Manufacturing Ophthalmic and Contact Lens Solutions

Updated: Oct 20

Ophthalmic solutions include a range of products with different functions such as cleaning, disinfecting and lubricating the eyes in the form of eye drops, or rinsing and storing of contact lenses.

All ophthalmic products must meet a number of safety requirements, including a certification of sterility. Sterility is the absence of microbial contamination which could cause eye infections, possibly leading to severe consequences.


Filtration is typically conducted in the final stage where the finished product is passed through a membrane filter during bottling. The membrane filter has to meet regulatory requirements for bacterial retention, as well as industry specifications for cleanliness, chemical compatibility, process efficiency and reliability. The ZTEC™ P Series Filter Cartridges (Pleated Polyethersulfone (PES) Membrane for Sterile Filtration) is suited for the filtration of ophthalmic solutions:


  • Validated, sterilizing grade, polyethersulfone membrane filter cartridges.  Absolute retention from 0.1 to 0.65 micron

  • Meets ASTM Standards for Sterility

  • Lab validated bacterial retention performance

  • Repeatably Steamable/Sanitizable

  • Pore size, lot and serial number are stamped on each filter element for identification and traceability

  • Consistent, reliable removal of contaminants and microorganism

  • Meets USP Class VI biological test for plastics

  • 100% manufactured, flushed, and integrity tested in ISO Class 7 cleanroom
