Purpose: To investigate the effect of cataract on the results of FDT perimetry with the Humphrey® MatrixTM perimeter Methods: Subjects scheduled to undergo cataract surgery were prospectively identified and asked to participate in this study. Subjects underwent FDT perimetry using the Humphrey® MatrixTM perimeter in both eyes using the 24–2 full threshold algorithm. Visual field testing was performed within one month prior to, and within six months after cataract surgery. The eye that did not undergo surgery served as a control Results: Reliable data were obtained on 20 eyes of 20 subjects and were included in the analysis. A mean improvement in mean deviation (MD) of 2.51 dB (P=0.017) was observed in the eyes that underwent cataract surgery. The mean improvement in MD attributable to cataract surgery (corrected for improvement in the control eyes) was 2.46 dB (P=0.002). No statistically significant difference was observed in pattern standard deviation (PSD) in the eyes that underwent cataract surgery. No significant difference was observed in the MD or PSD among the control eyes. Conclusions: Cataract removal results in an improvement in the MD with FDT perimetry with the Humphrey® MatrixTM
