  • Abstract
  • Look Inside

We evaluated videokeratoscopic findings in 100 eyes regarding the influence of instantaneous and axial powers on the color-coded map pattern. The series comprised eyes with normal cornea, direct astigmatism, keratoconus, following radial or photorefractive keratotomy and pseudophakia. The findings could be classified into six discrete types by both powers. Videokeratoscopy with instantaneous power showed more localized and definite steepening in keratoconus than axial power. It also enabled detection of high curvature areas between the ablated and nonablated zones in eyes after photorefractive keratotomy. The findings show the necessity to take the power factors into consideration in interpreting color-coded maps in videokeratoscopy.
