We investigated the use of ultrashort pulsed (femtosecond) laser technology in corneal refractive surgery. When compared to longer pulsewidth nanosecond or picosecond laser pulses, femtosecond laser-tissue interactions are characterized by significan

We evaluated the efficacy, safety, and stability of femtosecond laser intrastromal refractive procedures in ex vivo and in vivo models. When compared with longer pulsewidth nanosecond or picosecond laser pulses, femtosecond laser-tissue interactions

Commercial and Biomedical Applications of Ultrafast Lasers.
We investigated three potential femtosecond laser ophthalmic procedures: intrastromal refractive surgery, transcleral photodisruptive glaucoma surgery and photodisruptive ultrasonic lens surgery. A highly reliable, all-solid-state system was used to

To evaluate transscleral glaucoma surgery techniques using ultrashort pulsed lasers, we attempted to produce photodisruption on the inner surface of the sclera without damaging the overlying tissue. We identified two methods, using pulses centered at

We present experiments indicating that it is possible to ablate the sclera without damage to the overlaying conjunctiva. A femtosecond Nd:glass laser with 8.5-/spl mu/J pulse energy was used to ablate the top layers of sclera when the laser was deliv

Femtosecond lasers emitting in the wavelength range around 1 /spl mu/m are attractive sources for a variety of applications. At 1.06 /spl mu/m, neodymium-doped glass offers both the relatively broad gain bandwidth, which is necessary for femtosecond
