    This video asserts that Scheimpflug corneal tomography provides the most advanced and accurate method for screening ectasia risk prior to laser vision correction. Some of the possible reasons include objective and validated parameters, which have been shown in many clinical studies. Considering that keratectasia occurs due to a combination of preoperative predisposition or susceptibility of the patient's cornea and the impact from surgery on corneal structure, future screening approaches for detecting ectasia risk need to consider a combination of patient-related data and procedure-related parameters.
