Abstract
A method for attaching a pair of colored haptics (20) to an optic (10) of an intraocular lens (1), containing the steps of providing the peripheral edge (17) of the optic (10) with a pair of holes (12), inserting the end portions (21) of the haptics (20) into the holes (12), aiming a laser emitting radiation within the visible spectrum at the end portion (21) of the haptic within the hole (12) in the optic (10) and firing the laser so that the radiation passes through the optic (10) essentially without absorption and is absorbed by the haptic (20), thereby causing the haptic (20) to fuse with the optic (10).
