Summary
Intraoperative optical coherence tomography (iOCT) improves visibility during Descemet membrane endothelial keratoplasty (DMEK). This technology enhances graft handling and safety, offering better surgical control and potentially reducing procedure times.
Area of Science:
- Ophthalmology
- Surgical Technology
- Medical Imaging
Background:
- Descemet membrane endothelial keratoplasty (DMEK) presents visibility challenges due to the en face view.
- Enhanced intraoperative overview is crucial for surgeon control during DMEK.
Purpose of the Study:
- To retrospectively analyze the utility of intraoperative optical coherence tomography (iOCT) in enhancing DMEK safety.
- To evaluate iOCT's impact on surgical visibility and procedure efficiency.
Main Methods:
- Retrospective analysis of imaging and video data from 26 eyes undergoing DMEK with iOCT.
- Evaluation of surgical step visualization, procedure duration, and anterior chamber air-filling time.
Main Results:
- iOCT enabled visualization of all DMEK surgical steps.
- Mean DMEK procedure duration was 25.7 minutes with iOCT.
- Mean intraoperative air-filling time was significantly reduced with iOCT.
Conclusions:
- Intraoperative OCT significantly improves graft visibility and handling during DMEK.
- iOCT enhances the safety and efficiency of Descemet membrane endothelial keratoplasty.
- iOCT is a valuable tool supporting surgeons throughout DMEK procedures.
