Purpose
• Evaluate wavefront measurement in patients
after penetrating keratoplasty(PK) and
correlate it with refraction and corneal
topography
Methods
• 29 patients (35 eyes) who underwent PK betweenJuly 1992 and April 2003
• Mean follow-up: 57.9 months (range 12 to 142)
• UCVA, BCVA, manifest refraction, cycloplegicrefraction, corneal topography and wavefrontanalysis
