Corneal cross-linking has proven safety and efficacy in arresting the progression of keratoconus. Its use has been extended to resolution of corneal edema. We present a case report and review of literature on the treatment of corneal edema using corneal cross-linking. Corneal cross-linking seems to be an effective method in reducing corneal edema at least as a temporary measure till definitive solution, such as penetrating keratoplasty (PKP) or Descemet's stripping automated endothelial keratoplasty (DASEK) is preformed.

Post-Lasik ectasia is the most feared complication following laser in situ keratomileusis (Lasik), occurring in majority of cases within 1 year of surgery. Furthermore, it is reported many years after surgery. In this case series, we report on late onset ectasia in 11 eyes of nine patients occurring at least 6 years after surgery. Causes and management plan are not discussed here. The aim is to emphasis the late occurrence of this complication.

Collagen corneal cross-linking is an acceptable method for halting the progression of keratoconus and post-Lasik ectasia. The traditional method advocates the removal of epithelium for proper saturation of riboflavin within the stroma. The postoperative complications associated with epithelial removal have necessitated the search for a transepithelial method of riboflavin delivery. Controversies aroused with regard to the effectiveness of this approach. In this article, we review the up- to-date literature on this controversial subject.
