Abstract

Thermo-mechanical effect of laser radiation is a basis of new method of normalization of intraocular pressure in glaucomatous eyes due to laser-assisted pore formation in eye sclera. Laser-induced creation of pores in sclera increases hydraulic permeability. Stability of laser-induced pore system is achieved via gas nano-bubbles arisen in the sclera under laser radiation as a result of temperature dependency of gas solubility. The stabilization of laser-induced gas and pore systems in the tissue is an important mechanism for a long lasting healing of glaucoma observed in clinical trials with one year follow-up.
