Abstract

Background. In recent years the refractive therapy with orthokeratology lenses (OKL) has become the most popular among the effective ones. The efficiency of the method is determined by several initial parameters of a patient, including the diameter of the pupil. The purpose was to study the influence of pupil diameter on the eye axial length in patients with myopia who use orthokerato­logy lenses. Materials and methods. The examination involved 120 children divided into 2 groups. The group I used OKL, group II used glasses with total correction. Results. Group I demonstrated a strong correlation between the diameter of the pupil and myopia progression gradient; group II showed no correlation. Conclusions. The most effective method of control for an advanced form of myopia and baseline dimension of the lens less than 4.52 mm is an application of refractive therapy with orthokeratology lenses.
