Plastic lenses have been inserted into eyes for over 50 years. Earlier models caused problems due to poor surface finish and movement within the eye. Today’s intraocular lenses are made to exceedingly strict requirements with superb surface finish inciting little or no reaction in the eye. Surgical advances mean that the implant can be placed consistently into the eye in a stable position where there is very little possibility of movement or contact with surrounding structures. The intraocular implant is manufactured from an inert soft acrylic material which will not breakdown in the eye and should be capable of safely lasting a lifetime.
