Allergy to Lens Implant Material

Question: I am wondering what the lens implant (IOL) is made of? I have allergies to many things including possibly to some plastics that are used for IV's.

Answer: Historically Lens Implants for Cataract Surgery have been made of three or four types of materials including polymethylmethacylate, silicone copolymers, collagen-silicone copolymers and foldable flexible acrylic materials. Each of these classes of materials has been found to be highly bio compatible over many years of experience. That said, it would be very important for you to fully review your allergic history with your Cataract Surgeon. It is possible that your Cataract Surgeon might request some additional testing from an allergy specialist in order to make certain that there is no real risk of implanting a particular type of material and lens.
