Paper Abstract
Photodisruption of femtosecond laser at 1700nm wavelength has been demonstrated
as a potential subsurface surgical method that can be used in trabeculectomy for
glaucoma treatment without causing failure due to scarring at the level of conjunctiva
and underlying tissue [1, 2]. In this study, Fourier domain optical coherence
tomography (FD-OCT) technology is used to demonstrate high speed non-invasive
imaging of high precision photodisruption in human sclera. Photodisruption cavities
of different size in human sclera can reveal itself in its 3D FDOCT image. Transclera
channel cut from back to surface and partial transclera channel are easily identified in
3D OCT image. The whole 3D data set acquired with high speed frequency domain
OCT system permits further quantitative analysis of subsurface phtodisruption
incisions. The preliminary results indicate that high speed frequency domain OCT
system is a good candidate for imaging subsurface photodisruption with femtosecond
laser and its 3D image may provide good guidance during surgical procedures when it
is integrated with laser ablation system.
