В рамках ограниченного, проспективного, моноцентрового пилотного исследования было прооперировано 2 пациента (2 глаза) мужского пола в возрасте 60 и 55 лет. Давность выполнения радиальных насечек составила 34 и 38 лет. Показанием к операции явились прогрессирующая биомеханическая нестабильность роговицы и функциональные рефракционно-визуальные флюктуации. В течение 12 месяцев после операции оценивались осложнения, корригируемая острота зрения, кератометрические показатели, биомикроскопическая прозрачность роговицы, удовлетворенность пациента.Результаты. В период наблюдения осложнений не отмечено, роговица и трансплантат сохранили прозрачность. Средняя толщина трансплантата БС составила 20±2,1 мкм. Средняя корригируемая контактными линзами острота зрения увеличилась с 0,4±0,3 до 0,65±0,1, средний показатель кератометрического астигматизма изменился с 1,9±1,6 до 3,0 дптр, данные показатели сохранялись в 6, 9 и 12 месяцев, что свидетельствует о достижении биомеханической стабильности роговицы, отсутствии рефракционно-визуальных флюктуаций.Заключение. При поздних осложнениях РК трансплантация БС позволяет частично восстановить нормальную анатомию передней поверхности роговицы и обеспечивает ее биомеханическую стабильность в 12-ти месячный период наблюдения. Для максимально объективных выводов необходимо увеличить число клинических случаев и сроки наблюдения. </p></abstract><trans-abstract xml:lang="en"><p>Late complications of radial keratotomy (RK), are as a rule caused by a change in the biomechanical properties of the cornea.</p><sec><title>Purpose</title><p>Purpose: to study the long-term stabilizing effect of the Bowman’s layer (BL) transplantation after RK.</p></sec><sec><title>Material and methods</title><p>Material and methods. In a limited, prospective, monocentric pilot study we operated 2 male patients (2 eyes) aged 60 and 55. The radial incisions had been performed 34 and 38 years ago. The indications for surgery were progressive biomechanical instability of the cornea and functional refractive visual fluctuations. Within 12 months after the operation, complications, corrected visual acuity, keratometric parameters, biomicroscopic transparency of the cornea, and patient satisfaction were assessed.</p></sec><sec><title>Results</title><p>Results. No complications were noted during the follow-up period, the cornea and graft retained transparency. The average thickness of the BS graft was 20±2.1 µm. The average visual acuity corrected by contact lenses increased from 0.4±0.3 to 0.65±0.1, the average indicator of keratometric astigmatism changed from 1.9±1.6 to 3.0 D, these indicators remained after 6, 9 and 12 months, which indicates that biomechanical stability of the cornea was achieved and that the refractive-visual fluctuations are absent.</p></sec><sec><title>Conclusion</title><p>Conclusion. In late term RK complications, BS transplantation partially restores the normal anatomy of the anterior surface of the cornea and ensures its biomechanical stability during a 12-month follow-up period. For the conclusions to be maximally objective, more clinical cases should be studied within a longer observation period.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>трансплантация боуменового слоя</kwd><kwd>эксимерлазерная абляция</kwd><kwd>послойная кератопластика</kwd><kwd>радиальная кератотомия</kwd><kwd>кератэктазия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Bowman’s layer transplantation</kwd><kwd>corneal transplantation</kwd><kwd>excimer laser ablation</kwd><kwd>lamellar keratoplasty</kwd><kwd>radial keratotomy</kwd><kwd>keratectasia</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">Schiotz H.
