Although currently laser surgery is a very popular tool for various vision disorders correction, it is still difficult to ensure proper control over the accuracy, efficiency and safety of such procedures. Therefore, Russian scientists proposed a new method that helps to describe tissue changes after such operations. This method was described in a series of publications in the Journal of Biophotonics, Journal of Biomedical Optics and Laser Physics Letters.

For the widespread and safe clinical use of lasers for eye surgeries, it is crucial to ensure high-precision control of the given shape of the fabric and its stability. At the same time, it is important to evaluate the accompanying changes in the tissue microstructure and its mechanical properties after laser modification. One of the most promising methods for such applications is optical coherence tomography (OCT). OCT occupies a niche between medical ultrasound and optical microscopy as it can visualize the tissue structure by infrared light scattering, with a resolution of up to several micrones.

Russian researchers implemented OCT to investigate tissue deformations and mechanical properties changes. The study was conducted on samples of collagen tissue such as rabbit cornea and pig cartilage that were subjected to the procedures of localized thermomechanical modification by laser.

“We place the cornea or cartilage sample under investigation between two silicone layers with a known stiffness. Visualizing with the help of OCT the mechanically produced deformations in such a construction, it is possible to quantitatively map the distribution of the elastic modulus of the tissue under investigation, both before and after laser thermomechanical modification,” says Vladimir Zaytsev, Doctor of physical and mathematical sciences, Head of the laboratory of wave methods for studying structural- Heterogeneous media IAP RAS.

The results are in good agreement with the data obtained by various methods of microscopy and in theoretical computer simulations. However, optical coherent elastography does not require special preparation of the drug using dehydration, staining and other destructive procedures. The developed non-invasive elastographic approach can be used in medicine for the quick assessment of the long-term stability of cartilage implants prepared by laser reshaping, as well as for monitoring the procedures of thermomechanical cornea modification and various diagnostic studies.

“Preliminary results make it possible to count on the promise of using OCT-elastography to perform” optical biopsy “of tumor diseases, and not just to distinguish between tissue in the normal state and pathology,” concludes Vladimir Zaitsev.
