To evaluate differences in higher–order aberrations (HOAs) in different wavelengths in normal human eyes.
Four normal phakic eyes (mean age, 38.5 ±13.2 [SD yr], mean refractive error, –2.31±2.0 D in spherical equivalent) were measured under cycloplegia. Ocular aberrations up to the 5th order were measured in 6 wavelengths: 5 in visible light (450, 500, 550, 600, and 650 nm) using remodeled spatially resolved refractometry and 1 in near–infrared wavelength (830 nm) using Shack–Hartmann aberrometry. Zernike polynomial coefficients up to the 5th order were determined from the data in each wavelength. We compared each Zernike coefficient and the root mean square (RMS) of total HOAs (THO) (from 3rd–5th order) between each wavelength.
Zernike coefficients were negatively correlated with wavelengths in most but not all eyes. In eyes in which the Zernike coefficients were not significantly correlated with wavelength, the absolute value of the measurement was sufficiently low (< 0.1 µm) to be affected by the measurement error. The C02 and the RMS of THO were significantly negatively correlated with the wavelength in all cases (R2, 0.93–0.96 for C02, 0.89–0.96 for the RMS of THO), although the inclination varied with individuals (from –0.0033– –0.011 in RMS of THO).
Ocular aberrations in human eyes decrease with wavelength and the rate of the decrease varies among individuals.
