Astigmatic laser ablation of surfaces |
| abstract |
(57) Summary A laser ablation method and apparatus for astigmatically recontouring a surface is disclosed. The optical system (10) includes a cylindrical refractive optical system (18) for forming an elliptical laser irradiation pattern (30) on the target surface. An astigmatic birefringent ablation profile is achieved by the continuous variation of the area of the elliptical illumination. The present invention is preferably used with an excimer laser for excimer laser keratoplasty, corneal curvature surgery or other ablative ophthalmic surgery. |
