    Purpose. The study of dynamics morphometric parameters of anterior segment of the eye after phacoemulsification (PE) and without it in the eyes with high risk of developing primary angle-closure glaucoma (PACG).

    Material and methods. 70 patients (70 eyes) with high risk of developing acute attack of PACG. The age of the patients are 42–74 years, men - 27, women - 43. In 20 eyes - the lens transparency, 38 eyes - initial cataract, 12 eyes - immature cataract of the 2nd degree of density according to Buratto. Patients are divided into 2 groups: the main group consisted of 45 patients who agreed to perform PE (the mean position of the ciliary body occurred in 13 eyes, the posteriorly position - in 32 eyes); the comparison group consisted of 25 patients who categorically refused PE due to high visual functions (0.7–1.0 with correction) and the absence of complaints of vision (the mean position of the ciliary body was in 12 eyes, the posteriorly position - in 13 eyes).

    Revealed changes in anatomical parameters of the eye in both groups. The observation period was up to 5 years.

    Results. Improvement in anatomical parameters of the eye and visual functions was achieved in the main group; in long-term follow-up periods, the development of glaucoma was minimal. In the comparison group, morphometric parameters significantly decreased, the incidence of acute attack of PACG was 25%.

    Conclusion. Clinical assessment of condition of the eyes with short axial lens in long-term period after PE showed that in all cases the risk of acute attack of PACG was eliminated. It is necessary to actively identify patients with high risk of acute attack of PACG for prophylactically perform PE, even if the lens transparency.
