Each intraocular lens manufacturer faces a series of complex choices in deciding which material(s) to use for the production of intraocular lenses.

The choice of materials includes:

  • PMMA (Polymethyl methacrylate)
  • Silicone (molded, using Optoform 80 or Nanoform 250)
  • Hydrophobic polymers
  • Hydrophillic polymers

Factors in the choice of material include:

  • Biocompatibility of the material with the eye, (including checks for cellular proliferation on the lens surface, opacification of the posterior capsule (PCO), etc.)
  • Foldability of the lens material.
  • Market demand and requirements
  • Regulations of government and industry controlling organizations
  • Costs of the material
  • Costs of suitable production methods (and suitability of the material to design and production method)
  • Ease of working with the material (brittleness or propensity to cracking or tearing)

Sterling Ultra Precision can assist interested manufacturers in setting up suitable production processes.
