The crystalline is a biconvex, avascular and transparent structure, located between the iris and the vitreous humor, in constant development throughout life. Patients who suffer trauma in the anterior segment of the eye may compromise some zonules, resulting in inclinations or displacements of the lens in relation to their usual location. This article presents the case of a patient seen in the emergency department of the Regional Hospital of São José (SC) with a crystalline dislocation in the vitreous cavity due to blunt trauma who, after four months, migrated to the anterior chamber spontaneously, being submitted to facectomy intra-capsular. Although severe traumas to the eye region cause crystalline's displacement to the vitreous cavity, especially blunt impacts, we did not find in the current literature registries of the association of dislocation of the crystalline lens to the vitreous cavity with subsequent migration to the anterior chamber, inferring that the case reported here was rare. We wish to improve knowledge and contribute to literary bases about crystalline dislocation, spreading singularities about this clinical occurrence.
