Wavefront analysis in eyes with accommodative spasm.
OBJECTIVE
To investigate changes of spherical aberration in eyes with accommodative spasm.


METHODS
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.
