title: Contrast sensitivity in deep anterior lamellar keratoplasty versus penetrating keratoplasty.
abstract: OBJECTIVE
  To compare the measurements of contrast sensitivity at a distance in patients submitted to penetrating keratoplasty versus patients submitted to deep anterior lamellar keratoplasty for keratoconus treatment.
  
  
  METHODS
  Contrast sensitivity of 15 subjects submitted to penetrating keratoplasty and 15 subjects submitted to deep anterior lamellar keratoplasty have been analyzed through the Functional Acuity Contrast Test (F.A.C.T) 301.
  
  
  RESULTS
  There was no statistically significant difference between the measurements for penetrating keratoplasty and deep anterior lamellar keratoplasty.
  
  
  CONCLUSIONS
  Contrast sensitivity was similar among the subjects submitted to penetrating keratoplasty and to deep anterior lamellar keratoplasty for keratoconus treatment.
