A Verisyse phakic intraocular lens (pIOL) (AMO) was implanted in the eye of a 3-year-old child with unilateral high myopia and suspected dense amblyopia. Four years postoperatively, the Snellen visual acuity was 20/30 with a refraction of -1.00 -1.00 x 77 and the endothelial cell density was 3262 cells/mm(2) compared with 3092 cells/mm(2) in the right eye. The Verisyse pIOL may be a treatment option to prevent dense amblyopia in children with highly myopic anisometropia.
