Imaging of the lens capsule with an ultrahigh-resolution spectral optical coherence tomography prototype based on a femtosecond laser
Aim
To demonstrate the applicability of ultrahigh-speed, ultrahigh-resolution spectral optical coherence tomography (SOCT) to cross-sectional imaging of the capsular bag in vivo.
Methods
The ultrahigh-speed and ultrahigh-resolution SOCT prototype was designed and constructed at Nicolaus Copernicus University (Torun, Poland). To obtain an ultrahigh speed up to 100 000 lines/s a new spectrometer with fast CMOS line-scan camera was built. A femtosecond laser with a central wavelength of 780 nm and =160 nm enabled imaging with an axial resolution of 2.3 µm and lateral resolution of 10 µm in tissue. Lens capsules of two healthy eyes were examined with ...
