Abstract

Purpose : The purpose of this study is to evaluate the effect of an aspheric monofocal intraocular lens (IOL) in peripheral aberrations along the horizontal visual field.

Methods : Aberrations were measured using a peripheral Hartmann-Shack wavefront sensor from +30 to -30 degrees eccentricity along the horizontal visual field. Zernike polynomials up to 5th order were calculated for each eccentricity and 4mm pupil. Sixteen pseudophakic eyes implanted with an aspheric monofocal IOL were included in this study. Data were collected one month after surgery.

Results : The average of spherical equivalent (M) and cylinder (J0) increased quadratically with horizontal eccentricity (R^2=0.99 in both cases, centered at 3 degrees in the temporal visual field) and the average of J45 increased linearly (R^2=0.90) with the horizontal eccentricity. Whereas the average trend in J45 was well below standard deviation, the myopic shift for M and J0 exceeded the standard deviation with more than a factor of two. The myopic shift at 30 degrees was equal for M and J0 (p>0.05 for the nasal and temporal field of view) and significantly higher in the nasal than in the temporal field of view (1.5D for temporal and 3D for nasal field of view, p<0.05 for M and J0). The rate of change for J45 was 0.004 D/degree. Spherical aberration (C4,0) was independent of the eccentricity (R^2=0.04) and close to zero along the horizontal visual field (average value was 0.01±0.01 microns along the horizontal axis and 0.02±0.05 microns on-axis). Similar trend was found for vertical coma (C3,-1) with average value of 0.04±0.01 microns along the horizontal visual field (R^2=0.4 with a rate of change of 0.0005 microns/degree). Horizontal coma (C3,1) changed linearly (R^2=0.98) with eccentricity and had a rate of change of 0.005 microns/degree.

Conclusions : Sphere and cylinder increased along the horizontal visual field in eyes implanted with an aspheric monofocal IOL, as it has been previously reported in pseudophakic eyes implanted with standard monofocal IOLs (Jaeken et al. IOVS 2013). Spherical aberration and vertical coma provided an average on- and off-axis value close to zero and were independent of the eccentricity. Horizontal coma provided a rate of change along the horizontal visual field similar to that of young phakic eyes and lower than for old phakic eyes (Baskaran at al. Optom Vis Sci 2011).
