Post keratoplasty dimensional and refractive change in contact lens and spectacle corrected cases.

ABSTRACT

Two groups of patients who had corneal transplantations for keratoconus were analysed retrospectively. One group had been visually corrected with corneal contact lenses and the second group had worn spectacles or used no optical correction. The reduction in post graft corneal astigmatism with time following removal of sutures was examined by the method of regression in groups. The results showed that the reduction in corneal astigmatism was significantly greater in the contact lens wearing group.
