The Metaverse in Ophthalmology: Application and Perceived Benefits, Challenges, Realistic Expectations, and Future Outlook.

Abstract

Purpose: To explore the potential of the metaverse, a three-dimensional platform merging physical and virtual realities (VRs), in advancing the field of ophthalmology. This study examines its applications in areas such as VR-based surgical training, augmented reality (AR)-assisted surgeries, artificial intelligence (AI)-driven diagnostics, and teleophthalmology. This review builds upon previous literature by integrating recent evidence and technological advancements, offering a more comprehensive analysis of particular applications and barriers in ophthalmology.

Methods: Academic literature published between 2019 and 2024 was identified through searches in the PubMed database and Google Scholar search engine using relevant keywords. This review focused on studies discussing the application of the metaverse in health care and ophthalmology, with particular attention to key trends, emerging uses, technological features, and associated challenges.

Results: A total of 60 studies were deemed relevant for inclusion in this review. The infrastructure supporting the Metaverse comprises technologies such as the Internet of Things, digital twins, mirror worlds, nonfungible tokens, blockchain technology, and lifelogging. Together, these technologies create immersive environments that users can access through VR headsets, AR glasses, and handheld controllers. The metaverse presents promising opportunities in ophthalmology, particularly in enhancing clinical training through simulators such as the EyeSi™ surgical simulator, VRmagic EyeSi Slit Lamp, and the HelpMeSee™ VR simulator. In addition, it facilitates remote consultations and improves diagnostic and treatment options, exemplified by tools such as the Vivid Vision™ system for amblyopia, the Microsoft HoloLens™ for navigating complex anatomical structures, and AI-based platforms for the early detection of diseases such as glaucoma and diabetic retinopathy. Furthermore, the metaverse may enhance patient education by simulating the visual effects of ophthalmic conditions and visualizing postoperative outcomes. However, challenges, including financial limitations, data security concerns, and cultural acceptance, must be addressed.

Conclusions: A gradual and context-specific integration of the metaverse is essential, particularly in underdeveloped regions. As the metaverse evolves, it holds significant potential to transform the field of ophthalmology by promoting global collaboration and innovation, complementing traditional practices, and ensuring equitable access to advanced healthcare solutions.
