The evolution of diagnostic techniques, including topographers, tomography and detection of changes in corneal biomechanics has changed the early detection of ectasia, because they are a complication of refractive surgery. However, there is still no consensus on the clinical signs that distinguish subclinical, frustrated or suspected ectasia. Currently, not all centers have equipment to evaluate corneal posterior elevation, so an adequate study of the patient must be complemented with clinical and imaging studies. We present a case of a myopic patient who underwent LASIK more than 10 years ago, in Cuba, where the technology and protocols did not include the study of posterior elevation, which illustrates the importance of early detection of ectasia.
