PURPOSE: To report two refractive surgery candidates who demonstrated early corneal topographic findings of pellucid @entity528 . METHODS: Case reports. RESULTS: Two candidate @entity1 for corneal laser surgery were examined. The @entity1 had normal examinations, including normal slit lamp biomicroscopy results and corrected visual acuity that was 20/20 or better in each eye. The corneal topography in one eye of @entity1 I and both eyes of @entity1 2 was characterized by the presence of irregular @entity940 and @entity2687 with a pattern consistent with pellucid @entity528 . Marked asymmetry between the eyes was noted. The inferior @entity267 was thinner than the central @entity735 of each @entity1 . CONCLUSION: @entity1 with early @entity2687 often present as refractive surgery candidates with normal corrected visual acuity and normal pachymetry of the central @entity267 . Corneal topography and regional pachymetry measurements can be used to identify these @entity1 . @entity1 with pellucid @entity528 are not good candidates for refractive surgery because of the potential for poor outcomes and the possibility that iatrogenic thinning of the @entity267 could lead to progression of the disease.
