Abstract
An apparatus for ophthalmic procedures contains a source of aiming and treatment laser beams, folded mirrors and lens arrays to cause the formation of a static pupil on a delivery mirror for observation and treatment by an operator of the apparatus.
Claims26
A device comprising:
- a treatment laser source;
- one or more scanning mirrors downstream in an optical path of a laser beam from the treatment laser source, the scanning mirrors producing an astigmatic pupil from the laser beam of the treatment laser source;
- one or more lens systems downstream from and in the optical path of a laser beam from the scanning mirrors;
- the one or more lens systems adjusting the light beam from the scanning mirrors such that a light beam from the one or more lens systems converges as a pupil on a delivery mirror;
- the one or more lens systems converting the astigmatic pupil to a non-astigmatic pupil;
- wherein the one or more lens systems form a static pupil on the delivery mirror which is independent of any movement, position or pattern defined by the one or more scanning mirrors.
