Retinal phototoxicity.

Phototoxic retinal lesions are a product of advances in operative technology. Use of more powerful light sources in both anterior and posterior segment cases and an increase in surgical complexity requiring longer operative times (especially during ophthalmic training) have rendered photic injury a real danger for all surgeons. Though we enjoy the enhanced view offered by modern light sources, we must also keep in mind the additive, detrimental effect of prolonged light exposure. With increased awareness of this potential hazard, surgeons can take steps to minimize the chance of generating a sight-threatening phototoxic lesion.
