ABSTRACT:
An artificial intraocular lens intended to be operated into the anterior chamber of the eye. The lens comprises an optical portion, and a haptic portion. A pressure equalizing aperture is provided so closely to the optical center of the optical portion that the pressure equalizing aperture will cause pressure equalization between the anterior chamber and the posterior chamber of the eye without use of iridectomy, thus preventing glaucoma from developing due to the fact that iris lies in contact with the optical portion.
