Erbium is a lanthanoid rare earth element often used as a dopant in fiber optic laser amplifiers for optical communications. Erbium:YAG lasers have been considered for use in phacoemulsification, vitrectomy and trabecular ablation procedures in laser eye surgery Erbium was named after the town of Ytterby, Sweden, which also gave rise to the names of terbium, ytterbium, and yttrium.
