Abstract
A method of attaching a fixation member to an optic comprising providing the optic with a cavity opening adjacent the peripheral edge of the optic with a shoulder in the cavity, inserting an inner end portion of the fixation member into the cavity, transmitting laser energy through the optic to the inner end portion of the fixation member to cause the inner end portion to become flowable, and allowing the flowable portion of the fixation member to harden and interlock with the shoulder to resist withdrawal of the fixation member from the cavity.
Claims11
A method of attaching a fixation member having an inner end portion to an optic of an intraocular lens wherein the optic has a peripheral edge, said method comprising:
- providing the optic with an outwardly opening cavity and with a shoulder within the cavity;
- inserting an inner end portion of the fixation member into the cavity;
- transmitting laser energy in the near infrared band through the optic to the inner end portion of the fixation member and absorbing the laser energy in said inner end portion sufficiently to heat the inner end portion to cause at least some of the inner end portion of the fixation member to flow behind the shoulder;
- and
- allowing the flowable portion of the fixation member to harden and interlock with the shoulder to resist withdrawal from the cavity.
