Hexagonal keratotomy is a historic refractive surgical technique in which six linear incisions are made into the stroma of the peripheral cornea in a hexagonal pattern that encircles the central cornea in an attempt to correct hyperopia. This patient had also previously had radial and astigmatic keratotomy surgery in this eye with resultant corneal scars outside of the hexagonal keratotomy pattern in radial and transverse orientations.
