Astigmatism laser excision null

摘要

(57) Abstract Laser surface excision manner and the device which the re-border form the surface astigmatism are disclosed. Optical system (10) for forming the elliptic laser lighting pattern (30) in the target surface, cylindrical refraction forma optical system (18) is included. By the continual change of the field of elliptic lighting, excision profile of astigmatism dual refraction die is implemented. As for this invention, ekishimareza cornea formation, it is desirable to be used for ekishimareza and simultaneous cornea curvature formation or other excision ophthalmology operation for.
