In this presentation, Dr. Samuel Masket explains pseudophakic dysphotopsia and shares 5 pearls for managing the visual phenomena:

• Know the different types of dysphotopsia (diffractive optic, positive, negative).
• Know how to exchange single-piece intraocular lenses (IOLs) and be aware of varying haptic designs.
• Positive dysphotopsia is induced by square-edge IOL design and high index of refraction; it is IOL-design specific.
• Negative dysphotopsia is induced by any IOL type or design; it is related to IOL position in the eye.
• Listen to and work with the dysphotopic patient.
