The invention is the method of preparing macromer for use in making ophthalmic lenses comprising combining two or more monomers and using a macromer-forming catalyst, wherein the macromer-forming catalyst comprises triethylamine or bismuth.

Macromer forming catalysts

A soft contact lens containing a silicone-hydrogel made by curing a reaction mixture containing a silicone-containing monomer.

Soft contact lenses

The invention provides a packaging solution for use with hydrophobic contact lenses. The packaging solution of the invention substantially prevents adherence of the lenses to the packages' surfaces, thus preventing deformation or breakage of the lens.

Contact lens packaging solutions

Acylphosphine initiators used in making ophthalmic lenses are stabilized by the addition of an acid to the monomer mix used to make the lenses.

Stable initiator system

A wettable silicone hydrogel made by including a high molecular weight hydrophilic polymer into the silicone hydrogel monomer mix is presented. The hydrophilic polymer is entrapped in the hydrogel with little or no covalent bonding between it and the hydrogel matrix.
