Abstract

The present disclosure provides coverings such as contact lenses which can be used to provide improved vision in an eye of a subject, such as a human or animal subject. The coverings may comprise a pillar and a plurality of fenestrations. In some cases, an annular region such as a lenticular volume may be formed on the eye of the subject which may provide enhance comfort while the covering is in use. The coverings provided herein may have uses and applications such as masking an astigmatism of an eye, correcting a refractive error of an eye, the treatment of an eye having epithelial defects, aberration correction, multifocal correction, presbyopia correction, and other applications. Some embodiments of the present disclosure comprise extended wear contact lenses.

Claims (24)

1 . An astigmatism-masking contact lens, the contact lens comprising:

an inner portion comprising an anterior surface, wherein the inner portion comprises a pillar and an annular region disposed around the pillar; and

a peripheral portion disposed radially outward from the inner portion and having a posterior surface configured to contact a surface of an eye when disposed thereon;

wherein a portion of a posterior surface of the pillar is configured to contact a cornea of the eye when disposed thereon,

wherein a posterior surface of the annular region has a curvature which diverges from a refractive shape of the cornea such that the posterior surface of the annular region vaults to form a lenticular volume therebetween when disposed thereon.

2 . The contact lens of claim 1 , wherein the pillar is disposed in a central location of the inner portion.

3 . The contact lens of claim 1 , wherein the posterior surface of the pillar has a curvature that is configured to contact a cornea of the eye when disposed thereon.

4 . The contact lens of claim 3 , wherein at least one fenestration of the plurality of fenestrations is disposed outside an optic zone of the inner portion.

5 . The contact lens of claim 1 , further comprising a plurality of fenestrations disposed in the inner portion, the outer portion, or both the inner portion and the outer portion.

6 . The contact lens of claim 5 , wherein the plurality of fenestrations is configured to induce flow of tear fluid into and out of the lenticular volume when the eye blinks.

7 . The contact lens of claim 5 , wherein at least one fenestration of the plurality of fenestrations extends from an anterior surface of the peripheral portion to the posterior surface of the peripheral portion.

8 . The contact lens of claim 7 , wherein the posterior surface of the peripheral portion comprises one or more grooves configured to provide a fluid flow pathway between the at least one fenestration and the lenticular volume.

9 . The contact lens of claim 5 , wherein at least one fenestration of the plurality of fenestrations extends from the anterior surface of the inner portion to the posterior surface of the annular region.

10 . The contact lens of claim 5 , wherein the inner portion further comprises an outer region disposed between the annular region and the peripheral portion and configured to contact the eye when disposed thereon.

11 . The contact lens of claim 10 , wherein at least one fenestration of the plurality of fenestrations extends from the anterior surface of the inner portion to a posterior surface of the outer region.

12 . The contact lens of claim 11 , wherein the posterior surface of the outer region comprises one or more grooves thereon configured to provide a fluid flow pathway between the at least one fenestration and the lenticular volume.

13 . The contact lens of claim 1 , wherein the inner portion is configured to mask astigmatism independent of the orientation of contact lens about a central optical axis of the cornea.

14 . The contact lens of claim 1 , wherein the pillar has a width of no more than about 2 mm.

15 . The contact lens of claim 14 , wherein the pillar has a width of 0.5 mm or less.

16 . The contact lens of claim 1 , wherein the pillar has a thickness within a range of about 5 micrometers to about 30 micrometers.

17 . The contact lens of claim 1 , wherein the pillar has a thickness of 5 micrometers or less.

18 . The contact lens of claim 1 , wherein the annular region has an outer diameter of about 2.5 mm to about 7 mm.

19 . The contact lens of claim 1 , wherein the lenticular volume has a sagittal height of about 3 micrometers to about 9 micrometers.

20 . The contact lens of claim 1 , wherein the annular region is formed by molding or etching.
