Retinal burns occurring at cataract extraction.

|November 1, 1984
Summary
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.
