A system to treat a patient comprises a user interface that allows a physician to view an image of tissue to be treated in order to develop a treatment plan to resect tissue with a predefined removal profile. The image may comprise a plurality of images, and the planned treatment is shown on the images. The treatment probe may comprise an anchor, and the image shown on the screen may have a reference image marker shown on the screen corresponding to the anchor. The planned tissue removal profile can be displayed and scaled to the image of the target tissue of an organ such as the prostate, and the physician can adjust the treatment profile based on the scaled images to provide a treatment profile in three dimensions. The images shown on the display may comprise segmented images of the patient with treatment plan overlaid on the images.

A system and apparatus for increasing the amplitude of accommodation and/or changing the refractive power and/or enabling the removal of the clear or cataractous lens material of a natural crystalline lens is provided. Generally, the system comprises a laser, optics for delivering the laser beam and a control system for delivering the laser beam to the lens in a particular pattern. There is further provided a range determining system for determining the shape and position of the lens with respect to the laser. There is yet further provided a method and system for delivering a laser beam in the lens of the eye in a predetermined shot pattern.

The invention provides systems and methods for the removal of diseased cells during surgery.

A method for fractional tissue treatment includes using a first energy source to heat a skin treatment zone to a sub-necrotic temperature level, and using a second energy source to apply fractional energy to the skin treatment zone to create a matrix of ablation and/or coagulation micro-zones.

An aesthetic laser apparatus for performing treatment by irradiating a human skin to be treated by a variable pulsed laser beam is disclosed. This apparatus includes a laser source which emits variable waveform output of treatment laser beam pulses; a flexible beam delivery for delivering the treatment laser beam emitted from the laser source, the flexible beam delivery includes at the distal end automated optical scanner comprising of 2 moving mirrors; and a surgical instrument is connected to an end of the scanner and used for irradiating the treatment laser beam delivered therein to the treatment human skin. By having the ability to vary the laser's output pulse frequency, pulse width, and pulse energy, multiple tissue effects can be achieved using one laser surgical apparatus.

According to some embodiments, a system for fractionally treating tissue includes: an electromagnetic radiation (EMR) source configured to generate an EMR beam having a transverse ring energy profile; an optic configured to converge the EMR beam to a focal region located within a tissue; and, a window assembly located down-beam from the optic configured to cool the tissue when placed in contact with an outer surface of the tissue.
