Corneal ectasia is a serious vision-threatening complication of laser in situ keratomileusis (LASIK). In many ways it is similar to the naturally occurring Keratoconus and managed in the same way. It is associated with progressive corneal steepening, an increase in myopia and astigmatism, and decrease in uncorrected visual acuity. Severe cases can be managed with lamellar or penetrating keratoplasty; however, minimally invasive techniques are also possible. These options include medication to reduce intraocular pressure (IOP), rigid gas-permeable contact lenses, intrastromal corneal ring segments (ICRSs or Intacs), and corneal crosslinking with ultraviolet radiation and riboflavin treatment.
