In ophthalmology today, laser photodisruptors are used besides laser photocoagulators. Photocoagulators transform light energy into heat energy, causing microcauterisation of tissue. Photodisruptors act non-thermally by controlled cutting of the unwanted tissue, causing microexplosions. The most frequently used photodisruptors are Neodymium YAG, Holmium YAG and Erbium YAG lasers. They differ by type of the active crystal. The laser beam of these lasers is highly coherent, low-divergent, which enables it a high precision. It is used as a microscalpel to cut optical membranes and tissues. |
