title: LASIK enhancement using excimer laser ablation on the back of the flap.
abstract: OBJECTIVE
  To report our surgical technique for LASIK enhancement by ablating the underside of the flap.
  
  
  METHODS
  Surgical case report of clinical outcomes in three eyes of two patients who had an initial laser ablation in the bed with subsequent enhancements on the underside of the flap.
  
  
  RESULTS
  Following LASIK enhancement on the back of the flap, two eyes gained one line of best spectacle-corrected visual acuity (BSCVA) after treatment compared to preoperatively, going from 20/15 to 20/12, and one eye maintained BSCVA at 20/20.
  
  
  CONCLUSIONS
  Excimer laser ablation of the underside of the flap is a viable alternative to treat corneas with minimal residual tissue whether primary or enhancement procedures are needed. A surgical learning curve exists with this technique.
