title: Long-term results of MyoRing treatment of keratoconus.
abstract: OBJECTIVE
  To study long-term results of MyoRing treatment of keratoconus.
  
  
  METHODS
  Retrospective study of MyoRing implantation into a corneal pocket for keratoconus.
  
  
  RESULTS
  Corneal thickness at the thinnest point remained unchanged, SIM K's, manifest sphere and cylinder were significantly improved at the first follow-up 9 months postoperatively and remained stable until the last follow-up about 5 years after surgery. Uncorrected and corrected distance visual acuity (UDVA, CDVA) were significantly improved at the first follow-up 9 months postoperatively and were further ameliorated until the last follow-up about 5 years after surgery.
  
  
  CONCLUSIONS
  The treatment was safe and effective with continuing improvement of visual acuity during the 5 years after surgery.
