Abstract
Purpose. The analysis of the advantages and disadvantages of existing optical methods for correcting postkeratoplastic ametropia (PA). Material and methods. When studying the literature review on PA correction, a search was carried out for sources in the PubMed and Scopus abstract databases for the period up to 2021 inclusive. In total, 50 articles related to the topic of the review were selected, including long-term observations on the methods of optical correction of PA that are currently used worldwide. Results. Today, in addition to spectacle and contact correction, there is a large selection of various methods of surgical correction of PA: wedge resection, various options for keratotomy, implantation of toric intraocular lenses, phakic toric lenses, refractive laser surgery – photorefractive keratectomy, laser in situkeratomileusis, ReLEx SMILE technology, and also implantation of intrastromal corneal segments. The choice of the most optimal optical method for PA correction, depending on the initial individual clinical and functional parameters of the patient, remains quite relevant today. This is due both to a large number of different methods of PA correction, each of which has its own advantages and disadvantages, which necessitates their improvement, and to the need to develop new techniques. Conclusion. Currently, there are a large number of various methods for correcting postkeratoplastic ametropia, each of which has its own advantages and disadvantages. It is necessary to develop a systematic approach to the personalized choice of an optical method for correcting postkeratoplastic ametropia, taking into account its effectiveness and safety, depending on the individual clinical and functional data of the patient. There is a need for the development of new methods of correction that would effectively and safely correct high values of postkeratoplastic ametropia, especially with an asymmetric type of keratotopogram. Key words: postkeratoplastic ametropia, femtosecond laser, corneal segments, scleral contact lenses
