Abstract
This invention describes the use of polymerizable surfactants as comonomers in forming ophthalmic devices such as contact lenses, intraocular lenses, corneal implants, etc.
Claims30
An ophthalmic device comprising:
- a polymerized comonomer mixture comprising at least one polymerizable surfactant selected from the group consisting of poloxamers having at least one end terminal functionalized, reverse poloxamers having at least one end terminal functionalized, poloxamines having at least one end terminal functionalized, reverse poloxamines having at least one end terminal functionalized and mixtures thereof.
A method of forming an ophthalmic device comprising:
- providing a polymerizable mixture comprising a comonomer mixture comprising at least one polymerizable surfactant selected from the group consisting of poloxamers having at least one end terminal functionalized, reverse poloxamers having at least one end terminal functionalized, poloxamines having at least one end terminal functionalized, reverse poloxamines having at least one end terminal functionalized and mixtures thereof;
- subjecting the polymerizable mixture to polymerizing conditions;
- and,
- shaping the polymerizable mixture into the desired shape of the ophthalmic device.
