    Operating microscope light can cause paramacular changes during cataract surgery, even with safety measures. This complication, affecting both pseudophakes and nonpseudophakes, persists despite current protective strategies.

    Area of Science:

    • Ophthalmology
    • Surgical Complications
    • Retinal Imaging

    Background:

    • Previous reports documented paramacular changes from operating microscope light after cataract surgery.
    • These changes were observed in patients undergoing extracapsular cataract extraction with posterior chamber lens implantation.

    Purpose of the Study:

    • To report on additional cases of paramacular changes potentially induced by operating microscope light.
    • To evaluate the occurrence of these burns in a broader patient population, including pseudophakes and nonpseudophakes.

    Main Methods:

    • The study reports on twelve additional patients with macular and paramacular burns.
    • Data included patient status (pseudophakes/nonpseudophakes), visual outcomes, and light source details (tungsten bulb or halogen/fiberoptic).

  • Preoperative angiography was assessed in three cases.

    • Main Results:

    • Paramacular and macular burns were observed in the reported patients.
    • Burns occurred despite the use of filters and light barriers in some instances.
    • Visual loss ranged from none to severe.

    Conclusions:

    • Recommended safety measures for operating microscope light have not eliminated the complication of paramacular burns.
    • The findings highlight the persistent risk of light-induced retinal damage during cataract surgery.
