Relevance. Secondary keratoectasia is a group of diseases of the cornea characterized by its thinning and protrusion. They can occur after various injuries, inflammatory diseases, surgical interventions and other factors. Early diagnosis and assessment of the severity of secondary keratoectasias are crucial for choosing the optimal treatment tactics and predicting visual functions. A multimodal examination of the anterior segment of the eye allows you to obtain comprehensive information about the condition of the cornea. By combining data from various research methods, it is possible to improve the accuracy of diagnosis and assessment of secondary keratoectasias. The purpose of the study. To evaluate the effectiveness of a multimodal approach to the study of the anterior segment of the eye in secondary keratoectasias that developed after refractive surgery. Materials and methods. The study included 73 patients (110 eyes) with keratoectasias that developed after refractive surgery, from 2012 to 2022. All patients underwent a comprehensive ophthalmological examination, including: visometry, ophthalmoscopy, biomicroscopy. We performed screening of the anterior and posterior surfaces of the cornea using a Pentacam keratotopograph. In addition, we performed optical coherence tomography (OCT) on a Tomey device and endothelial microscopy on an automated Tomey EM 400 contactless microscope. Results and conclusions. The results of keratotopography showed abnormalities in the shape of the cornea, such as asymmetry, irregularity. In OCT, thinning and bulging of the cornea were found, which is typical for secondary keratoectasia. Anomalies in the structure of the endothelium were determined using endothelial microscopy. Based on a comparison of the information content and sensitivity of the techniques, an algorithm of diagnostic measures was developed, including keratotopography (sensitivity 94%), OCT (sensitivity 92.9%) and endothelial microscopy (sensitivity 92%).
