The exoscope, a new tool for endoscopic dacryocystorhinostomy (e-DCR), shows comparable symptom resolution and surgery times to traditional methods. This technology was well-received by surgical teams and offers teaching benefits.
Area of Science:
- Ophthalmology
- Surgical Technology
Background:
- Endoscopic dacryocystorhinostomy (e-DCR) is a standard procedure for lacrimal sac and duct conditions.
- Investigating novel tools to enhance e-DCR procedures is crucial for improving patient outcomes.
Purpose of the Study:
- To evaluate the exoscope as an assistive tool in endoscopic dacryocystorhinostomy (e-DCR).
- To compare the efficacy and safety of exoscope-assisted e-DCR with conventional techniques.
Main Methods:
- The study assessed symptom resolution (epiphora, dacryocystitis) and surgical time as primary endpoints.
- A questionnaire evaluated the surgical team's perception of the exoscope's qualitative features and usability.
Main Results:
- Exoscope-assisted e-DCR demonstrated comparable outcomes in symptom resolution and surgical duration to classic e-DCR.
- The technology was universally accepted by the surgical team, indicating high user satisfaction.
Conclusions:
- The exoscope is a viable new tool that can support endoscopic dacryocystorhinostomy.
- This technology presents significant potential for surgical training and education in ophthalmology.
