title: Vitreous hemorrhage following phakic anterior chamber intraocular lens implantation in severe myopia.
abstract: OBJECTIVE
  To describe two cases of vitreous hemorrhage following phakic anterior chamber lens (AC-IOL) implantation in high myopia.
  
  
  METHODS
  In case 1, hemorrhage developed one month after surgery, without retinal involvement, and visual acuity (VA) resulted 20/200 after pars-plana vitrectomy (PPV). In Case 2, vitreous hemorrhage was complicated by retinal detachment (RD). PPV and silicone oil injection were performed, with AC-IOL removal and cristalline lens extraction. After 2 years the retina was attached and VA was 20/80.
  
  
  CONCLUSIONS
  Only few cases of RD, posterior uveitis and endophthalmitis are reported following phakic AC-IOL implant. Vitreous hemorrhage could represent an additional posterior segment complication. Intraoperative manoeuvres, hypotony-induced posterior vitreous detachment and/or peripheral retina traction could play a role in engendering this complication in highly myopic eyes.
