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).

Procédé servant à fixer une paire d'éléments haptiques colorés (20) à un élément optique (10) d'un cristallin artificiel (1) et consistant à pratiquer une paire de trous (12) sur le bord périphérique (17) de l'élément optique (10), à introduire les extrémités (21) des éléments haptiques (20) dans les trous (12), à pointer un laser émettant un rayonnement dans le spectre visible sur l'extrémité de l'élément haptique dans le trou (12) dans l'élément optique (10) et à déclencher le laser de sorte que le rayonnement passe à travers l'élément optique (10) essentiellement sans être absorbé, et est absorbé par l'élément haptique (20), fusionnant ainsi l'élément haptique (20) avec l'élément optique (10).
