Accommodation disorders in patients with visually intensive labor before LASIK in myopia (clinical cases)

Abstract

Laser keratomileusis in situ (LASIK) is the most common refractive surgery in young patients, the goal of which is to provide high distance vision without the use of glasses. One of the topical aspects of assessing the clinical effectiveness of LASIK is the dynamics of the accommodative function of the eye, which is a professionally significant function of the visual analyzer in patients with visually stressful work (VSW). Three clinical cases are presented, reflecting various states of accommodation (normal, habitual excessive tension of accommodation, asthenic form of accommodative asthenopia), diagnosed (based on the method of objective accommodation and the "quality of life" questionnaire "Computer visual syndrome — 22" in patients with VSW before LASIK. It was determined that that LASIK for various degrees of myopia in patients with VSW requires a comprehensive consideration from the standpoint of diagnosis and (or) correction of accommodative asthenopia based on a personalized approach that takes into account the main types of asthenopia. Correct diagnostics provides adequate treatment from the standpoint of choosing both the actual method (physical factor) and the required optical, amplitude and time parameters of exposure.
