Purpose. To develop an objective morphometric criterion of high risk of phacomorphic glaucoma formation in individuals with moderate and high hyperopia and with thickened lens form.

Material and methods. There was carried out a comparative analysis of morphometric indicators of 49 patients (98 eyes) with a hyperopia and of 41 patients (61 eyes) with phacomorphic glaucoma associated with hyperopic refraction. B-scanning and ultrasonic biomicroscopy were used for them. The anterior-posterior eye segment, lens form, cross-sectional US-area of lens and anterior chamber, ciliary body position were determined.

Results. At middle ciliary body position the critical crosssectional US-area of a lens did not depend on anterior-posterior eye segment and was 30.0mm2 and more. At back ciliary body position a dependence of cross-sectional US-area of a lens from anterior-posterior eye segment was revealed, and its critical values were 35.0mm2 and more. The calculation formula of phacomorphic glaucoma risk in persons with a hyperopia is offered.

Conclusions.
1. The developed mathematical calculation risk factor of phacomorphic glaucoma formation in individuals with a hyperopia allows to prognosticate this threatening condition.
2. According to the developed criterion, the presence of high phacomorphic glaucoma risk is detected in 37.7%, the raised risk — in 47.9 % of investigated eyes with a moderate and high hyperopia.

Key words: hyperopia, phacomorphic glaucoma, the lens form, cross-sectional US-area of a lens, ciliary body position
