Laser technologies of corneal surgery perfection was one of the important events in ophthalmology in the past decades. Despite to the significant success in refractive surgery and the achieved high result in visual acuity, the ideal healing of the cornea, the absence of dry eye syndrome, some patients in the postoperative period present asthenopic complaints. Patients may notice a decrease in visual acuity when working near, difficulty in refocusing from far to near distance, fuzzy, blurred images, red eyes, tearing, periodic or permanent diplopia at different distances in the postoperative period. Adaptation to emmetropic refraction in these patients can cause discomfort, headache and visual fatigue even with insignificant visual loads, which leads to the development of asthenopia and worsening of their subjective status. Corneal refractive surgery leads to changes in the anatomical and optic parameters of the eye, which contributes to the formation of new accommodation-convergence interactions. If the accommodative and binocular functions were disrupted preoperatively, there is a risk of decompensation and development of postoperative asthenopic syndrome (AS). Refractive surgery, saving patients from glasses and contact lenses, can not completely eliminate their existing imbalances between accommodation and convergence. This can be explained with the fact that the existence of a formed pathological system does not cease with the elimination of the etiologic factor.
