spots in hard-to-reach areas.

Interval lasering

Course A3: Focus & interval aiming

Course A3 continues with laser targets on the avascular retina. Instead of triggering single laser pulses with the foot pedal, trainees now use the laser in interval pulsing mode. The laser generates repeating laser pulses, which leads to a more time-efficient treatment, but also adds time pressure to the task. Trainees can try out different interval times by adjusting this setting on the Laser tab.

Using the right amount of power

Course B: Laser power training

Using the by-now familiar laser targets, trainees practice setting the correct laser power and pulse duration by assessing the appearance of the laser burns they place. Laser burns should ideally have a grey color, indicating optimal laser settings. Further, trainees learn that the required laser settings depend on various conditions, such as the patient’s individual retinal sensitivity, the current retina area, the laser focus, or the working distance.

Confluent laser spots

Course C: confluence

Now that trainees can place precise laser spots with the correct settings, this course offers tasks that require users to place confluent laser spots in small, confined areas, such as narrow stripes or larger rectangular regions. Confluent means that the burns are placed close together or slightly overlap one another. This course prepares for the final course, where full laser treatments must be performed.

Full laser therapy

Course D: Clinical training

This course contains a variety of virtual clinical ROP cases with different stages and grades of severity. Laser therapy is required in one or both eyes. Trainees must now demonstrate the skills acquired in previous courses in a realistic setting. Laser therapy is applied to the complete avascular retina area up to the ora serrata. Users have to pay attention to the laser spot color and confluency.
