Summary
Image processing-assisted trabeculotomy (IP-LOT) using the NGENUITY® 3D visual system enhances trabecular mesh work visibility. This method also improves surgeon posture by reducing working distance compared to microscope-assisted trabeculotomy (MS-LOT).
Area of Science:
- Ophthalmology
- Surgical Technology
- Medical Imaging
Background:
- Glaucoma surgery aims to improve aqueous humor outflow.
- Trabeculotomy is a key surgical procedure for glaucoma.
- Improving visualization and surgeon ergonomics is crucial for surgical outcomes.
Purpose of the Study:
- To compare the visibility of the trabecular meshwork and surgeon posture between image-processing-assisted trabeculotomy (IP-LOT) and microscope-assisted trabeculotomy (MS-LOT).
Main Methods:
- IP-LOT was performed on pig and human eyes, analyzing image luminance differences.
- Trabecular meshwork visibility was assessed using ImageJ® software.
- Surgeon posture was evaluated by measuring working distance during both IP-LOT and MS-LOT.
Main Results:
- Image processing significantly enhanced luminance contrast between the trabecular meshwork and cornea in both species (p < 0.05).
- IP-LOT resulted in a significantly shorter working distance compared to MS-LOT (p < 0.05).
Conclusions:
- The NGENUITY® 3D visual system improves trabecular meshwork visibility.
- IP-LOT offers ergonomic benefits for surgeons, reducing the distance to the operative eye.
- This technology holds promise for enhancing glaucoma surgical procedures.
