The Er:YAG laser (λ=2.94μm) is an effective tool in vitreo-retinal surgery. Pulsed mid-infrared (λ=6.45μm) radiation from the Free Electron Laser has been touted as a potentially superior cutting tool. To date, use of this laser has been limited

Our previous studies using rabbits and monkeys showed that the Amide II wavelength (6.45 micrometers ) produced by the FEL could efficiently produce an optic nerve sheath fenestration with minimal damage. In order to determine if the technology safel

One glaucoma challenge is the treatment of leaking trabeculectomy blebs. Simple methods such as patching, autologous blood injection, compression sutures or cyanoacrylate glue application often fail. Because the conjunctiva is thin and ischemic, it o

The Free Electron Laser (FEL) at Vanderbilt University is tunable from 2 μm to 9 μm in the mid-infrared spectrum, which is capable of controlling predicted laser-tissue interaction by selecting a specific wavelength. However, delivery of this laser
