摘要：
An ophthalmic surgical apparatus includes: a laser source emitting a beam of one picosecond to one nanosecond pulses； an optical system focusing the beam on a focal point； and a system for moving the focal point along a predetermined path. The laser source generates the beam, focused next to a surface of the anterior segment of the eye, the focal point located at a distance from an optical axis of symmetry of the anterior segment of the eye. The system for moving the beam includes a single degree of freedom of rotation about an axis of rotation to move the focal point along a curved path located in an annular area about the optical axis of symmetry of the anterior segment of the eye. The ophthalmic surgical apparatus has a numerical aperture limiting the geometric optical aberrations at the focal point and on the entire curved path.
