What are the new findings?
We highlight the need for purpose-built, head-mounted displays tailored to the specific demands of ophthalmic surgery.
Our paper demonstrates the potential of using head-mounted displays in ophthalmic microsurgery.
How might it impact on healthcare in the future?
The widespread implementation of these devices will help alleviate musculoskeletal pain commonly seen in ophthalmologists who operate with traditional microscope.
Digital visualisation devices will allow for enhanced visualisation of the surgical field and digital overlays not attainable with a traditional analogue visualisation.
We demonstrate a collaborative iterative device design approach between clinician users and device manufacturers.
Surgical microscopes are necessary for the performance of a majority of ophthalmic procedures. However, the use of traditional microscopes often leads to abnormal body positioning, musculoskeletal pain and fatigue.1–3 Furthermore, pain in the back, neck and shoulder is disproportionately reported among ophthalmologists as compared with other medical specialties. The resulting injuries sustained may lead to chronic pain and decreased career longevity.4 Increasing use of three-dimensional (3D) heads-up display (HUD) monitors has been reported for both anterior and posterior segment ophthalmic procedures, as well as in several other surgical fields.1 HUD implies visualisation through a digital 3D display panel rather than through a traditional operating microscope.5 These systems, such as the TrueVision 3D Visualization System (TrueVision Systems, Santa Barbara, California, USA), use glasses with polarised lenses in conjunction with a consumer 3D monitor to create a stereoscopic image.6 7 Several use cases for image overlays have been explored, including image-guided toric intraocular lens positioning during cataract surgery and intraoperative ocular coherence tomography for posterior segment procedures.1 8 HUDs have been reported to decrease surgeon fatigue by allowing ergonomic body posturing without compromising visualisation, technical difficulty, surgical time, visual outcomes or complication rates.5 9 10 Additional benefits of moving from optical to digital visualisation include high-resolution digital zoom, increased depth of …
