title: [Implantation of the molteno tube for refractory glaucoma following penetrating keratoplasty].
abstract: OBJECTIVE
  To assess the surgical effectiveness of the molteno tube implantation in glaucoma secondary to penetrating keratoplasty.
  
  
  METHODS
  9 eyes in critical condition with glaucoma secondary to corneal graft surgery, whose intraocular pressures (IOP) have previously failed to respond to glaucoma medication, were undergone Molteno tube implantation.
  
  
  RESULTS
  IOPs ranged from 0.8-2.8 kPa (1 kPa = 7.5 mmHg) were obtained in 7 eyes, the success rate accounted for 7/9, 2 eyes still required installation of beta-blocker, the graft rejection occurred in one eye and was remedied with medical treatment, the graft remained half-transparent in one eye. Visual acuity improved in 4 eyes, stayed the same in 4 eyes and was worse in one eye. The best corrected visual acuity over 0.05 was recorded in 4 eyes.
  
  
  CONCLUSIONS
  Moltemo tube implantation is a rational and effective method for preserving a certain level of visual acuity in patients with glaucoma following penetrating keratoplasty.
