Plymouth, MA....Tech-Etch has photo etched (photo chemical milling) precision Haptics for Intraocular Lenses used in cataract surgery and other corrective implants since 1978. Polyimide has material characteristics that make it attractive for this medical procedure, in addition to providing the advantages of a 3-piece IOL. It is optimal for foldable IOL silicone or acrylic lenses. Polyimide offers flexibility comparable to polypropylene and PMMA haptics, with greater tensile strength, and superior shape memory. Since polyimide is safe for implant, additional medical applications can be derived from its shape retention spring properties. Tech-etch also photoetches other specialty materials including Titanium, Tungsten, Elgiloy, and Molybdenum for use in medical applications.
