This article clearly demonstrates that patients with milder disease, an average keratometry reading of less than 53 D, do better than patients with more advanced disease.

Cornea 2006; 25:29-33. This article illustrates the potential for a high complication rate in patients with advanced disease and who are treated with the mechanical spreader.

This article for the first time describes the use of the femtosecond laser to create the channels for inserting Intacs and demonstrates that it is a superior procedure over the insertion of Intacs with a mechanical spreader.
