by Prof. Michael W. Belin
A 46-year-old female had undergone LASIK 2 years prior. She was interested in further vision
enhancement for her dominant right eye. Her best spectacle corrected visual acuity (BSCVA) was
20/20+ with sph -1.25 D.
The referring surgeon was concerned about post LASIK ectasia based on an Orbscan® topography
showing significant posterior elevation (Figure 34).
