| Device |
ophthalmic femtosecond laser |
| Definition |
Precise cutting or ablation of ocular tissue, indicated for the anterior capsulotomy during cataract surgery. |
| Physical State |
The device consists of a laser console, a computer with grahic user interface, a beam delivery system that positions and focuses the laser beam, and a patient interface system that flattens the cornea and holds the patient's eye still during the surgical procedure. |
| Technical Method |
A Nd:glass solid state laser generates sub-picosecond pulses at a 15 kHz repetition rate. The beam is focused at high convergence to a spot diameter <6 microns at the target location. Tissue is vaporized in a very small region at the focal point. A computer-controlled 3-dimensional scanning system positions the beam with micron-scale accuracy. |
| Target Area |
Anterior lens capsule of the eye. |
