Purpose |
To evaluate the effect of intraocular lens (IOL) color on frequency doubling technology (FDT).
Design |
Randomized clinical trial.
Methods |
For 26 eyes of 26 patients, FDT perimetry (24−2-threshold test) was measured three months after cataract surgery. An acrylic IOL was randomly selected from clear (VA60BB, HOYA) and yellow-tinted lenses (YA60BB, HOYA), which only differed by color. As a control, a further 14 cataractous eyes with visual acuity ≥20/30 were examined. We analyzed mean deviation (MD) and pattern standard deviation (PSD) among the three groups.
Results |
After cataract surgery, MD significantly improved (Fisher protected least significant difference (PLSD): P < .05), but PSD did not change (analysis of variance (ANOVA): P = .94) compared with control values. There was no significant difference between the two IOLs for either MD (Mann-Whitney test; P = .15) or PSD (Mann-Whitney test; P = .84).
Conclusions |
When interpreting the results of FDT, the effect of cataract should be considered but that of IOL color does not need consideration.
