Frequency Doubling Technology Perimetry After Clear and Yellow Intraocular Len Implantation

Purpoe To evaluate the effect of intraocular len (IOL) color on frequency doubling technology (FDT). Deign Randomized clinical trial. Method For 26 eye of 26 patient, FDT perimetry (24−2-threhold tet) wa meaured three month after cataract urgery. An acrylic IOL wa randomly elected from clear (VA60BB, HOYA) and yellow-tinted lene (YA60BB, HOYA), which only differed by color. A a control, a further 14 cataractou eye with viual acuity ≥20/30 were examined. We analyzed mean deviation (MD) and pattern tandard deviation (PD) among the three group. Reult After cataract urgery, MD ignificantly improved (Fiher protected leat ignificant difference (PLD): P < .05), but PD did not change (analyi of variance (ANOVA): P = .94) compared with control value. There wa no ignificant difference between the two IOL for either MD (Mann-Whitney tet; P = .15) or PD (Mann-Whitney tet; P = .84). Concluion When interpreting the reult of FDT, the effect of cataract hould be conidered but that of IOL color doe not need conideration.
