Abstract

Purpose: The aim of this study was to assess the axial length/corneal radius of curvature ratio changes after posterior scleral reinforcement (PSR) for pathologic myopia.

Procedures: This study enrolled 32 pathologically myopic eyes treated with PSR and 35 untreated pathologically myopic eyes. Axial length, refractive error, best corrected visual acuity, corneal radius of curvature, and the axial length/corneal radius of curvature ratio were evaluated during the 1-year follow-up.

Results: There were no statistical differences in each parameter between the 2 groups at baseline. Significant differences were found between the 2 groups in both axial elongation and best corrected visual acuity improvement. The average axial length/horizontal corneal radius of curvature ratio significantly decreased in the PSR group.

Conclusion: The PSR surgery can effectively delay the axial elongation in pathological myopia. Axial length/horizontal corneal radius of curvature ratio significantly decreased, which may indicate less myopic progression after surgery.
