refractive surgical problem
Unfortunately, the preoperative pachymetry is not known. The Orbscan images show a posterior corneal bulge in both eyes, more evident in right. Moreover, the anterior topographies and elevation maps show prolate corneas, not oblate such as after LASIK for myopia.
The clinical and topographical images suggest an iatrogenic keratectasia in both eyes. Therefore, if the patient has difficulty tolerating RGP lenses and has severe symptoms, I recommend surgical treatment. If the endothelial pattern is good, lamellar keratoplasty could be useful; however, PKP is the best option.© 2001 by Lippincott Williams & Wilkins, Inc.
