Near-infrared operating microscopy (NIOM) enables lightless cataract surgery, potentially improving visual acuity and reducing retinal toxicity. This novel system requires skilled surgeons but shows promise for enhanced surgical outcomes.

Area of Science:

  • Ophthalmology
  • Surgical Technology
  • Medical Imaging

Background:

  • Conventional cataract surgery relies on visible light microscopy.
  • The development of novel imaging techniques is crucial for advancing surgical procedures.
  • Near-infrared (NIR) illumination offers potential advantages in surgical visualization.

Observation:

  • A near-infrared operating microscopy (NIOM) system was developed using NIR wavelengths (850-1300 nm) for illumination.
  • The system comprises an optical filter, stereoscopic camera, head-mounted displays, and a recording system.
  • Cataract surgery was performed in 4 patients using NIOM in one eye and conventional microscopy in the fellow eye.

Findings:

  • The NIOM system provided real-time, 3D visualization with sufficient resolution for all surgical steps.

  • Postoperative visual acuity was superior in eyes operated with NIOM compared to conventional microscopy.
  • Effective use of the NIOM system necessitates advanced surgical proficiency.

    • Implications:

    • Lightless cataract surgery using NIOM may lead to improved immediate postoperative visual acuity.
    • This technique could potentially minimize light-induced retinal toxicity and reduce the need for mydriatic agents.
    • The NIOM system may serve as a valuable educational tool for surgical training.
