Biomechanics
Elastic
Viscous
The cornea is viscoelastic
Biomechanics & Keratoconus
Keratoconus – underlying biomechanical failure
Penetrating Keratoplasty (PKP)
Deep Anterior Lamellar Keratoplasty (DALK)
End stage management options
Aims
• To determine if corneal biomechanics are closer to normal after corneal transplantation
• To determine the effect of corneal transplantation type on corneal biomechanical properties
