Freshkote PF is a single product rather than a broad line, and that focus is rather the point. It is a preservative free lubricant eye drop supplied in a multi dose bottle, which is a less ordinary combination than it sounds. Most preservative free drops arrive in single use vials, and most multi dose bottles contain a preservative.
A multi dose bottle with no preservative in it has to rely on the bottle instead, using a valve and filter design that keeps the contents from being contaminated as the bottle is used. The practical result is a bottle you can carry and reach for repeatedly, without the preservative that some people react to, and without a strip of vials to open and discard.
We carry Freshkote PF as a pack of two bottles. The formula is designed with all three layers of the tear film in mind, and it is described as suitable for use alongside contact lens wear.
Compare it against the two neighboring formats we stock. Preservative free vials suit people who want an unopened dose every time and do not mind the packaging. Preserved bottles are usually the cheapest per milliliter and are fine where drops are occasional. A preservative free bottle sits between them and tends to appeal to people who reach for drops several times a day.
Work out cost per use before you decide, since a two pack changes the arithmetic against a single bottle elsewhere. If you are not sure whether a preservative free product is the right fit for you, ask your eye care professional.
