Case Report
Abstract

Purpose: To report 3 cases of keratoconic patients who had progressive corneal topographic flattening during a 2-year follow-up period.

Methods: Case series.

Results: Three patients with bilateral keratoconus, each operated for advanced keratoconus in one of their eyes, were observed for possible progression of the disorder for a period of 2 years. During the 2-year follow-up period, topographic examination showed progressive corneal flattening in the nonoperated eye. Mean keratometry decreased in all patients, whereas topography showed significant flattening at the apex of the cone. Best-spectacle-corrected visual acuity increased in one of the patients, whereas the others had stable uncorrected and best-spectacle-corrected visual acuity during the follow-up period. All patients had positive family medical history for diabetes mellitus, but none of them was diabetic.

Conclusions: This is the first report of topography-based keratoconus regression during a 2-year follow-up period.
