Tight Sutures

Tight sutures after penetrating keratoplasty

Clinical Features

  • Symptoms: usually asymptomatic.
  • Tight sutures in one or multiple areas immediately after penetrating keratoplasty is not an uncommon finding.
  • Although they may induce irregular astigmatism, the corneal curvature will change over time during the healing process.


  • Suture replacement is very rarely if at all never been indicated.
  • Routine follow up and careful graft evaluation is the mainstay of management.
