Intraoperative OCT - Cataract Surgery (iOCT) , Case series

Summary

The video discusses the use of Intraoperative Optical Coherence Tomography (iOCT) in Cataract Surgery, highlighting its applications and benefits in real-time surgical management. Key points include:

Scientific Concepts and Discoveries

• Intraoperative Optical Coherence Tomography (iOCT): A technology that provides real-time imaging during Cataract Surgery, enhancing the surgeon's ability to assess and manage various surgical challenges.
• Applications in Ophthalmic Surgery: iOCT has been successfully applied in corneal and vitreoretinal surgeries, including:
  • Lamellar keratoplasty
  • Internal limiting membrane (ILM) peeling
  • Macular Hole Surgery

Methodology and Case Insights

• Assessment of Surgical Techniques:
  • Evaluation of corneal incisions (length, breadth, and planes) in real-time.
  • Visualization of cavitation or gaps between corneal surfaces before manual opening.
  • Assessment of sclerotic anterior lens capsule and identification of adhesions.
• Challenges in Surgery:
  • Managing posterior polar cataracts with intact capsules, ensuring safe phacoemulsification.
  • Addressing traumatic cataracts with zonal dialysis, confirming intraocular lens (IOL) centration and stability.
• Iris Hook Placement: Techniques for achieving proper pupil size and positioning during surgery.
• Complicated Cases: Use of iOCT to assess remnant cortex and ensure complete removal during re-surgery.
• Filament Loop Technique: Visualization of a microthin self-expanding nitinol filament for nucleus fragmentation.

Limitations of iOCT

Issues such as shadowing from surgical instruments and lack of eye tracking systems.

Conclusion

iOCT is presented as an emerging technology with the potential to significantly improve surgical techniques and patient outcomes in Cataract Surgery.
