Intrastromal refractive surgery with ultrashort laser pulses: in vivo study on the rabbit eye.

Background: Femtosecond (fs) laser pulses may offer new possibilities in the field of refractive surgery, especially when using the laser as a microkeratome. By induction of nonlinear absorption processes the laser can be used to perform intrastromal cuts. The conventional microkeratome, associated with numerous potential side effects, can possibly be replaced.

Optoacoustic imaging for optimization of laser cyclophotocoagulation.

Optoacoustic imaging was used for ophthalmic imaging, especially of the ciliary body region, which is of interest in the treatment of glaucoma. The different tissue structures below the sclera of porcine and rabbit eyes in vitro could be differentiated up to a depth of more than 1.5 mm.
