The present invention relates to a femtosecond laser ophthalmological system and especially to the use of a femtosecond laser to create a flap for LASIK refractive surgery or for other applications that require removal of corneal or lens tissue at specific locations such as in corneal transplants, stromal tunnels, corneal lenticular extraction and cataract surgery. The output of a femtosecond laser is scanned into overlapping circles of laser pulses which are then moved in an overlapping trajectory on a patients eye to ablate the eye tissue in a predetermined pattern.
