The Ideal Presbyopia Correcting IOL
09.05.2019 O. Kermani, MD12
° Defocuscurve: The patient's best-corrected distance visual acuity, graphed on the Y-axis at zero, which
represents infinity. Minus lenses are added to the best-corrected distance visual acuity. Plotting the acuity
while viewing through a series of progressively more minus lenses creates the defocus curve for near objects.
