The dysphotopia that is connected to the reflection of light from the intraocular lens (IOL) edge is analyzed. A new IOL with 'Sigma' edge is investigated, and other three IOLs are also studied for comparison. The interaction of rays as a function of edge design was evaluated in an experimental model of the pseudophakic eye using the ray-tracing program of ZEMAX software (Focus Software, Inc.). The results show the rays crossing the edges of IOLs form an image with the shape of a partial ring or thin arc in the periphery of the retina, the potential of the 'Sigma' edge to lower dysphotopsia for pseudophakic patients is promising.
