Analysis of contact lens cleaning solution and storage solution preparation

2019-09-20
Eye drops are formulated – from Cleaning Solutions and stock solutions for contact lenses to rinses for eye surgery and eye treatments, to strict regulatory requirements and product specifications.


Analysis of contact lens cleaning solution and storage solution preparation

Most eye drops are water-based and, in addition, may also contain salts (eg, sodium hydride), a protective agent. Vaseline for the production of ointments and gel polymers for use as lubricants. The heat-sensitive eye drops can be sterilized by sterilization filtration, or the heat-sensitive components can be separately sterilized and filtered, and then added to the raw materials that have been sterilized.


Durapore or a charged ChargedDuropore sterilizing filter has very low adsorption of the protective agent and can also have a 100% sterilization efficiency at high flow rates and high throughput conditions. In many cases, the positively charged ChargedDurapore membrane greatly reduces the adsorption of the protective agent because many of the protective agents are tetraamines with a positive charge. The repulsion between the same charge causes the positively charged Durapore membrane to adsorb very low positively charged protecting agents.


Pre-filtration for separation purposes Reduces particle content and bioburden before sterilization filtration.

The sterile filtration sterilizing filter maintains reliable rejection of microorganisms during prolonged production.

The requirements of the application filter must be able to provide a stable high flow rate and must be very robust for high volume production.

Sterilization filters must be able to maintain reliable retention of microorganisms during prolonged production.

The filter should not adsorb the protective agent in the product.

The filter Polysepll pre-filter is rugged, reliable, able to withstand changes in the production process, and offers high flow rates and reliable rejection for high volume production.



Air filtration, the commonly used filter is Aerovent to ensure sterilization and virus removal.
