PURPOSE: To investigate changes of spherical aberration in eyes with accommodative spasm.
DESIGN: Case reports.
METHODS: Four eyes of two patients with accommodative spasm were studied. Ocular spherical aberration was measured with a Hartmann-Shack wavefront aberrometer for the central 4-mm zone.
RESULTS: The root mean square values of spherical aberration were negative (-0.086 +/- 0.026 microm root mean square). However, when the spasm of accommodation was cured or treated with a cycloplegic agent, the value shifted toward positivity (0.025 +/- 0.004 microm root mean square).
CONCLUSIONS: Excessive accommodative tone is manifested objectively by negative spherical aberration in eyes with accommodative spasm.
