Показано, что комбинированное УФ+ИК-воздействие, когда сначала ИК-лазерный импульс (1440 нм), попадающий в полосу поглощения воды с коэффициентом поглощения около 31 см–1, обезвоживает поверхностный слой роговицы и следующий через ~100 мкс УФ-лазерный импульс (213 нм) удаляет тонкий поверхностный слой (1–3 мкм) коллагена, дает многообещающие результаты. Благодаря контролируемому обезвоживанию поверхности роговицы процесс лазерной абляции комбинированным (213 нм + 1444 нм) излучением обеспечивает лучшую воспроизводимость и более высокую производительность. </p></abstract><trans-abstract xml:lang="en"><p>The laser ablation efficiency of eye cornea for UV (213 nm) and combined IR+UV (213 nm + 1444 nm) ablation treatment in safe conditions, preventing laser coagulation at 1444 nm, was investigated. It is shown that the IR+UV combination, when, at the first stage of cornea treatment, an IR laser pulse at 1444 nm, falling into a water absorption band with an absorption coefficient of about 31 cm–1, dehydrates a superficial corneal layer and at the second stage, in about 100 ms, a UV laser pulse at 213 nm ablates a thin (about 1–3 mm) collagen layer, gives promising results. Due to the controlled dehydration of the corneal surface, the process of 213 nm + 1444 nm laser ablation ensures a better reproducibility and a higher productivity. </p></trans-abstract><kwd-group xml:lang="en"><kwd>cornea</kwd><kwd>ablation</kwd><kwd>Nd:YAG laser</kwd><kwd>absorption</kwd><kwd>threshold</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Femtosecond-pulse laser ablation of human corneas / W.
