OCT‑guided surgery uses intraoperative optical coherence tomography imaging to visualise ocular tissues in real time during operations. It provides cross‑sectional views that help surgeons judge tissue planes and completeness of manoeuvres.
How It Is Used
In retinal and corneal surgery, microscope‑integrated OCT can show residual membranes, fluid, or graft apposition while the procedure is underway. Surgeons can adjust techniques immediately based on this feedback.
- Particularly valuable in macular surgery, lamellar keratoplasty, and glaucoma procedures
- Reduces reliance on subjective visual cues alone
- May decrease the need for re‑operations by confirming results intraoperatively
- Images can be stored for teaching and documentation
Benefits and Limitations
OCT guidance enhances precision but adds equipment cost and learning curves. Image quality can be affected by instruments or media opacity.
- Workflow integration is improving with newer microscope‑integrated systems
- Real‑time interpretation skills develop with experience
- Technology complements, rather than replaces, surgical judgement
- Further advances may combine OCT with robotic or navigated surgery
