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.
