Topography-Guided Photorefractive Keratectomy in the Treatment of Corneal Scarring

Corneal scarring can substantially impair visual acuity, either directly, via opacification of the visual axis, by altering corneal optics through stromal remodeling or by induction of significant irregularity of the corneal surface, which may manifest as regular and irregular astigmatism.1 Management of corneal scars and the induced corneal irregularity can be challenging. Treatment options may include: rigid gas-permeable or scleral contact lenses, superficial keratectomy, phototherapeutic keratectomy (PTK), photorefractive keratectomy (PRK), or keratoplasty (either lamellar or
