Patent attributes
This invention describes a simple intraocular lens (IOL) design with a removable optic, which can be inserted in and removed from a haptic device. In this haptic the anterior and posterior capsules are sealed in order to have a perfect control over the lens epithelial cell proliferation which is thereby restricted to the peripheral part of the capsular bag. Additionally, a ring caliper is described as new surgical device to allow a precise sizing and centration of the anterior capsulorhexis. The removable optic allows repeatable correction of the eye focusing over time in case the optical parameters of the eye have changed due to a variety of factors. By separating the optic part from the haptic part, the optic part can easily be manufactured in any shape matching the optical errors of the eye, including the ocular aberrations. The optic part can be manufactured out of any biomaterial restoring ocular accommodation. The optic part may include prismatic, astigmatic or magnification correction to improve visual performance. The optic part may consist of or include an electronic device for the purpose of artificial vision.
