Manufacturing Ophthalmic and Contact Lens Solutions
Updated: Oct 20, 2020
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:
