The review assesses physical exercises as an additional non-pharmacological mean of combating the progression of primary open-angle glaucoma. The ophthalmic hypotensive effect is determined by the type of exercise, its duration and intensity. Moderate aerobic activity is preferred. Among dynamic exercises, jogging has the greatest hypotensive effect. Upper body isometric resistance training provides a more lasting decrease in ophthalmotonus. The decrease in intraocular pressure (IOP) in patients with glaucoma is several times more pronounced in comparison with healthy people and occurs regardless of the nature of the local drug antihypertensive therapy. After the termination of classes IOP returns to the previous level on average within a month. An increase in ocular perfusion pressure associated with physical activity dictates the appropriateness of physical exercise for patients with pseudo-normal pressure glaucoma. The combination of hypotensive, vascular, neuroprotective effects of physical activity with a high level of physical fi tness does not exclude a decrease in the risk of development and progression of primary open-angle glaucoma. The development of indications for the use of physical activity by patients with advanced glaucoma, including those who have undergone hypotensive surgery, remains relevant. The type, intensity, dosage and mode of performing the recommended physical exercises require an individual choice.

Comparison of preoperative pachymetry with intraoperative pachymetry; evaluation of the features of intraoperative pachymetry during surgery, practical application. Material and methods. The analysis of the results of 58 operations for myopia by the FemtoLASIK method was carried out. Femtosecond laser is a Ziemer femtosecond laser. Refractive ablation – with a SCHWIND Amaris 750 S excimer laser with integrated OCP. Pachymetry was performed in the center of the cornea at the diagnostic stage and during the operation: before the formation of the flap, after the formation and removal of the flap, and after the completion of ablation. Results. It was statistically reliably revealed that intraoperative pachymetry during FemtoLASIK differs from the planned one. The regularity is associated with the process of hydration of the corneal stroma during vacuum fixation of a femtosecond laser and with the process of dehydration during laser ablation. Conclusion. The obtained results allow us to speak about step-by-step control of the corneal thickness during FemtoLASIK and comparison of the planned parameters with those measured during the operation, as a way to timely detect deviations from the operation plan and, as a result, reduce the risk of pathological corneal thinning. In cases where the values of the corneal thickness in the central zone before the operation and the flap thickness correspond to the preoperative plan, the discrepancy between the planned RST indicator and its actual measured value during the operation is not critical. Key words: FemtoLASIK, intraoperative pachymetry, residual thickness of the stromal bed, hydration, corneal dehydration.
