This paper reviews and makes a critical analysis of radiofrequency in ophthalmology. Localized heating of the cornea has been apllied since 1889 for different therapeutic and surgical objectives.The principle that heating corneal tissue causes shrinking of the collagen that changes the corneal curvature. After the approval of FDA in 2004, we initiated a multicenter study in Brazil coordinated by ABC School of Medicine that resulted in an analyses of 258 patients. Inconclusion the study showed that the procedure had a temporary result and the best results were obtained in patients between 45 and 55 years old without optical correction for far.We believe that the problem has not been solved yet and a great deal of research effort should be focused.
