A rare case of unilateral erythropsia, or red-tinted vision, occurred 18 years post-cataract surgery. This visual disturbance was linked to an intraocular lens (IOL) lacking ultraviolet (UV) light protection.

Area of Science:

  • Ophthalmology
  • Visual Neuroscience
  • Medical Optics

Background:

  • Cataract extraction with intraocular lens (IOL) implantation is a common procedure.
  • Intraocular lenses can vary in their properties, including UV light filtration.
  • Long-term complications after IOL implantation are infrequent but important to document.

Observation:

  • A patient presented with unilateral erythropsia (red-tinted vision) lasting one week.
  • The onset of symptoms occurred 18 years after cataract surgery.
  • The affected eye contained an IOL without ultraviolet (UV) light protection.

Findings:

  • The patient's unaffected eye had an IOL with UV light protection.
  • The erythropsia was isolated to the eye with the non-UV-protected IOL.

  • This suggests a potential link between UV exposure and delayed-onset visual disturbances after cataract surgery.

    • Implications:

    • This case highlights the potential long-term impact of IOL material properties on visual function.
    • It underscores the importance of UV protection in intraocular lenses to prevent delayed visual side effects.
    • Further research may be warranted to understand the mechanisms of UV-induced erythropsia in pseudophakic eyes.
