title: A standardized drawing scheme to document corneal changes following refractive corneal surgery.
abstract: OBJECTIVE
  To present a systematic and standardized drawing scheme for unambiguous and reproducible documentation of corneal changes after incisional techniques, coagulative procedures, and lamellar and surface ablation excimer surgery.
  
  
  METHODS
  Standardized symbols in five colors representing specific corneal conditions after incisional surgery (eg, radial keratotomy, astigmatic keratotomy), coagulative procedures (eg, laser thermokeratoplasty, conductive keratoplasty), surface ablation (eg, photorefractive keratectomy, laser subepithelial keratomileusis, epi-LASIK), and LASIK are used to record corneal changes in frontal and sectional views.
  
  
  RESULTS
  Corneal changes following refractive corneal surgery were documented.
  
  
  CONCLUSIONS
  The drawing scheme permits specific features to be followed in the clinic in a clear and unambiguous manner.
