### Summary box #### What are the new findings? #### How might it impact on healthcare in the future? 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 …

眼科显微手术专用头戴式3D显示器：手术技能表现和评估：初步研究

###摘要框####有哪些新发现？####将来对医疗保健有何影响？对于大多数眼科手术而言，手术显微镜是必不可少的。然而，传统显微镜的使用通常会导致身体定位异常，肌肉骨骼疼痛和疲劳。1–3此外，与其他医学专科相比，眼科医生中背部，颈部和肩部的疼痛报告比例不成比例。由此造成的伤害可能导致慢性疼痛并降低职业寿命。4据报道，前，后段眼科手术以及其他几种手术中，越来越多地使用三维（3D）平视显示器（HUD）监视器外科领域。
