This lecture-format review presents a summary of methods for assessing the condition of corneal nerve fibers (CNF), their clinical significance, and an overview of their anatomy and physiology. It briefly analyzes the structural and functional characteristics of CNF in various ocular diseases, following eye surgeries, and in patients with systemic diseases accompanied by systemic polyneuropathy. The article describes in detail the management algorithm that involves a comprehensive analysis of CNF and Langerhans inflammatory cells, identifies the at-risk groups for developing structural nerve impairments, and outlines the main criteria for CNF assessment.

Unlabelled: The scientific and practical interest in studying the biomechanical characteristics of the lens capsule, on the one hand, is associated with its anatomical significance in modern microinvasive phaco surgery, and on the other hand, with investigation of the mechanisms of lens curvature changes during accommodation. Selective study of the biomechanical properties of the lens capsule aims to identify characteristics of various regions and surfaces of the capsule.
Purpose: This study is a comparative analysis of age-related changes in the biomechanical properties of the anterior (AC) and posterior (PC) lens capsules in humans.

Article Synopsis
- Heavy eye syndrome (HES) is a unique type of strabismus caused by a significant elongation of the eye's axial length, leading to misalignment and reduced eye movement, often seen in patients with high myopia.
- Identification of HES relies on multislice computed tomography (MSCT), which reveals a key sign of the condition: the dislocation of the posterior pole from the muscle cone.
- The preferred surgical option for HES involves techniques that reposition the superior and lateral rectus muscles, as traditional surgeries are less effective and may complicate future treatment.
Unlabelled: The introduction of bidirectional corneal applanation technologies into clinical practice made possible the in vivo assessment of biomechanical properties of the fibrous tunic in myopic eyes.
Purpose: This study analyzes the potential of bidirectional corneal applanation with high-speed video recording for biomechanical control of myopia, focusing on the biomechanical parameters of the sclera and cornea.
Material And Methods: The study included 129 patients (168 eyes) with myopia ranging from -0.
Article Synopsis
- The study explores the accuracy of different methods for measuring regular astigmatism parameters, which is essential for effective optical correction, particularly with toric intraocular lenses.
- Based on a group of 83 patients, the research reveals a significant discrepancy in diagnostic results between automatic refractometry and subjective tests, especially for against-the-rule astigmatism.
- The findings indicate that misaligned cylinder axes significantly affect visual acuity, with greater declines observed when the axis deviates by 10-15 degrees, particularly in with-the-rule astigmatism.
