[Corneal topography of patients with unsatisfactory visual acuity after epikeratophakia for aphakia].

Corneal topographic characteristics of 5 patients who obtained unsatisfactory vision after aphakic epikeratophakia, with at least nine months follow-up, were reported. All grafts were apparently decentered relative to visual axis. The contour of cornea showed highly irregular pattern of power distribution. These findings suggest that to mark visual axis before surgery, lathe corneal lenses carefully and do standard operation should be the basis of successful epikeratophakia.
