Subjects wore habitual correction over their left eye and an infrared filter over the right eye during accommodative measurements. Monocular accommodation was measured continuously for two, 30\u2010second periods using a PowerRef I at a sampling rate of 25 Hz while subjects viewed a high\u2010contrast target at 0.25 m. The high (1.0 to 2.3 Hz) and low\u2010 (0 to 0.6 Hz) frequency components of the power spectrum from a fast Fourier transform of the accommodative response were used in analysis. Resting tension on the crystalline lens was assessed by measuring the amplitude of the oscillations of the crystalline lens after a rightward 20\u00b0 saccadic eye movement. Ciliary body thickness was measured 2 mm posterior to the scleral spur from images obtained with a Zeiss Visante optical coherence tomography (OCT). Cycloplegic spherical equivalent refractive error was obtained with the Grand Seiko autorefractor.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results.<\/jats:title>\n                    <jats:p>The mean \u00b1 SD spherical equivalent refractive error was \u22121.00 D \u00b1 2.25 (range, \u22126.00 D to +3.44 D). Greater power in the log of the high\u2010frequency component of accommodative microfluctuations was associated with thinner ciliary bodies (p = 0.03) and lower ages (p = 0.0004). More hyperopic refractive errors with greater power in the high\u2010frequency component (p = 0.0005) and the low\u2010frequency component (p = 0.02). No statistically significant relationship was found for the low\u2010frequency component or root mean square of accommodative microfluctuations and refractive error.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions.<\/jats:title>\n                    <jats:p>High\u2010frequency microfluctuations of accommodation appear to be suppressed with thicker ciliary bodies.
