“…In vivo alterations in the structure of the rabbit sclera tissues have been studied using polarization‐sensitive optical coherence tomograph . It was shown that PS OCT images of sclera during laser irradiation clearly visualized a characteristic anisotropic zone with high‐amplitude oscillations of the signal intensity, but part of these oscillations disappeared after irradiation.…”

“…Our scientific group is studying a fundamentally new approach to the correction of refraction, based on the modification of cornea and sclera structure and their mechanical stresses field. The method consists of a combination of orthokeratology with laser radiation that does not damage the integrity of the eye tissue [6,7]. Using a laser helps changing the conformation of collagen molecules located on the periphery of the cornea and in the limb.…”

The existing techniques of laser vision correctionone of the most widespread operationsare based presently on a surgical intervention in cornea tissue. Our science team is engaged in studying of in essence new type of correction based on a modification of structure and the field of mechanical tension of a cornea. In this work, the possibility to use of a speckle interferometry method as a basis for the tracking system of cornea structural changes at thermal influence of a nondestructive laser radiation is considered. Also for a cornea, the polymeric phantom was picked up.

Minimally invasive laser-induced thermotherapy (LITT) presents an alternative method to conventional tumor therapeutically interventions, such as surgery, chemotherapy, radiotherapy or nuclear medicine. Optical tissue characteristics of tumor cells and their heat-induced changes are essential issues for controlling LITT progressions. Therefore, it is indispensable to exactly know the absorption coefficient μ a , the scattering coefficient μ s and the anisotropy factor g as well as their changes under rising temperatures in order to simulate the treatment parameters successfully. Optical parameters of two different cancer model tissues -breast cancer cells species MX1 and colon cancer cells species CX1 -were measured in the spectral range 400 -1100 nm as well as in the temperature range 37 -60• C. The absorption coefficient of both cell species was low throughout the spectral range analyzed, while μ s of both species rose with increasing temperatures. The anisotropy factor g however dropped for both tissues with increasing temperatures. Light scatterings inside tissues proceeded continuously forward for all species tested. It was demonstrated that optical tissue properties undergo significant changes along with the vital status of the cells when the temperature increases.
