A strong and growing peer reviewed evidence base now supports the Arclight and training package to be an effective and low-cost alternative to traditional more expensive devices. This research funded by a range of sponsors has led to a number of awards.  It has been conducted in Malawi, Tanzania, Rwanda, India, Pakistan and the United Kingdom by a wide range of academic teams including:​

These research publications have been published in a wide range of specialist ophthalmic journals such as EYE Nature, medical education journals including BMC Medical Education as well as more general journals such as the British Medical Journal.

Review articles

Two major review articles have been published on the Arclight explaining the design concept, target users and broad uses of the device.


Comparative evaluations with traditional devices

​Independent institutions have shown that the Arclight is just as effective as traditional devices for observing fundal reflex (red) abnormalities such as congenital cataract or retinoblastoma. Studies have also shown equivalence when examining for signs of disease of the optic nerve and retina such as glaucoma and diabetic retinopathy. Reports have come from normal healthy volunteers, patients in both clinic and in community ‘field’ settings, as well as simulation eye projects.

Medical Education

Studies have demonstrated that the device is an effective tool to teach direct ophthalmoscopy to medical students and other eye care trainees. The SIMulation tools are highly realistic, and considered more ‘real’ than very expensive traditional kit. As a package it all offers an important means to maintain quality teaching in the COVID era.
