Abstract
Exemplary arrangements include articles and methods of producing plastic material objects. Such objects may be configured for use as an ocular implant, and intraocular lens, or a contact lens. Exemplary methods include ablating and polishing plastic material in a processing region of a plastic material object through operation of at least one laser such that some material in the region is de-crosslinked. Exemplary methods also include subsequently irradiating the processing region to at least partially re-cross-link the plastic material.

-16. (canceled)
A method comprising:
- a) ablating plastic material in a processing region of a plastic material object through operation of at least one laser, wherein at least some of the plastic material in the processing region is de-crosslinked,
- b) polishing plastic material in the processing region through operation of the at least one laser,
- c) subsequent to (b), irradiating plastic material in the processing region, wherein at least some of the plastic material in the processing region at least partially regains crosslinking.
An article produced by a method comprising:
- a) ablating plastic material in a processing region of a plastic material object through operation of at least one laser, wherein at least some of the plastic material in the processing region is de-crosslinked,
- b) polishing plastic material in the processing region through operation of the at least one laser,
- c) subsequent to (b), irradiating plastic material in the processing region, wherein at least some of the plastic material in the processing region at least partially regains crosslinking.
An article comprising:
- a plastic body configured to be used as one of an ocular implant, an intraocular lens or a contact lens, wherein the plastic body includes
- a laser ablation formed and polished, and subsequently irradiated, processing region,
- wherein the processing region comprises irradiation crosslinked plastic.
