Discontinue wearing contact lenses three weeks prior to myopia surgery. Prolonged contact lens wear may alter corneal shape and increase infection risk. Corneal topography is performed to confirm that corneal curvature has returned to its natural state before surgery. If the cornea is too thin, laser surgery may be contraindicated—specifically, if the remaining corneal thickness after ablation of the required refractive correction falls below the safety threshold, alternative surgical options must be considered.
