Retinopathy of Prematurity Laser: Planning the Equipment

What laser photocoagulation for ROP involves

In retinopathy of prematurity (ROP) the peripheral retina of a preterm infant is incompletely vascularised. When a screening ophthalmologist decides that treatment is indicated, laser photocoagulation of the avascular peripheral retina is one established option; other options exist and the choice belongs to the treating clinicians and the family. This article deals only with equipment.

The procedure is delivered through an indirect ophthalmoscope, usually with a scleral depressor and an eyelid speculum, under sedation or anaesthesia according to the unit's protocol and with continuous infant monitoring.

ROP laser equipment: the usual configuration

The common configuration is a portable diode laser around 810 nm coupled to a head-mounted indirect ophthalmoscope. A.R.C. Laser supplies exactly this pairing: the FOX IV 810 diode laser, 8 W and 1.53 kg, operated from battery or mains, and the LIO, a Neitz indirect ophthalmoscope with laser coupling designed for the FOX 810.

According to the manufacturer, the LIO lets the ophthalmologist move from examination straight to retinal coagulation independently of a slit lamp and is a key tool for treating retinopathy of prematurity. The click-plug connection joins laser and ophthalmoscope quickly, and Clear-View filters protect the user without impairing visibility. For retinal treatments the FOX IV 810 output can be limited to 3 W.

For the technique itself and how it compares with slit-lamp delivery, read our explainer on the laser indirect ophthalmoscope.

Laser photocoagulation for ROP: logistics and the neonatal environment

The infant often cannot be moved safely, so the equipment has to come to the bedside. A battery-capable, portable laser removes the need for a fixed trolley and mains socket close to the incubator. Plan the route from storage to NICU, the placement of the laser relative to monitors and ventilation equipment, and where the fibre will run so it cannot be tripped over.

Ask who will set up the laser and carry out the pre-procedure checks, how fibres and any single-use items are handled according to your infection control policy, and how the device is kept charged and ready between infrequent cases. A unit that is used a few times a month is more likely to fail from neglect than from wear.

• Dedicated, labelled storage with the charger and spare fibre kit.
• Pre-use checklist: self-test, aiming beam, footswitch, filters.
• Agreed role list: ophthalmologist, assistant, neonatologist or anaesthetist, nurse.

Safety in a neonatal unit

The treatment beam is a Class 4 hazard in the room. Define the controlled area, put up signage, and make sure everyone present has suitable eyewear for the wavelength. Oxygen-enriched atmospheres around infants are common in neonatal units, so involve your fire safety and laser safety officers in the plan, and see our guides to medical laser safety and laser safety eyewear.

Record the settings, number of spots and any events for every session. Good documentation supports follow-up and audit.

Questions to ask a supplier

Ask what training and proctoring the supplier offers, how quickly the portable laser can be serviced and calibrated in the UAE, what spare fibres and accessories are stocked locally, and what the warranty covers. Ask for a demonstration at your site, with your headset and your NICU layout, because a smooth setup matters more in neonatal care than a long specification list.

Confirm the registration status of the devices with the competent authorities, since requirements are updated from time to time. Beckfinity can arrange a demonstration of the A.R.C. LIO with the FOX IV 810 and give you a quote tailored to your neonatal or retina service.
