Summary
Xenon light phototoxicity can cause retinal alterations after combined cataract and epiretinal membrane surgery. Surgeons should manage light settings to prevent these visual complications.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Cataract Surgery
Background:
- Combined cataract and epiretinal membrane surgery is a common procedure.
- Phacoemulsification and posterior vitrectomy are standard surgical techniques.
Observation:
- Two female patients developed mottled hypo- and hyperpigmented retinal alterations post-surgery.
- These alterations were diagnosed as Xenon light-induced phototoxicity lesions.
Findings:
- Key factors contributing to these lesions include light power, exposure duration, wavelength, and endoilluminator-retina distance.
- While the fovea offers some protection, these factors must be controlled.
Implications:
- Awareness of these factors is crucial for preventing iatrogenic retinal damage.
- Optimizing light parameters during surgery can mitigate the risk of phototoxicity.
- This case report highlights the importance of careful light management in ophthalmic surgery.
