Kind Code: A1 The present invention provides a custom-made, short-term ablation capability that can treat corneal abnormalities by ablating the refraction therapy profile in a laterally offset manner. These treatment profiles, when centered on the eye E, may be suitable for treating standard refractive errors such as myopia, hyperopia and cylindrical astigmatism. By selectively offsetting one or more ablation profiles at selected points across the corneal surface C, the laser system 14 allows the irregular astigmatism, quadrant corneal gradient, asymmetric astigmatism, previously applied refractive treatment ( (E.g., corneal incision, extracentral resection, asymmetric distortion due to corneal transplantation, keratoplasty in all layers, etc.), abnormal corneal growth, sporadic, bilateral keratoconus, etc. Refraction errors caused by corneal abnormalities such as sex astigmatism and irregularities can be reduced. |
