BACKGROUND

To compare biometric parameters, especially lens parameters, in patients with high myopia and anisometropia.

METHODS

Patients with spherical equivalent greater than -6D and at least one eye with an axial length greater than 26 mm and a difference in binocular axial length greater than 2 mm were included in this study. In each patient, the eye with a relatively shorter axial length was assigned to Group S, and the other eye was assigned to Group L. In patients whose binocular axial length difference was greater than 4 mm, the eye with the shorter axial length was assigned to Group S1 and the other eye was assigned to Group L1. In patients whose shorter eye axial was less than 26 mm, the eye with the shorter axial was assigned to Group S2 and the other eye was assigned to Group L2. Central corneal thickness, corneal curvature radius, axial length, anterior chamber depth, lens thickness, white-to-white corneal diameter and the radius of the anterior and posterior lens capsules were compared between Group S and Group L, Groups S1 and L1, and Groups S2 and L2.

RESULTS

Sixty-four people were enrolled in the study. There were 26 people with an axial length difference more than 4 mm (Group S1 and Group L1) and 34 patients with an axial length less than 26 mm (Group S2 and Group L2). No significant differences were found in any parameters except axial length between Group S and Group L, Groups S1 and L1, or Groups S2 and L2 (p > 0.05).

CONCLUSIONS

The anterior parameters of patients with high myopia did not change with the axial length.
