China’s National Medical Products Administration (NMPA) has granted regulatory approval for 2 next-generation ophthalmic surgical microscopes—the ZEISS ARTEVO 750 and ARTEVO 850—expanding the available optical and digital visualization technologies for anterior and posterior segment surgery.¹
According to the NMPA announcement, both devices offer enhanced resolution and illumination systems designed to support microsurgical precision, with expanded digital capabilities on the 850 model. ¹ The approval reflects mounting interest in integrating higher-fidelity visualization, intraoperative optical imaging, and digital workflows into routine ophthalmic surgery.
Surgical microscopes have been central to ophthalmic procedures for decades. Traditional optical microscopes provide binocular stereopsis and magnification critical for delicate maneuvers in cataract and retinal surgery. Advances in digital and heads-up visualization aim to improve ergonomics, reduce surgeon fatigue, and integrate intraoperative imaging—such as microscope-integrated optical coherence tomography (iOCT)—directly into the operative field.²,³
The ZEISS ARTEVO 750 is positioned as a high-resolution optical surgical microscope featuring adjustable RGB LED illumination and a data overlay system (AdVision) integrated into the eyepiece, which can present surgical data and assistive overlays during procedures.⁵ According to manufacturer documentation, the device allows modulation of light color temperature and provides illumination with a high color rendering index, which can aid in tissue visualization and red reflex stability.⁵ A variant of microscope-integrated OCT is also supported, enabling real-time tomographic views of anterior and posterior segment structures.¹
The ARTEVO 850 builds on these features with a fully digital 3-dimensional heads-up display that projects high-resolution surgical images on an external monitor via dual 4K cameras.⁷ Digital Color Assistant (DCA) technology on the 850 is designed to enhance anatomical contrast, and the Smart Depth of Field feature aims to expand the visual depth available without increasing illumination intensity.⁷ Additional workflow integration includes reference image matching and interactive control interfaces linked to ZEISS’s CALLISTO eye platform, which can support intraoperative guidance for tasks like toric intraocular lens alignment.⁷
Key Facts
• Devices: ZEISS ARTEVO 750 and ZEISS ARTEVO 850 ophthalmic surgical microscopes
• Class: Surgical visualization systems with optical and digital imaging capabilities
• Regulatory Action: Approved by China’s National Medical Products Administration ¹
• Clinical Application: Anterior and posterior segment surgery, including cataract, glaucoma, corneal, and vitreoretinal procedures ¹
• Key Features: Enhanced resolution and RGB illumination (750); 3D heads-up display with Digital Color Assistant and Smart Depth of Field (850) ⁵-⁷
• Evidence Base: Limited peer-reviewed clinical outcomes specific to these models; indirect evidence suggests ergonomic and visualization benefits with digital systems
• Considerations: Clinical impact on long-term outcomes and cost-effectiveness not yet established
Clinical and ergonomic advantages of digital visualization systems have been documented in independent studies. Comparisons of 3D visualization systems with conventional optical microscopes in macular surgeries suggest potential benefits, including shorter membrane peeling times and fewer dye injections, as well as reduced intraoperative complications such as retinal hemorrhage.¹-⁶ Similarly, digital visualization systems integrated with iOCT have shown improved visualization of intraoperative imaging streams and may facilitate real-time feedback without needing to switch views.¹
Despite these technological gains, robust clinical outcome data specific to the ZEISS ARTEVO 750 and 850 are limited in peer-reviewed literature. Most published evidence on digital platforms involves prototype systems or comparisons with conventional visualization in small cohorts. Furthermore, while ergonomic improvements and enhanced field visualization are appealing, the impact on long-term visual outcomes, complication rates, and cost-effectiveness requires further investigation.
Clinical Context
Advances in surgical visualization technology align with broader ophthalmic trends, including increasing procedural volumes (notably cataract surgery) and demand for precision in vitreoretinal and minimally invasive glaucoma procedures. Cataracts remain the leading cause of reversible visual impairment globally, and improvements in surgical safety and efficacy are perennial clinical priorities in ophthalmology.⁴ Enhanced visualization systems may support intricate surgical steps, including fine posterior capsule polishing, epiretinal membrane peeling, and shallow-angle glaucoma interventions.
The standard of care for cataract surgery remains microscope-assisted phacoemulsification with intraocular lens implantation under coaxial illumination, relying on the surgeon’s binocular vision through optical oculars. Microscope-integrated iOCT and heads-up 3D visualization are increasingly explored as adjuncts to enhance depth perception, reduce operator fatigue, and integrate digital workflows, but adoption varies by region and practice setting.²
Interpretation and Outlook
The recent NMPA approvals represent a regulatory milestone that could broaden access to advanced visualization technology in China. However, clinicians should interpret device claims cautiously, recognizing that most evidence supporting digital and 3D visualization systems remains observational or derived from small series. Direct comparative trials demonstrating superiority in clinical outcomes over conventional microscopes are sparse.²
Future studies should focus on randomized comparisons, long-term safety outcomes, and standardized measures of surgical efficiency. Adoption will also depend on training, cost considerations, and integration with existing surgical suites. As digital and AI-enabled tools continue to evolve, further research could clarify their role in improving surgical precision and patient outcomes.
