Why Polyethylene Glycol

An ideal contact lens material should be highly wettable, biocompatible with ocular tissues, resist dehydration, and promote healthy oxygen flow to the cornea.

The chemical compound Polyethylene Glycol used in our materials nd contact lenses can deliver on all these features. That is why Ocutec Ltd. has made PEG the core of its OcuPEG soft contact lens materials and lenses.

Because PEG molecules possess multiple water binding sites, they demonstrate very strong affinity for water. PEG rapidly hydrates and swells dramatically, up to 1000%. Non-toxic and biologically inert, PEG tightly binds water to polymer chains, making it ideal for many biomedical applications, including opthalmic drugs and wound dressing products. PEG’s intrinsic oxygen permeability makes it ideal for soft contact lenses.
