Once a lens is removed, install the new one promptly to avoid contamination from any dust or debris in the air.

Apply a suction cup to the center of the lens.

Pull up on the suction cup to remove the lens from the frame.

If the lens does not remove easily, apply a heated iOpener for one minute and try again.

The original adhesive can be reused if it was not damaged during disassembly. Place the new lens into the frame and apply a heated iOpener for one minute to bond the new lens to the old adhesive.

If the old adhesive was damaged during disassembly, use a spudger to scrape off any remaining adhesive then apply generic adhesive where the old adhesive used to be before installing the new lens.
