3D visualization system and standard operating microscope for ease of visualization and surgeon comfort during...

Area of Science:

• Ophthalmology
• Surgical Technology
• Medical Imaging

Background:

• Phacoemulsification is a common cataract surgery technique.
• Visualization systems significantly impact surgical performance and surgeon ergonomics.
• Evaluating new technologies like the NGENUITY® 3D system is crucial for advancing surgical practice.

Purpose of the Study:

• To compare the ease of visualization and surgeon comfort between the NGENUITY® 3D (NG) visualization system and the standard operating microscope (SOM).
• To assess the impact of these visualization modalities on surgeon ergonomics during phacoemulsification.

Main Methods:

• A prospective, randomized, single-blind, single-center study involving 224 phacoemulsification surgeries.
• Surgeons were randomly assigned to either the NG or SOM group.
• Surgeon comfort and visualization ease were evaluated using a 27-parameter Surgeon Comfort Score questionnaire.

Main Results:

• Ease of visualization and hand-eye coordination scores were comparable between the NG and SOM groups.
• Postoperative neck discomfort was numerically lower in the NG group (1.04) compared to the SOM group (1.56).
• The NG system enabled safe phacoemulsification with lower surgical field illumination.

Conclusions:

• The NGENUITY® 3D system offers comparable visualization ease to the standard operating microscope for phacoemulsification.
• The NG system may lead to reduced postoperative neck discomfort and allows for lower illumination settings.
• Further research could explore long-term ergonomic benefits and patient outcomes.
