Abstract
Purpose :
To evaluate the longitudinal chromatic aberration (LCA) using a multiwavelength wavefront sensor in pseudophakic eyes after implantation of various intraocular lenses (IOLs) .
Methods :
Forty-three eyes of 36 pseudophakic patients were examined. Patents’ age ranged from 29 to 86 years (70.8 ± 9.5 years, mean ± SD). IOLs implanted included SN60WF or SN60AT (Alcon) in 11 eyes, NY60 (HOYA) in 5 eyes, XY1 (HOYA) in 11 eyes, and ZCB00V (AMO) in 16 eyes. Wavefront sensing was conducted using a newly developed multiwavelength wavefront sensor with three different light sources (561, 690, 840 nm), and LCA in diopters were calculated between 561 and 840 nm lights. The obtained data were compared among IOLs.
Results :
LCA (840 - 561) was 0.96 ± 0.11 D in eyes with SN60WF and SN60AT, 0.80 ± 0.06 D in eyes with NY60, 1.01 ± 0.09 D in eyes with XY1, and 0.66 ± 0.06 D in eyes with ZCB00V. LCA was similar between SN60WF/SN60AT and XY1. LCA was significantly smaller with NY60 and ZCB00V than with SN60WF/SN60AT and XY1 (P < 0.05, Kruskal - Wallis with Bonferroni test). ZCB00V showed the smallest LCA value among the IOLs (P < 0.05). LCA had positive correlation with IOL power in eyes with SN60WF/SN60AT and XY1, but not in those with NY60 and ZCB00V.
Conclusions :
Using multiwavelength wavefront sensor, LCA could be quantitated in pseudophakic eyes. Our results indicate that LCA varies depending on the IOL material and power, and ZCB00V showed the smallest LCA which did not increase even with higher IOL diopters.
