AAO 2008: Bradley Randleman, MD, Describes A New Ectasia Risk Assessment Model
Dr. J. Bradley Randleman discusses a new risk-score model for assessing post-LASIK ectasia risk in an interview with refractive editor Dr. David Goldman. Five risk factors were identified: 1.) topographic abnormalities, 2.) low residual stromal bed thickness, 3.) young age, 4.) low preoperative corneal thickness, and 5.) myopia. Dr. Randleman then comments on thin-flap, or SBK, in the context of the tensile strength of the various layers of the cornea. In treating ectasia patients, gas permeable contact lenses alone have shown promise. Trials evaluating corneal cross-linking with riboflavin and UVA (Read more...)
