Process of production of therapeutic contact lens and device for carrying out the therapeutic contact lens

摘要

Therapeutic contact lens, process and device for its production and its uses this invention refers to the therapeutic contact lens of bacterial cellulose, to a process and device for its production, as well as its uses. The therapeutic contact lenses according to this invention are indicated for use in cases of corneal regeneration when it presents the need for healing. The production process for such lenses comprises the basic stages of (i) cutting of the membrane still moist in flat circular form; (i I) the cut membrane layout on a mould part;(iii) membrane compression so positioned on the mould part by means of an appropriate compression part; (iv) membrane heating still under compression in the moulding assembly; (v) mould opening and resin application on the lens moulded membrane; And air temperature and circulation for total drying of the moulded lens; and, if necessary, (vii) application of ultraviolet light on the moulded lens for polymerisation of the resin.
