Abstract
The invention provides a medical device and method to reduce the occurrence of pseudophakic pupillary block following implantation of an intraocular lens. The device includes an intraocular lens configured with channels traversing through the surfaces of the lens optic. The invention includes special edge angulations and locations in the optic zone that eliminate optical distortion from channels. The channels perform as valves configured to allow flow of a patient's aqueous humor from one surface of the lens through to the other surface of the lens, thereby preventing fluid pressure from building up in a patient's eye.
