Surgical management of crystalline lens dislocation into the anterior chamber with corneal touch and secondary glaucoma

Abstract

We present a 53-year-old man with a crystalline lens that spontaneously dislocated anteriorly with corneal touch and secondary glaucoma. A dry anterior vitrectomy and partial intercapsular lensectomy were performed using a limbal approach to control intraocular pressure (IOP) and decrease the lens volume. The lens capsule was gently separated from the corneal endothelium with viscoelastic material, after which a bimanual lensectomy was performed with a vitrectomy probe and a phacoemulsification microflow tip. The risk for expulsive choroidal hemorrhage, which can occur during large-incision, open-chamber surgery; a sudden IOP decrease; and significant damage to the corneal endothelium were avoided with this technique. After secondary intraocular lens scleral fixation, the final visual acuity was 20/25.
