Consider age, residual stromal bed, percent tissue altered to improve accuracy of screening for ectasia risk
LAS VEGAS — Using the weighted equation of age, residual stromal bed and percent tissue altered may improve the efficacy of screening ectasia risk in patients with normal topography who undergo LASIK, according to a study presented here. “The purpose of this study was to specifically develop an ectasia risk equation considering percent tissue altered, flap percentage, residual stromal bed, ablation depth, and age all together to have a combination that would provide very high sensitivity, and with the other parameters, we would increase the specificity of our findings,” Marcony (Read more...)
