Ophthalmic devices with stabilization features
This invention discloses methods and apparatus for forming Ophthalmic Lenses with Stabilizing Features, and more specifically, Ophthalmic Lenses that include an encapsulated Insert Device.
1. An ophthalmic device with at least one stabilizing feature, the ophthalmic device comprising:
a lens comprising a biocompatible material, wherein the biocompatible material allows for placement of the lens on an eye;
a first rigid insert integral with the lens; and
at least one stabilizing feature comprising a second rigid insert and a third rigid insert, wherein the stabilizing feature orients the lens when the ophthalmic device is placed on the eye.
2. The ophthalmic device of claim 1 , wherein the stabilizing feature alters a front surface topography of the ophthalmic device.
3. The ophthalmic device of claim 1 , wherein the lens forms from polymerizing a reactive monomer mixture into a hydrogel between a front curve mold and a back curve mold.
4. The ophthalmic device of claim 1 , wherein at least one of the second rigid insert and the third rigid insert comprises a coloration or a marking, wherein the coloration or the marking is a visible orientation cue.
5. The ophthalmic device of claim 1 , wherein the biocompatible material comprises a polymerized hydrogel.
6. The ophthalmic device of claim 5 , wherein the polymerized hydrogel comprises a silicone.
7. The ophthalmic device of claim 1 , wherein the first rigid insert comprises a thermoformed three-dimensional shape.
8. The ophthalmic device of claim 1 , wherein the lens encapsulates the first rigid insert.
9. The ophthalmic device of claim 1 , wherein the first rigid insert is in direct contact with the atmosphere and a cornea of an eye on respective anterior and posterior surfaces.
10. The ophthalmic device of claim 1 , wherein the first rigid insert is asymmetrical.
11. The ophthalmic device of claim 1 , wherein the first rigid insert comprises zones having different indices of refraction.
12. The ophthalmic device of claim 11 , wherein the zones are tailored to correct for astigmatic characteristics of the eye.
13. The ophthalmic device of claim 12 , wherein the stabilizing feature properly orients the ophthalmic device on the eye by aligning the zones with their corresponding regions of the eye.
