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 μm 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 μm root mean square).
Conclusions |
Excessive accommodative tone is manifested objectively by negative spherical aberration in eyes with accommodative spasm.
