Next-to-the-eye Calcium Carbonate Ointment for Dry Eye
Background
A preparation of calcium carbonate in petrolatum has been shown to provide effective, convenient, long-lasting relief for dry eye symptoms,
when applied to the lower eyelid skin. This method was invented by Donald L. MacKeen, PhD and dry-eyed man.
By a mechanism first reported by MacKeen, the ointment migrates over the eyelid margin and into the tear film. This provides
time release delivery, for several hours, of lipid and calcium carbonate. MacKeen's method has been found effective in various studies,
including
a recent study published in the British Journal of Ophthalmology by Dr. Kazuo Tsubota, ophthalmologist and dry-eyed man.
Because MacKeen's work has led to a number of patents, we get to read about it
in glorious detail in
patent filings.
