The authors describe a technique involving preoperative swelling of thin corneas (less than 400 microns) to a stromal thickness of at least 400 microns using hypoosmolar riboflavin solution so that corneal collagen crosslinking (CXL) can be performed. Current protocol requires a minimum corneal thickness of 400 microns. This technique could potentially broaden the spectrum of indications for this procedure, including advanced keratoconus with very thin corneas. The authors also present results from a case series of 20 patients in which they observed no complications.
