Augmented reality and optical navigation assisted orbital surgery: a novel integrated workflow.

Area of Science:

• Ophthalmology
• Medical Imaging
• Surgical Technology

Background:

• Orbital surgery presents challenges due to anatomical proximity, limited space, and cosmetic considerations.
• Advancements in surgical techniques are crucial for progress in this demanding field.
• Novel technologies are needed to overcome existing limitations in orbital surgery.

Purpose of the Study:

• To evaluate the integration of augmented reality (AR) and optical navigation in a unified workflow.
• To assess the utility of this integrated system for interdisciplinary decision-making, feasibility, and intraoperative guidance.
• To explore the potential of AR and optical navigation in improving orbital surgical outcomes.

Main Methods:

• Detailed 3D models were created using automated and manual segmentation of high-resolution contrast-enhanced MRI and CT scans.
• Augmented reality was employed for interdisciplinary preoperative planning and intuitive intraoperative navigation.
• Optical surface matching registration, combined with a Mayfield clamp head holder, facilitated navigation-assisted microsurgery.

Main Results:

• Creating detailed 3D models required combinations of MRI sequences and CT scans, proving time-consuming and staff-intensive.
• Augmented reality provided rapid, intuitive interdisciplinary orientation.
• Intraoperative surface matching registration ensured accurate navigation within the orbital space.

Conclusions:

• The integration of optical navigation and microscope systems streamlines the microsurgical workflow and warrants regular implementation.
• Augmented reality serves as a valuable tool for preoperative interdisciplinary planning and intraoperative orientation.
• The combined approach demonstrates significant potential as an educational tool for orbital surgery training.
