Interventions to prevent visual fatigue during robotic surgery.

Area of Science:

• Robotics
• Ophthalmology
• Ergonomics

Background:

• Robotic surgery presents unique visual challenges for surgeons, including digital eye strain and accommodative stress from prolonged display and 3D binocular use.
• Symptoms range from blurred vision and dry eyes to headaches and difficulty refocusing, impacting surgeon performance and comfort.

Purpose of the Study:

• To identify and summarize effective ergonomic and visual interventions for managing digital eye strain and visual fatigue in robotic surgeons.
• To provide actionable strategies for minimizing discomfort and maintaining visual acuity during robotic procedures.

Main Methods:

• Review of existing literature on visual fatigue, digital eye strain, and ergonomic interventions in robotic surgery.
• Identification of common symptoms and contributing factors related to prolonged visual tasks in surgical environments.

Main Results:

• Key interventions include optimizing lighting, screen positioning, and neck posture, alongside taking screen breaks and performing eye exercises.
• Correction of refractive errors, use of lubricating eye drops, and blink training are effective in reducing visual fatigue.
• Addressing vergence-accommodation mismatch through slower camera movements and screen breaks is crucial.

Conclusions:

• Robotic surgeons can significantly minimize visual fatigue and digital eye strain through simple, non-invasive ergonomic and visual interventions.
• Implementing these strategies can enhance surgeon comfort, reduce symptoms, and potentially improve surgical outcomes.
