Refracting the corneal graft.
Patients who have undergone penetrating keratoplasty have unique postoperative refractive requirements. These include irregular astigmatism, high corneal toricity, and anisometropia. We present a stepwise clinical approach for accurate, efficient refraction of these patients, utilizing visual acuity measurement, retinoscopy, subjective refraction, keratometry, photokeratoscopy, and diagnostic rigid contact lens application.
