decentered ablation correction

Decentered ablation is when the area reshaped by the laser in P RK , LA SEK , La sik , Ep i-Lasik , and other laser assisted refractive surgery techniques is not centered to the eye's visual axis . This often means the edge of the ablation zone is within the visual axis, producing ghosting , starbursts , and/or halos . It is possible that an enhancement will correct the decentered ablation, but that process may increase refractive error and make you o ve
