To provide a comprehensive overview of ectasia development following laser-assisted in situ keratomileusis (LASIK).

Materials and methods

Literature review of relevant studies dealing with corneal ectasia associated with refractive surgery, keratoconus (KC), and cross-linking.


Post Laser-assisted (PLE) involves histopathologic, clinical, and topographic characteristics similar to KC. Several risk screening indices were developed to enhance the detection of KC suspect and mild KC cases prior to the laser procedure. A grading system of PLE was developed, based on risk factors for the severity of ectasia, primarily measured by visual loss. The aims of the treatment are halting ectasia progression and restoring visual acuity.


Familiarity with the highly sensitive and specific indices for ectasia screening, in addition to procedure parameters that increase the likelihood of ectasia development following the refractive procedure, is essential for minimizing the risk of PLE. However, when ectasia develops, early recognition and proper management are essential to prevent progression and improve visual rehabilitation.
