An electro-mechanical-type handpiece is specially designed to be used with a laser Generator, particularly those that use a CO.sub.2 laser and provide a laser beam in fractional mode. The fractional mode laser beam is provided in a pattern of homogeneous points aligned in rows, columns or diagonally, and such a pattern allows internal tissue along an entire length of a vagina of a patient to be treated and a pelvic floor of the patient to be retracted, such that a urinary bladder of the patient is elevated and, owing to the change in angle thereof, slight or moderate losses of urine are resolved or improved. In addition, the device can be used to treat the inner surface of the vagina of the patient, reducing vaginal laxity caused by childbirth and age.

An ophthalmic surgical laser system and method for forming a lenticule in a subject's eye using fast-scan-slow-sweep scanning scheme. A high frequency scanner forms a fast scanline, which is placed tangential to a parallel of latitude of the surface of the lenticule and then moved in a slow sweep trajectory along a meridian of longitude of the surface of the lenticule in one sweep. Multiple sweeps are performed along different meridians to form the entire lenticule surface, with the orientation of the scanline rotated between successive sweeps. To reduce acceleration and jerk in the XY stage motion, especially during transition from one sweep to the next, the sweeping speed profile is a sigmoid function.

The present invention relates to a single and/or dual laser delivery system attached to an existing ophthalmic operating microscope, comprising of a single and/or dual wavelength laser unit [1]; and a delivery system [5].
