Therefore, treatment options focusing on anterior corneal surface provide satisfactory results and are particularly successful in eyes with irregular corneas. Topography-guided ablations offer promising outcomes for the treatment of corneal irregularities that developed after laser-assisted in-situ keratomileusis (LASIK) interface and flap issues, penetrating keratoplasty, radial keratotomy, and other extremely irregular corneas that are mostly inappropriate for wavefront-guided ablations. Recently, the structural irregularities and refractive errors in ectatic corneal diseases have been treated with the combination of topography-guided ablation and corneal cross-linking (CXL). This combined therapy has provided encouraging results. Keywords : Topography-guided ablation, excimer laser, irregular cornea, corneal ectasia
