The femtosecond laser

The femtosecond laser is today the most advanced instrumentation for the corneal and cataract surgery. The term “femtosecond” derives from the duration of each laser pulse, which is of the order of an infinitesimal fraction of a second.

Clinical applications

The applications of femtosecond laser eye surgery include:

1) Laser correction of refractive defects, or femto-LASIK. The femtosecond laser has its main application in laser surgery to correct myopia, hyperopia and astigmatism. The creation of the corneal flap in LASIK with femtosecond laser is now one of the most advanced refractive surgery techniques.

2) The penetrating keratoplasty, or full-thickness corneal transplant. Thanks to the use of the femtosecond laser, the surgeon can personalize the edges’ shape of the donor cornea and make them to coincide exactly with those of the host, thus minimizing the postoperative astigmatism and improving the visual performance of each patient.

3) The lamellar keratoplasty techniques, such as deep anterior keratoplasty and endothelial keratoplasty. The laser system allows the surgeon to cut the corneal tissue to the desired depth, with micrometric accuracy, thus allowing the improvement of the surgical outcome.

4) Astigmatic keratotomy. The laser system allows precise correction of irregular residue after penetrating keratoplasty due to the creation of arcuate incisions in the donor tissue in order to improve vision.

5) Intrastromal rings. The intrastromal rings are materials used for the reduction of irregular astigmatism. The laser system allows you to create intrastromal pockets with absolute precision and speed, while minimizing surgical trauma to the corneal tissue.

6) Cataract surgery: the femtosecond laser is used to create the corneal incisions, capsulorhexis and fragmentation of cataract.

Our Results

The Staff of Vision Engineering srl Italy is regularly taking part in the improvement of laser techniques for endothelial keratoplasty, femto-LASIK and cataract surgery. The results of the research activities of our staff are regularly published in major scientific journals.
