Corneal ectasia is a potentially serious complication that can occur after photorefractive keratotomy and laser-assisted in situ keratomileusis in eyes with risk factors such as inferior topographical steepening, as well as in eyes without risk factors. Better identification of forme fruste keratoconus and atypical corneas and more restraint with laser-assisted in situ keratomileusis parameters will reduce this window of corneas at risk. As we develop better technology and outcome-based evaluation criteria for preoperative screening using existing technology, we may be able to reduce the incidence of ectasia through better patient selection.
