Zusammenfassung:	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.
