Чаще всего этиологическим фактором является грамположительная бактериальная флора, вызывающая типичное формирование «кристаллов» в передних слоях стромы роговицы. Реже инфильтраты формируются грам-отрицательной бактериальной флорой, для которой характерно расположение преимущественно в задних отделах стромы. К нетипичным этиологическим агентам относятся микобактерии и грибковая микрофлора. Основными предрасполагающими факторами развития ИКК являются медикаментозная иммуносупрессия и предшествующая хирургическая операция на роговице (сквозная кератопластика, послойная кератопластика, лазерный кератомилез in situ — LASIK). В данной статье описан нетипичный клинический случай монолатеральной послеоперационной инфекционной кристаллической кератопатии. В анамнезе заболевания пациента — билатеральная операция LASIK с последующей медикаментозной терапией послеоперационного кератита правого глаза на протяжении 1 месяца.</p></abstract><trans-abstract xml:lang="en"><p>Infectious crystalline keratopathy (ICK) is a sluggish infectious inflammation of the cornea. Described for the first time in 1983, it is currently a rare pathology. Most often, the etiological factor is gram-positive bacterial flora, which causes the typical formation of “crystals” in the anterior layers of the corneal stroma. Less often, infiltrates are formed by gram-negative bacterial flora, which is characterized by its location mainly in the posterior parts of the stroma. Atypical etiological agents include Mycobacteria and fungal microflora. The main predisposing factors for the development of ICK are drug immunosuppression and previous corneal surgery (through keratoplasty, layered keratoplasty, laser keratomilesis in situ — LASIK). This article describes an atypical clinical case of monolateral postoperative infectious crystalline keratopathy. The patient’s medical history includes bilateral LASIK surgery followed by drug therapy for postoperative keratitis of the right eye for 1 month.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>инфекционная кристаллическая кератопатия</kwd><kwd>кератит</kwd><kwd>LASIK</kwd></kwd-group><kwd-group xml:lang="en"><kwd>infectious crystalline keratopathy</kwd><kwd>keratitis</kwd><kwd>LASIK</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">Porter AJ, Lee GA, Jun AS.
